Interest & Expertise

Dr. Elizabeth Liedhegner is a Team Scientist in the department of Biomedical Sciences at the University of Wisconsin Milwaukee, engaged in understanding cellular signaling pathways in disease processes. She obtained her PhD in 2011 from Case Western Reserve University focusing the utilization of a neuronal cell model to study the oxidative stress and cell signaling pathways induced by the utilization of Levodopa therapy to treat Parkinson's Disease. Dr. Liedhegner conducted her postdoctoral studies at the Medical College of Wisconsin where she utilized mammalian models to study endocannabinoid trafficking mechanism alterations related to post-traumatic stress disorder.

Dr. Liedhegner's current research programs are focused on exploring cellular signaling mechanisms, including oxidative changes, that impact protein function and cellular health in various altered states, such as disease and trauma.   The overall goal of this research is to define cellular mechanisms in culture systems and animal models that are important to disease and disorder development and progression.    For this research, she employs a variety of techniques to assay whole cells including live cell imaging and immunofluorescent staining techniques, examination of signaling changes through reporter assays, and protein modifications that result in altered cellular signaling
