Research Focus

Dr. Kumar’s research focuses on the development and application of induced pluripotent stem cell (iPSC) based methodologies and cell models to identify genetic and environmental determinants of human disease risk. He has developed an efficient iPSC reprogramming methodology for cryopreserved lymphoblastoid (immortalized B lymphocytes) cell lines (LCLs). This cost effective and highly successful reprogramming methodology has potential to have a significant impact in the field because numerous sample repositories worldwide have banked LCLs that could be used for iPSC generation. Dr. Kumar’s laboratory has generated more than 300 validated iPSC lines using one such LCLs repository maintained in the Department of Human Genetics and at the STDOI for its longitudinal Mexican American Family Study. The generated iPSCs and the protocols that Dr. Kumar has developed are being used in in-vitro modeling of disease related phenotypes in genetic studies of neurodegenerative and neuropsychiatric disorders, metabolic disorders including type 2 diabetes, cardiovascular disease, obesity, and fatty liver disease and more recently in understanding individual variation in cellular response to SARS-CoV-2 infection.

In a recent NIH funded project, Dr. Kumar has developed iPSC reprogramming and differentiation methodologies for Monodelphis domestica. The generated iPSCs are the first integration free and the second ever reprogrammed from a marsupial species. M. domestica is a well-established laboratory animal that is used as an experimental model in many basic, comparative, and biomedical research applications.

Apart from his current endeavor in developing iPSC methodology, Dr. Kumar has had a major role in several large-scale, NIH and industry funded, human genetics projects, aimed at identifying genes influencing human complex diseases. He also has a strong interest in human phylogenetics, mitochondrial DNA variation and mitochondrial retrograde regulation - a process that is likely to have far-reaching implications in development, aging, disease, and environmental adaptation.
