Background

Dr. Vijay received his initial training in Veterinary Medicine. He earned a bachelor’s degree in veterinary science and animal husbandry with distinction from A.N.G.R. Agricultural University in India. He earned a master’s degree in veterinary science (Major: veterinary pharmacology and Minor: molecular biology and biotechnology) with distinction from G.B. Pant University of Agriculture & Technology in India. Dr. Vijay came to the United States to pursue his doctorate and earned his Ph.D. in comparative biomedical science — pharmacology/toxicology from North Carolina State University in Raleigh, NC. After a brief employment at the NIEHS/National Toxicology Program following his doctorate, Dr. Vijay accepted a postdoctoral researcher (ORISE fellow) position at NCTR in November 2009.

Since November 2012, Dr. Vijay has worked in the capacity of staff fellow in the Personalized Medicine Branch of NCTR’s Division of Systems Biology. The main focus of his research is to identify novel biomarkers of toxicity and diseases. Dr. Vijay has received numerous awards for his outstanding achievements and contributions to promote public health, which include FDA’s “Outstanding Service Award” (2014 and 2017), NCTR’s “Outstanding Service Group Award” (2014), NCTR’s “Special Act Award” (2014 and 2017), and NCTR’s “Outstanding Junior Investigator Award” (2016). In addition, Dr. Vijay has served as chair in several platform and poster sessions as well as peer mentor for the Undergraduate Education Program at Society of Toxicology meetings and supervisory mentor for undergraduate students in summer student research program at NCTR.


Research Interests

The overall goal of Dr. Vijay’s research is to safeguard public health by reducing harm from unsafe agents and to promote personalized medicine by discovering new biomarkers and understanding their role in the causation of drug-induced toxicity. Dr. Vijay is an expert in developing and utilizing diverse computational approaches to integrate, analyze, and interpret toxicological and omics data. For more than a decade, his research has been focused on advancing predictive-toxicology and precision-medicine efforts. He has made significant contributions to these fields by developing QSAR (Quantitative Structure Activity Relationship) models to predict dermal toxicity of biocides in occupational workers during his doctoral research. He has also built a liver toxicity knowledge base to help predict drug-induced liver injury during his post-doctoral research. Dr. Vijay’s ongoing research aims to identify omics biomarkers from in vivo tests that may predict occurrence of adverse effects in response to drugs such as doxorubicin in certain individuals or subpopulations and molecular biomarkers that may predict age- and sex-related susceptibilities to drug toxicities.

Drugs are developed with an aim to treat disorders and significant effort is invested to make them effective, as well as safe. While most of the patients have favorable outcomes with mild side effects, a minority of them develop serious or severe drug-induced adverse events. The reason for developing these adverse events in certain individuals can be diverse, and may be attributed to differences in genetics (molecular makeup), the way body interacts with drugs, physiological conditions, nutrition, sex, age, body composition, polypharmacy, environmental conditions, lifestyle habits, etc.

Any one or more of these aforementioned factors can cause different molecular events leading to adverse effects. An investigation of these molecular events has resulted in many predictive and diagnostic biomarkers and has improved our understanding of the toxicity mechanisms for several drugs. Therefore, Dr. Vijay’s current projects focus on using omics data to understand target organ susceptibility and possible age and/or sex differences to doxorubicin and two other classes of drugs, namely, tyrosine kinase inhibitors and drugs that affect mitochondria.

These are important regulatory science projects with major applications in FDA’s efforts to assure safe and effective drugs.
