Jennifer Duringer, PhD—President

Dr. Duringer is a Research Associate at Oregon State University in the Department of Environmental & Molecular Toxicology. Her research examines the biochemical effects, mechanisms of toxicity and ultimate biotransformation of plant and fungal toxicants in humans and animals; and phytoruminal bioremediation of explosives, with the goal of cleaning up contaminated lands so that they no longer pose a public health threat and ultimately return them to agricultural and other productive uses. She received her PhD in Toxicology from Oregon State University in 2003, as well as her BS in Zoology and BA in International Studies in 1998. She has been a member of SOT since graduate school and was part of the founding group that organized the Postdoctoral Assembly, serving as co-chair then chair from 2005–2007.

Dr. Mohanan has co-authored more than 20 peer-reviewed scientific publications and book chapters. Sunish's previous industry experience include Principal Pathologist role in the Preclinical Safety Assessment group at Eli Lilly and Company and in that role he applied his toxicology and pathology expertise toward oncology drug development projects. Presently, as Director of Pathology at GSK Dr. Mohanan focuses on drug safety, clinical biomarkers, novel cancer epigenetics targets and immunopathology. He is also involved in biomarker strategy development, external contract research organization partnerships, and is active in various Society of Toxicologic Pathology committees.

Dr. Robin D. Tucker, DABT, DVM—Secretary/Treasurer

Dr. Robin D. Tucker is the Senior Clinical Veterinarian and Assistant Professor of Pathology at Georgetown University Medical Center, where she has performed medicine and surgery for multiple species, as well as provided expertise in pre-clinical safety and risk assessment (toxicology). She received her doctorate in Veterinary Medicine from the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech in 1998, and is a Diplomate of the American Board of Toxicology (2005). She has also worked in Contract Research Organizations (in toxicology) and is very familiar with GLP requirements. She has been a member of the SOT since 2013.

Jacqueline Kinyamu-Akunda, DVM, PhD—Past President/Councilor

Dr. Kinyamu-Akunda is a Director of Preclinical Safety (PCS) at Novartis Institutes of BioMedical Research (NIBR). In her role as a safety assessment expert, she is responsible for all the nonclinical safety aspects of drug candidates in development including the nonclinical strategy, study designs and interpretation, and nonclinical content of clinical and regulatory submissions. She also ensures resolution of nonclinical issues arising during discovery, clinical development or patient use. Jacqueline is also an adjunct Faculty in the Joint Graduate Program in Toxicology at Rutgers University. Before joining Novartis in 2011, Jacqueline was a Toxicology Project Leader at Eli Lilly and Company.

Marcus S. Delatte, PhD—Councilor

Dr. Delatte became a scientist based on his interests to understand the effects of drugs in organisms and to impact public health. His interests led him to earn a PhD in Pharmacology from the Louisiana State University Health Sciences Center (2004) and to complete a postdoctoral fellowship at the Harvard Medical School/McLean Hospital (2008). As a graduate student, he designed and conducted experiments focused on understanding the effects of drugs on simple and complex behaviors in various animal species. This research resulted in the publication of a variety of peer-reviewed research articles on the neurotoxic effects of MDMA ("ecstasy") in new world monkeys and rats; the disruptive effects of delta9-THC (psychoactive ingredient in marijuana) on learning in acutely and daily treated rats; and the self-administration of cocaine in old world monkeys. Findings from these studies provided him with an in-depth understanding of the effects of different drug classes on behavior studied in various contexts. As a postdoctoral fellow in the Department of Psychiatry at the Harvard Medical School/McLean Hospital, he studied the effects of drugs on behavioral and physiological endpoints measured in monkeys. His research focused on the evaluation of cannabinergic drugs synthesized via a collaborative project with a Chemistry laboratory that developed potential pharmacotherapies for cannabis addiction. This research resulted in the publication of peer-reviewed research articles on the pharmacological profile of novel cannabinergic ligands in monkeys and the formal introduction of Dr. Delatte to the drug discovery process. These experiences increased his drive to help develop treatment approaches for patients with substance-abuse disorders. Following the completion of his fellowship, Dr. Delatte joined the Food and Drug Administration (FDA) as a Pharmacology/Toxicology Reviewer. At the FDA, he currently reviews applications to conduct clinical studies, as well as to acquire marketing approval for pharmaceutical products. These applications typically cover therapeutics developed as antidote, analgesic, anesthetic, or addiction medications. Overall, Dr. Delatte's experience in drug compound research and development is extensive and includes nearly nine years of experience advising companies on regulatory and safety issues related to conducting clinical trials and gaining marketing approval for products. These experiences enabled him to serve as teaching faculty at the LSUHSC (Medical Pharmacology course) and the Foundation for Advanced Education in Sciences Graduate School at the National Institutes of Health (Nonclinical Evaluation of Novel Drugs and Beyond course). Dr. Delatte continues to work hard to expand his impact on public health issues by advising individual scientists and companies on how to develop pharmacotherapies and by mentoring young scientists.
