Troy Hubbard, Ph.D. is an Intramural Research Training Award (IRTA) Fellow in the Toxicology Branch of the Division of the National Toxicology Program (DNTP) at the National Institute of Environmental Health Sciences. As a study scientist, Hubbard works in cross-functional teams to evaluate the potential toxicity and carcinogenicity of chemical agents nominated to the NTP testing program, such as pharmaceuticals, botanicals, and environmental contaminants. Hubbard is responsible for design and implementation of toxicity studies and communicating study results by preparation of NTP technical reports and writing of manuscripts for publication. His primary research interests include hepatotoxicity, respiratory toxicology, and immunotoxicology.

Hubbard obtained his Bachelor of Arts degree in Biochemistry from Hood College in Frederick, Maryland in 2012, and a Ph.D. in Biochemistry, Microbiology, and Molecular Biology from The Pennsylvania State University under the mentorship of Dr. Gary Perdew in 2017. His dissertation research investigated the physiological and toxicological implications of the aryl hydrocarbon receptor (AHR), with a particular focus upon differential smoke toxicity between humans and Neanderthals as a result of evolutionary divergence of AHR ligand selectivity.
