ANTIDOTE Class of 2021

Advancing New Toxicology Investigators In Drug Abuse and Original Translational Research Efforts (ANTIDOTE) a collaboration between the ToxInnovation Lab (UMASS) and The Chai Lab (Harvard Medical School), and sponsored by ACMT. The ANTIDOTE Institute was initiated in 2021 by Dr. Stephanie Carreiro and Dr. Peter Chai. This program provides an opportunity for fellows and junior faculty to begin to develop their own area of investigation, network with peers and experienced investigators in the field, and gather practical knowledge on topics core to developing a successful research program. Meet the class of 2021!

Aaron S. Frey, DO

University of Virginia Toxicology Fellowship
Charlottesville, VA

ANTIDOTE/Aaron_Frey_Head_Shot_copy.jpg

Dr. Aaron Frey was born and raised in Forest, Virginia. He moved to North Carolina to attend Campbell University for his undergraduate education where he double majored in Spanish and government with a concentration in international studies and minored in history. While in North Carolina, he became a firefighter and emergency medicine technician. His first responder experiences made him want to pursue a career in medicine. He obtained the prerequisite medical school courses from Campbell University and became a student researcher in the cellular biology department. He attended the Via College of Osteopathic Medicine in Blacksburg, Virginia where he continued to work as a student researcher. There, he studied the protective effects of cerium oxide nanoparticles in traumatic brain injury and Parkinson’s Disease. He completed an emergency medicine residency at the Lehigh Valley Health Network in Allentown, Pennsylvania in 2019. He worked in a small, resource-limited hospital in northeast Pennsylvania during the COVID-19 pandemic and treated many critically ill patients. He then decided to pursue additional training in medical toxicology and is currently a medical toxicology fellow at the University of Virginia.
