Dr. Devendra Kumar is currently a Postdoctoral Fellow of the Department of Pediatrics, Division of Hematology/Oncology, University of Nebraska Medical Center, Omaha, NE 69198, USA. He has specialized in multidisciplinary biomedical research, has in-depth knowledge of drug discovery, and understands the mechanisms involved in absorption, distribution, metabolism, and excretion (i.e., pharmacokinetics, PK) of these agents and how both the PK and pharmacodynamic (PD) effects of these agents are altered by genetic differences (polymorphisms) between individuals (i.e., pharmacogenetics, PG). He is actively involved in bioanalysis with multiple operational assays including in vitro chemical and metabolic stability, metabolite identification, protein binding, permeability assessments, and transporter assays to characterize new drug molecules.
