Research Seminar – Dr. Hongbo Ma, Environmental and human health implications of antimicrobials in personal care products: from triclosan and triclocarban to their replacement compounds
November 19, 2018 @ 12:30 pm - 1:30 pmFree
Dr. Hongbo Ma, Assistant Professor of Environmental Health Sciences at the UWM Zilber School of Public Health, presents her research on the environmental and human health implications of antimicrobials in personal care products.
Research in Dr. Ma’s environmental toxicology laboratory centers on understanding toxicity effects and human health implications of environmental chemical contaminants using alternative animal models such as the nematode C. elegans and zebrafish. Tools and techniques from environmental chemistry, toxicology, and risk assessment are applied and integrated to tackle a broad range of environmental chemicals of human health concern, from conventional heavy metals to emerging pharmaceuticals and personal care products (PPCPs) and algal toxins. Current ongoing projects focus on the following four areas:
1) Identification and mechanistic understanding of neurodevelopmental toxicity of metals and metal mixtures using transgenic C. elegans and zebrafish;
2) Understanding the toxicological effects and human health implications of TiO2 in food additives using the C. elegans model;
3) Screening and characterization of toxicity effects of alternative antimicrobial agents used in personal care products using a worm and fish based model system;
4) Toxicity and risk characterization of several groups of newly identified cyanopeptides (anabaenopeptins and cyanopeptolins) using C. elegans as a model organism.
Dr. Ma’s teaching interests include environmental health sciences, environmental risk assessment, environmental toxicology, and MPH field practicum and Capstone project related to these areas.
