Blase C. Billack


Dr. Billack completed his B.S. degree in Chemistry at the University of Richmond. Under the mentorship of Professor Jeffrey Laskin, Dr. Billack earned his PhD in Toxicology from the Joint Graduate Program in Toxicology UMDNJ/Rutgers. He then pursued an additional two years of postdoctoral training in the area of molecular oncology at the Strang Cancer Prevention Center, on the campus of the Weill Medical College of Cornell University, under the direction of Dr. Alvaro Monteiro where he worked on BRCA 1 mutations and hereditary breast cancer. Dr. Billack is currently a Professor in the Department of Pharmaceutical Sciences in the College of Pharmacy and Health Sciences at St. John’s University. He has taught at both the NYC campus and Rome campus through the St. John’s University Discover Italy program. Dr. Billack has mentored 11 undergraduate and 16 graduate students. He has over 40 peer-reviewed publications, mostly in the area of in vitro toxicology but recently has expanded the focus of his lab towards rodent models of chemical injury. The primary goal of the ongoing research in his lab is to identify novel and effective countermeasures to chemical threats. He has been a member of the Society of Toxicology since 1999.current as of August 3, 2021.
