Professor & Associate Dean, Director - Office For Undergraduate Research (OUR)
Office: LIB 210
Lab: BSF 123, 125
Richard S. Pollenz earned a BS degree in Toxicology from the Philadelphia College of Pharmacy and Science and a PhD in Cellular, Molecular and Structural Biology from Northwestern University. He was a tenured faculty member at the Medical University of South Carolina prior to taking a position within the Biology Department at the University of South Florida in 2000. Dr. Pollenz’s research program has been funded by the National Institute of Environmental Health Sciences (NIEHS) and focused on aspects of molecular toxicology. His research included studies of gene regulation and protein degradation mediated by environmental chemicals such as TCDD. His lab published over 50 peer-reviewed manuscripts in many of the top journals including the Proceedings of the National Academy of Sciences, Molecular Pharmacology, Journal of Biological Chemistry and Toxicological Sciences.
He was named a Fellow to the American Association for the Advancement of Science (AAAS) for his contributions to the field of Molecular Pharmacology in 2013.Dr. Pollenz served USF as the Associate Dean in the USF Graduate School between 2008-2011 where he developed numerous professional development workshops for graduate students and used institutional data analysis to help inform practices and procedures.
He is currently serving USF as an Associate Dean within Undergraduate Studies as the Director of the Office for Undergraduate Research (OUR). In this role, Dr. Pollenz continues to investigate innovations in teaching and learning that engage undergraduates in research to enhance their academic progression and professional development.

STEM Education Research, Environmental Molecular Toxicology, Cell Biology
Since 2012 my research focus is exclusively in the area of Discipline Based Education Research or DBER. Several grants and publications in this area are pending. Specifically, I am engaged in big data analysis of >25,000 student records to determine true persistence rates for STEM and non STEM majors and to identify areas within the curriculum that may be modified to promote greater retention and achieve higher learning gains. I am also very interested in innovative methods to teach the natural sciences (flipped classrooms, inquiry-based, high impact practices, etc.) and to measure learning outcomes such as the use of mobile applications and competency-based assessments. Finally, we endeavor to develop and evaluate innovative methods to increase institutional capacity for undergraduate research. Although CMMB does not currently have a biology education track for the PhD, there are several DBER faculty in the SNSM departments and students interested in these or other STEM education research areas should contact me directly to discuss the possibility for graduate work.
