Dr. Meredith Bohannon is currently a postdoctoral associate in the Environmental Sciences and Technology department (ENST) at the University of Maryland (UMD) under the direction of Dr. William Bowerman, Professor and Chair, ENST after completing her PhD in UMD’s Marine-Estuarine-Environmental-Sciences graduate program (MEES). Growing up with biostatistician parents and living near the Chesapeake Bay, Meredith has cultivated a lifelong interest in biology in general and environmental stewardship in particular. Her research focus in graduate school was on the physiological ramifications of toxic environmental contaminants, specifically PCBs, in wild birds at a Superfund site. Her work in graduate school gave her a solid foundation in biomarkers of toxicological interest, physiology from the molecular through the systemic levels, extrapolation of environmental problems to a laboratory setting, and the regulatory process of environmental contaminants. Additionally, Meredith developed a keen interest in teaching and mentoring, which she was able to apply as a TA in graduate school, a supervisor in both graduate school and her postdoctoral position, and additionally as an adjunct lecturer in both the ENST and Biology departments at UMD.
In her current work as a postdoctoral fellow, Meredith is a member of the Joint Analytical Services Lab overseen by Dr. Bowerman, in which she investigates blood levels of organochlorine pesticides and PCBs in bald eagle (Haliaeetus leucocephalus) as part of the ongoing Michigan Bald Eagle Biomonitoring Project. Future work will assess mercury levels in bald eagle feathers. This work improves the understanding of population dynamics in relation to contaminant concentrations.
Advisor: Mary Ann Ottinger; Dissertation: Effects of PCB exposure on hepatic gene expression and enzyme activity in Japanese quail (Coturnix japonica) hatchlings.
Meredith has taught and helped to develop five classes as a lecturer at UMD. She has coordinated a 400-level human physiology lab and a 400-level neurophysiology lab, lectured and lab-coordinated a 200-level anatomy and physiology class, taught a 400-level endocrinology course, and a 400-level environmental toxicology course. These courses utilize lab exercises; data analysis, interpretation, and presentation; and research papers. Meredith is interested in teaching-as-research projects that assess the best teaching strategies for maximizing student learning outcomes, which she is pursuing as a Scholar-level member of the University Teaching and Learning Program offered by the Transformation Teaching and Learning Center at UMD.
