SUMMARY:Freshwater Colloquium – Sources\, Fate\, and Effects of PFAS Mixtures in Great Lakes Ecosystems and Native Fishes
DESCRIPTION:Environmental contamination of PFAS is one of the greatest challenges facing freshwater ecosystems today due to widespread accumulation and a high degree of uncertainty regarding ecological risk and health hazards. PFAS are a large class of man-made chemicals used in a wide range of applications such as metal plating\, food packaging\, non-stick coating\, waterproof and stain-resistant fabrics\, and firefighting foams. Because of their numerous sources and applications\, these chemicals are present in the environment as complex mixtures of many different types of PFAS compounds. Once in the environment\, PFAS do not break down completely due to their highly stable fluorinated carbon bonds\, allowing them to persist and accumulate in water supplies\, biota\, and humans. Our laboratory in the Center for PFAS Research and the Department of Fisheries and Wildlife at Michigan State University investigates the accumulation of PFAS mixtures in the Great Lakes region and the impacts of PFAS exposure on native freshwater fishes. This presentation will discuss our field and laboratory research characterizing the distribution of PFAS in environmental matrices\, the bioaccumulation of PFAS in biota\, and the effects of PFAS on the growth\, reproduction\, and physiological condition of native fishes. Together\, this research can inform evidence-based decision-making surrounding ecosystem health\, remediation\, fish consumption advisories\, and water quality standards in the Great Lakes region.  \nDr. Rachel Leads is an Aquatic Ecotoxicologist and Postdoctoral Research Associate in the Department of Fisheries and Wildlife and Center for PFAS Research at Michigan State University. She received her M.S. in Marine Biology from the College of Charleston and her Ph.D. in Biology from the University of North Texas. Her research characterizes the physiological mechanisms and ecological effects of contaminants and environmental stressors in marine and freshwater organisms. Currently\, Dr. Leads studies the impacts of per- and polyfluoroalkyl substances (PFAS) on native fish in the Great Lakes region. Overall\, her work uses both field and laboratory assessments to understand the mechanisms and impacts of contaminant exposure on aquatic organisms across multiple levels of biological organization\, from molecular to whole-organism responses.  \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

SUMMARY:Freshwater Colloquium – Changing Global Water Tables Over The Past 21\,000 Years
DESCRIPTION:Although groundwater and lakes are vital freshwater reservoirs\, little is known about how their storage volumes or regional distributions change in the long term. In this talk\, I will share results from a global-scale transient simulation of the global water table over the past 21\,000 years\, including both groundwater and lake surfaces. The simulation is obtained using the Water Table Model (WTM)\, forced by climate simulation data and topography that changes through time as a result of glacial isostatic adjustment (GIA). Our results highlight the strong correlation between precipitation and water table depth\, and the impact of melting ice sheets on lake storage. We will discuss the impacts of changing groundwater storage on global sea level\, and will also examine the impacts of lakes and groundwater on GIA.  \nKerry Callaghan is an Assistant Professor at the University of Illinois Chicago. She obtained her PhD from the University of Minnesota\, where she developed the Water Table Model (WTM)\, and then completed a postdoc at the Lamont-Doherty Earth Observatory\, Columbia University\, before starting her current position. Prof. Callaghan’s research focuses on the interactions between water and our changing landscape and Earth system.  \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

SUMMARY:Freshwater Colloquium – Troubled Waters: Impacts of Emerging Contaminants on Early Life Stages of Fish
DESCRIPTION:Historically\, ecotoxicological toxicity studies were conducted with limited connections to human health. The field of environmental toxicology has recently embraced a “one health” approach\, with increased focus on understanding the underlying mechanistic effects to improve species extrapolation. While many are shifting towards in silico and Adverse Outcome Pathway approaches\, in vivo toxicity testing using zebrafish and fathead minnow larvae allows for integrated systematic toxicity screening using physiologically complex endpoints and incorporation of latent and transgenerational effects following early exposure to environmental contaminants. Dr. King-Heiden will share the approach she has used to integrate experimental endpoints useful for predicting latent and long-term risks for adverse health effects in both wildlife and humans\, focusing on her most recent studies using neonicotinoid pesticides and PFAS.  \nDr. King-Heiden is a Professor of Biology and River Studies Center at UW-La Crosse\, who specializes in the field of aquatic toxicology\, developmental biology\, and reproductive physiology. She earned her PhD from UW-Milwaukee Department of Biology\, working with Dr. Carvan at the now School of Freshwater Sciences\, studying the reproductive toxicity of Dioxin. She continued this work as a postdoc at the Molecular and Environmental Toxicity Center at UW Madison\, exploring the latent and transgenerational reproductive toxicity of dioxin\, and developmental toxicity of nanomaterials. She has been in the Biology department at UW-La Crosse since 2008. At this comprehensive university\, she is focused on teaching. Her research revolves around undergraduate and MS students\, with a continued focus discerning the impacts of embryonic exposure to emerging contaminants of concern\, using primarily zebrafish and fathead minnows as a model. Her work reveals how exposure to these contaminants influence physiological and behavioral endpoints of ecological importance\, with implications for ecological resilience as well as human health. This presentation is open to students\, faculty\, staff\, alumni and the public.

SUMMARY:Freshwater Colloquium – Pollution History of Black Carbon (Soot)\, Toxic Metals and PFAS in Green Bay Over the Past Century
DESCRIPTION:Green Bay\, the world’s largest freshwater estuary\, and Milwaukee Harbor have experienced significant ecological and environmental changes\, driven by increased anthropogenic activities and the introduction of invasive species. Designated by EPA as Areas of Concern (AOCs) in the 1980s\, both systems provide natural laboratories for assessing long-term pollution trends. This presentation will explore case studies on the depositional history of black carbon (soot)\, toxic metals (Cu\, Pb\, Zn\, Cd\, Hg\, Co\, Ni\, Cr\, and As)\, and polyfluoroalkyl substances (PFAS) in Green Bay sediments over the past 50-100 years\, with comparative insights from Milwaukee Harbor. \nDr. Guo’s major research focus is on aquatic biogeochemistry\, with an emphasis on the role of natural organic matter in governing the reactivity\, fate and transport of chemical species\, including trace metals\, radionuclides\, nanoparticles\, microplastics\, PFAS\, and other contaminants. He received his Ph.D. degree in Chemical Oceanography from Texas A&M University\, College Station. After working as a postdoc and assistant research scientist at Texas A&M-Galveston\, Dr. Guo joined University of Alaska Fairbanks in 2000 as a research professor in the International Arctic Research Center and then University of Southern Mississippi in 2005 as a faculty member in the Department of Marine Science. Dr. Guo has been a professor in the School of Freshwater Sciences at the University of Wisconsin-Milwaukee since 2012. Dr. Guo has authored/coauthored over 240 peer-reviewed publications\, with an H-index of 70 and over 17\,000 citations based on Google Scholar. His research influence is specifically recognized by ScholarGPS®\, which ranked him #4 globally in Dissolved Organic Carbon and #5 in Organic Matter based on publications from the prior five years (2022). He received the 2023 UWM Senior Faculty Research Award. \nSam earned her B.S. in Geography with a minor in Chemistry from UW-Whitewater in 2024. She just started the second year of her master’s here at SFS working in Dr. Guo’s lab. Her research consists of studying the historical distribution of heavy metals in Milwaukee Harbor and Green Bay sediments\, analyzing the degradation of microplastics and microplastic-derived DOM\, as well as examining PFAS molecular weight distribution via ultrafiltration. This year\, she has had the opportunity to present her research at numerous conferences\, including the Society for Freshwater Sciences annual meeting in San Juan\, PR\, the ACS Great Lakes regional meeting in Appleton\, WI\, and at the International Association for Great Lakes Research in Milwaukee\, WI. \n

SUMMARY:Freshwater Colloquium – First Flush: Rapid Interdisciplinary Response to a 5 Billion Gallon Combined Sewer Overflow
DESCRIPTION:Devastating rain washed chemicals\, biomass\, and combined sewerage into the Milwaukee Harbor from SE Wisconsin. Twice as strong as a 2008 event\, it briefly changed the aquascape of Milwaukee. Our lab time series put the first month of impact into focus using 5 survey cruises including teams from  student classes. Cycles of layering – mixing and wind patterns showed vigorous plankton growth and its chemical draw-down responding on 2-3-day scales to weather patterns. Nutrient evasion into nearshore waters did not persist\, but phytoplankton communities were diversified compared to earlier in the year. Fine coincidence with salmon and perch fishing action. \nOur very own Senior Scientist\, Dr. Russell Cuhel\, will present his talk “First Flush: Rapid Interdisciplinary Response to a 5 Billion Gallon Combined Sewer Overflow”. Sure to be a fascinating discussion on very current topic for all of us. Please join us Monday September 29th @ 3PM in the Ballroom. Arrive before 3PM to enjoy some light refreshments. \n

SUMMARY:Freshwater Colloquium: Occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in Surface Waters of the Chicago Area Waterway System
DESCRIPTION:Gordon Getzinger will present “Occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in Surface Waters of the Chicago Area Waterway System” as part of the School of Freshwater Sciences Spring Colloquium\nDr. Getzinger is an Assistant Professor at Loyola University Chicago in the School of Environmental Sustainability (SES). As an environmental chemist he studies the occurrence and fate of anthropogenic chemicals in natural and engineered systems. Before joining the SES faculty in 2023\, he was a research scientist at Biobot Analytics\, a consultant at Exponent\, and a research scientist with the North Carolina PFAS Testing Network. Additionally\, he has held adjunct/lecturer appointments in the Chemistry Department at Tufts University and the Department of Civil and Environmental Engineering at MIT. He completed his post-doctoral training with the Environmental Chemistry Group at ETH Zurich and his PhD with Professor Lee Ferguson at the Nicholas School of the Environment at Duke University. \nPer- and polyfluoroalkyl substances (PFAS) are a class of organic contaminants occurring ubiquitously in aquatic environments owing to their wide-spread consumer and industrial use and the recalcitrance of carbon-fluorine bonds toward environmental transformations. PFAS accumulate in sediments and biota and are known to cause ecological and human health effects. PFAS use in industry and consumer goods leads to their occurrence in treated wastewater and residual biosolids. Furthermore\, recent research indicates that stormwater may transport PFAS from urban landscapes into aquatic ecosystems. Considering potential future regulations on levels of PFAS in wastewater discharges\, knowledge of PFAS sources in urban aquatic environments is essential for determining efficacy of any proposed discharge limits or ambient water quality standards. The Chicago Area Waterway System (CAWS) presents a unique opportunity for studying the sources and fate of PFAS in urban aquatic systems because the CAWS surface waters are highly impacted by treated wastewater effluent\, combined sewer overflows\, and stormwater runoff. However\, there are currently few data available on levels of PFAS in CAWS surface waters. To better understand current levels of PFAS in the CAWS\, we conducted a monitoring campaign in major CAWS waterways with varying degrees of stormwater runoff and wastewater influence. Samples were analyzed using solid phase extraction and high-performance liquid chromatography tandem mass spectrometry for >30 PFAS of regulatory concern.

SUMMARY:Freshwater Colloquium: Groundwater management in Northeast Wisconsin: Potential for geogenic metals mobilization
DESCRIPTION:Erin Berns-Herrboldt will present “Groundwater management in Northeast Wisconsin: Potential for geogenic metals mobilization” as part of the School of Freshwater Sciences Spring colloquium.\nDr. Erin Berns-Herrboldt is an Assistant Professor of Water Science at the University of Wisconsin – Green Bay. She completed her PhD in Civil Engineering in the Environmental and Water Resources Engineering Program at the University of Texas at Austin and conducted postdoctoral research at Oak Ridge National Laboratory. Her research experience includes studying the fate of organic groundwater contaminants\, biogeochemical controls on carbon release from Arctic permafrost soils\, metals release from aquifer sediments\, and nutrient cycling in stream hyporheic zones. \n\nGroundwater quality can be impacted by metals released from aquifer minerals\, potentially causing human health concerns. When aquifer sediments are relatively undisturbed\, metals bound to minerals remain stable\, but during transitions in water level – due to variations in groundwater recharge or over-pumping – metals can be released to groundwater. This project evaluates the history of groundwater use in the Northeast Wisconsin Groundwater Management Area (GMA) for the confined Cambrian-Ordovician aquifer\, and explores the potential for metals release due to oxidation during aquifer drawdown. \n \nTo evaluate these changes\, (1) groundwater was sampled across the GMA for evaluation of water chemistry\, (2) a monitoring well was installed to improve groundwater level monitoring in the southern portion of the GMA\, and (3) batch leaching experiments were conducted under oxic and anoxic conditions with rock cuttings from the newly installed monitoring well to evaluate potential for metals release. Initial leaching experiment results show that nickel and cobalt increased over time in oxic experiments\, but not in anoxic experiments\, and negligible arsenic was observed over the experimental timeframe. This study provides initial results that support improved understanding of metals release from oxidized GMA aquifer sediments. Findings from this study will inform the development of effective groundwater management strategies\, ensuring the sustainability and safety of water resources in the Northeast Wisconsin GMA. \n\nThe Spring 2025 Freshwater Colloquium series takes place in the GLRF Ballroom. Most talks this semester will involve the theme of Emerging Contaminants in Aquatic Environments. Please join us! \n\n\nThis presentation is open to students\, faculty\, staff\, alumni and the public. \n\n\n\n\n\n\n\n\n \n\nSpring 2025 Colloquium Series schedule.

SUMMARY:Freshwater Colloquium: Novel mechanistic insights into nanoplastics release in natural environment
DESCRIPTION:Boya Xiong will present “Novel mechanistic insights into nanoplastics release in natural environment” as part of the School of Freshwater Sciences spring colloquium.\nDr. Boya Xiong is an assistant professor in the Department of Civil\, Environmental\, and Geo-Engineering at the University of Minnesota\, Twin Cities. Dr. Xiong’s research focuses on the interface of polymer science and environmental engineering\, to i) elucidate the fundamental mechanisms of polymer degradation (e.g.\, micro/nanoplastic generation) that dictate the environmental fate and shape sustainable design and management of future polymer chemicals and materials; ii) develop novel nature-inspired membrane material architecture to enable efficient separation and mitigate pathogenic contamination and fouling in engineered systems. Xiong earned a Ph.D. in Environmental engineering at Pennsylvania State University where she also obtained her M.S. in Agricultural and Biological Engineering. Xiong earned a B.S. in Biotechnology from East China University of Science and Technology. Prior to her appointment\, Xiong was working as a postdoctoral associate at MIT. She was selected as ASCE MN chapter Young Engineer of the Year in 2023 and an American Academy of Environmental Engineers and Scientists 40 Under 40 awardee in 2024. \n  \n\nThe majority of prevalent micro- / nanoplastic (MP/NPs) pollutants are derived from the degradation of bulk plastics in the natural environment. Mechanical degradation (i.e.\, abrasion and fragmentation) is a primary mechanism of MP/NP release; however\, its fundamental understanding remains elusive. Furthermore\, data generated from disparate and qualitative mechanical degradation methods are hard to unify for estimating degradation in a diverse range of environmental conditions. In this talk\, I will highlight how fragmentation and surface abrasive wear play a different role in releasing MP/NPs during the lifetime of plastics. Focusing on abrasive wear\, I will introduce our novel and quantitative methods\, particularly our lateral force microscopy-based nanoscratch method\, to mechanistically probe MP/NP release at a single surface roughness protrusion (asperity) level. Next\, I will highlight the combined effects of photo-oxidization and nanoscale abrasive wear on releasing nanoplastic release. In particular\, I will elucidate the evolution of the wear mechanism and rates of semi-crystalline polyethylene during photooxidation. These results provide an underlying mechanism and key polymer properties responsible for why photooxidation leads to more nanoplastic release via abrasive wear. Our quantitative approach will significantly advance our understanding of MP/NP release in the natural environment. The data will contribute to future predictive modeling of nanoplastic release rate as a function of polymer properties and environmental conditions. Incorporating such models into an environmental risk assessment framework will guide the early-stage design\, selection\, and management of polymer materials for responsible environmental outcomes. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom. Most talks will involve the theme of Emerging Contaminants in Aquatic Environments. Snacks will be available prior to the talk.

SUMMARY:Freshwater Colloquium: Ecogenomics of freshwater lake bacteria
DESCRIPTION:Katherine (Trina) McMahon will present “Ecogenomics of freshwater lake bacteria” as part of the School of Freshwater Sciences Fall colloquium.\n \nProfessor Katherine McMahon received her BS in Civil Engineering and MS in Environmental Engineering from the University of Illinois at Urbana Champaign in 1995 and 1997 respectively. She earned her PhD in Environmental Engineering at the University of California at Berkeley in 2002. She joined the faculty in the Civil and Environmental Engineering Department at the University of Wisconsin Madison in 2003 and became cross-appointed with the Bacteriology Department in 2008. She was promoted to Associate Professor with tenure in 2008 and professor in 2013. Her research interests span multiple dimensions of the “water microbiome” including wastewater treatment and freshwater quality. She has a special interest in wastewater treatment bacteria that sequester phosphorus using an enigmatic physiology. She is heavily invested in the North Temperate Lakes Long Term Ecological Research site and directs the NTL Microbial Observatory. Finally\, she is passionate about future faculty professional development and has served as Co-Faculty Director of the Delta Program in Research\, Teaching\, and Learning at UW-Madison since 2011. She was elected as a fellow in the American Academy of Microbiology in 2018. \n\n \nFreshwater lake bacterial populations are dynamic. Ecological forces alter their community composition and evolutionary processes shape their genomes. In this presentation\, recent findings made possible through a 20-year time series of metagenomic data generated from Lake Mendota\, Madison\, WI will be shared. This study used genome-resolved approaches to examine how population-level diversity changes over time scales from weeks to decades. Results show that aquatic invasive species are restructuring the lake foodweb\, with cascading effects on lake bacteria. Climate change is impacting the populations\, through variation in precipitation patterns and intensity. This unprecedented dataset allows us to view lake bacteria through a genomics lens\, revealing the interacting forces of evolution and ecological drivers. \n\n  \n  \nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.

SUMMARY:Freshwater Colloquium: Microscopy helps reveal how nanoparticulate iron from deep sea hydrothermal vents disperses into open ocean waters
DESCRIPTION:Sarick Matzen will present “Microscopy helps reveal how nanoparticulate iron from deep sea hydrothermal vents disperses into open ocean waters” as part of the School of Freshwater Sciences Spring Colloquium.\n \n\nDr. Sarick Matzen is a soil and environmental geochemist specializing in better understanding trace metal cycling in environmental systems. He is an assistant professor in the Department of Earth and Environmental Sciences at the University of Illinois – Chicago. He received a BA in Environmental Science from Hampshire College (Amherst\, MA)\, a Ph.D. in Environmental Science\, Policy\, and Management at the University of California\, Berkeley\, and conducted NASA and NSF-funded postdoctoral work at the University of Minnesota. He draws on diverse research experiences\, including investigating nuclear waste disposal at Lawrence Livermore National Lab\, community-based soil remediation on urban farms in California\, cycling of limiting nutrients in Earth’s oceans\, and habitability of extraterrestrial ocean worlds\, to determine how the chemical form of contaminants and nutrients explains their landscape-scale transport. \nIron (Fe) is a necessary but often limiting nutrient for life on Earth. Supply by sediments and dust deposition are typically considered the main sources of iron to Earth’s oceans\, but recent advances suggest hydrothermal vents might also be an important source of bio-essential iron over the length scales of ocean basins. Dissolved iron concentrations in hydrothermal fluids are a million times those of surrounding ocean water. Most iron (>90%) precipitates close to vent sources\, but the international GEOTRACES program revealed signatures of hydrothermally-derived iron transported across deep ocean basins worldwide. However\, it remains unclear how this iron persists in the water column rather than being sequestered into sinking particles. Critical processes constraining the export of hydrothermal iron to open ocean waters occur within the first ~100 km of plume evolution. \nTo this end\, we compare hydrothermal plume particulate matter collected from the first 100 km of plumes in the low-sulfur\, high-oxygen Rainbow vent system (Mid Atlantic Ridge) and high-sulfur\, low-oxygen Endeavour vent field (Juan de Fuca Ridge\, North Pacific). We use a novel multimodal approach combining bulk to nano-scale synchrotron-based methods and electron microscopy. We show that plume chemistry affects the mineral phase of iron\, with iron(II) phases persisting longer in the high-sulfur\, low-oxygen Endeavour plume. Yet suspended particle morphology–nanoparticulate iron embedded in carbon matrices–is similar in both plumes. We explore carbon matrix chemistry and potential links to vent microbial communities. Co-located iron and carbon within marine particles drives export of iron from hydrothermal vents to open ocean waters and is a signature of nutrient-rich oceanic hydrothermal activity globally. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.

SUMMARY:Freshwater Colloquium: Data-Efficient Stream Nutrient Modeling: An Application of Data-driven Sparse Sensing
DESCRIPTION:Wasif Bin Mamoon will present “Data-Efficient Stream Nutrient Modeling: An Application of Data-driven Sparse Sensing” as part of the School of Freshwater Sciences Spring Colloquium.\nWasif Bin Mamoon is a PhD candidate in Environmental and Water Resources specialization at Marquette University in Milwaukee\, WI. His research focuses on analyzing stream nutrient (Nitrogen and Phosphorus) dynamics and modeling stream nutrients. He received his BSc and MSc in Water Resources Engineering from Bangladesh University of Engineering and Technology (BUET)\, in 2019 and 2022\, respectively. Previously\, he was a research assistant at the Institute of Water and Flood Management in Bangladesh\, responsible for assessing the impacts of climate change and applying hydrologic and hydraulic models at the watershed scale. \n\nRegular estimation or monitoring of nutrient (i.e.\, nitrogen or phosphorus) concentrations and loads is necessary for assessing stream health and evaluating nutrient pollution mitigation programs. The state of science concludes that at least daily monitoring is necessary. However\, current nutrient monitoring programs involve either infrequent grab samples or costly\, maintenance-intensive in-situ sensors\, resulting in low sampling frequencies and high uncertainties. To address this\, improved stream nutrient monitoring and modeling methods are needed. Data-driven Sparse Sensing (DSS) offers an efficient solution by reliably estimating high-frequency time series from fewer samples\, leading to more efficient sampling designs. This study applies the DSS technique to estimate stream nutrient concentrations and loads (nitrate-nitrite as NOx and phosphorous as P) using sparse measurements of nutrient concentrations and flows. The overall aim is to evaluate how DSS can identify the informative sampling times and locations and reconstruct concentration (NOx and TP) time series with minimal measurements. Furthermore\, this study examines the model’s sensitivity to the size of training data\, time span of monitored data\, and hydrologic regions. This method has a high potential to reduce the cost and effort of nutrient monitoring programs and assessments of catchment material balances. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.

DESCRIPTION:Patrick Gorski will present “PFAS in Wisconsin Surface Water” as part of the School of Freshwater Sciences Spring colloquium.\nDr. Gorski is an Emerging Contaminants Research Scientist at the WDNR in the Bureau of Water Quality. He coordinates statewide surface water monitoring of PFAS in the state and his research focus is PFAS in surface water\, fish tissue and fate and transport issues. He received his PhD from UW-Madison studying mercury bioavailability and bioaccumulation in freshwater systems. Previously\, for 13 years he was an Assistant Scientist and Supervisor at the WI State Laboratory of Hygiene. \n\nIn this talk\, Dr. Gorski will discuss the breadth of PFAS concentrations found throughout the state and give a relative sense of what high and low PFAS concentrations are. He will also highlight specific sites where the DNR has done further study. For the second part\, he will discuss research topics that are being looked into\, such as the vertical distribution of PFAS in the vertical water column of a lake\, development of a PFAS filtration method\, PFAS bioaccumulation in the Madison Lakes\, and what we know about PFAS in sediments and sediment porewater. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom. Most talks will involve the theme of Emerging Contaminants in Aquatic Environments. Snacks will be available prior to the talk. Please join us! \n\n\nThis presentation is open to students\, faculty\, staff\, alumni and the public. \n\n\n\n\n \n\nSpring 2025 Colloquium Series schedule. The Colloquium series creates a platform where students\, faculty\, and scientists discuss emergent issues related to freshwater science research. Invited speakers present specific topics of their research\, as well as policy\, commercial\, and industrial experiences. Everyone is welcome.
