Background

Dr. Shraddha Thakkar received a master’s degree and Ph.D. in bioinformatics from the University of Arkansas at Little Rock/University of Arkansas Medical Sciences, Joint Bioinformatics program. She specialized in macromolecular crystallography, cheminformatics, and structural biology. Prior to that Dr. Thakkar received an MSc. in biotechnology from Bangalore University, India. She holds 14 international patents and multiple publications in area of drug development for radiation protection, predictive toxicology, leukemia, and atherosclerosis. Her current area of research includes development of methods and classifications to enhance the understanding and prediction of drug-induced liver injury (DILI).

Dr. Thakkar has adjunct appointments at both the University of Arkansas for Medical Sciences and the University Arkansas at Little Rock (Assistant Professor). She was elected as board member of the Mid-South Computational Biology and Bioinformatics Society (MCBIOS) in 2014 and served as president of MCBIOS from 2016-2017. She also served as the chair of 1) Pharmacogenomics Group of the American Association of Pharmaceutical Scientist (AAPS) and 2) Personalized Medicine community at AAPS. Dr. Thakkar has received multiple research and leadership awards regionally and nationally and within FDA including the AAPS “Genentech Innovation in Biotechnology Award,”  the American Crystallography Association’s “Margret C. Etter Student Lecturer Award,” and FDA’s “Outstanding Service Award.”
 

Research Interests

Dr. Thakkar’s research interests are in applying bioinformatics and cheminformatics for study of toxicity and drug development with specific interest in DILI. Dr. Thakkar has working in drug development, drug safety, pharmacogenomics/toxicogenomics, personalized medicine, predictive toxicity, and DILI. Her current research includes:

  • Managing and further developing the cheminformatics infrastructure for Liver Toxicity Knowledge Base (LTKB) for study of DILI.

  • Developing predictive toxicological models for DILI for preclinical toxicology.

  • Benchmarking and comparing computational and genomic predictive methods for toxicity.
