Lei Wang, PhD    Secretary

Lei Wang earned her MS and PhD degrees in Reproductive Physiology from West Virginia University Morgantown, West Virginia in 2009 and 2014, respectively. Subsequently in 2015, Dr. Wang joined the Pathology department at University of Kansas Medical Center (KUMC), Kansas City, Kansas as a postdoctoral fellow, where she worked on epigenetic regulation of trophoblast stem cell differentiation in human placenta and testicular tumor tissues. Dr. Wang’s early career and interest in animal sciences and reproductive physiology started in China where she obtained her BS in Animal Sciences at China Agricultural University, Beijing. Dr. Wang has authored over 20 of scientific papers published in national and international peer-reviewed journals and/or conference abstracts.

In 2016, Dr. Wang joined Charles River Laboratories, Ashland Ohio, where she has been engaged fulltime as a toxicologist and serves as the single point of control (Study Director) for developmental, reproductive, and juvenile toxicity studies for a variety of clients in the pharmaceutical, biotechnology, and chemical industries. She is responsible for the study design, planning, conduct, toxicity date interpretation and reporting of each study, according to FDA, ICH, OECD, and EPA OPPTS guidelines.  Dr. Wang is an active member of Teratology Society and Society for the Study of Reproduction.  Some of her work will be presented in the form of posters and abstracts in the 2019 Annual Meeting of the Teratology Society.

Angela R. Stermer, PhD    Councilor

Angela Stermer, PhD is currently an Associate Principal Scientist in Developmental and Reproductive Toxicology (DART) at Merck & Co in West Point, PA. Prior to her work at Merck she received her PhD form the Univeristy of Texas at Austin (2016), and was a post-doctoral researcher at Brown University (2016-2019). Both of these academic pursuits focused on male reproductive toxicity; determining immune cell responses to toxicity within the testis, and evaluating changes in sperm RNAs as novel biomarkers of testicular toxicity. As a scientist at Merck she primarily acts as a study director on DART toxicology studies, but also as a subject matter expert on reproductive findings across drug candidate programs, and is working towards historical data integration and mining for in vitro DART test systems. She is currently a member of a testicular toxicity specialty group within the IQ consortium’s DruSafe community, and a working group for alternatives to non-human primate DART studies the HESI DART community.
