# Shrawan Kumar (geneticist)

Shrawan Kumar, is an Indian-American geneticist, working in the fields of molecular and population genetics. He contributed to the discovery of two genes related to Branchio-oto-renal syndrome (BOR) and Autosomal Dominant Polycystic Kidney Disease (ADPKD2).

## Career

Following the completion of his M.S. and Ph.D. in India, Shrawan Kumar joined the University of Nebraska Medical Center as a Postdoctoral Fellow in Omaha, Nebraska, USA, in 1988. Subsequently, he contributed to genetic research at the Boys Town National Research Hospital, which is affiliated with Creighton University Medical Center, holding positions as Associate Professor and Staff Scientist where his research initiatives were related to the exploration of genes associated with hearing loss and kidney disorders. Later, he served as the principal investigator on a National Institutes of Health-funded research grant, which led to the discovery of two genes viz. Branchio-oto-renal syndrome (BOR) and Autosomal Dominant Polycystic Kidney Disease (ADPKD2). He was also involved in the discovery of an additional gene linked to branchio-otic (BO) type syndrome, located on chromosome 1q31. His contributions are documented in OMIM, (Online Mendelian Inheritance in Man), a comprehensive catalog of human gene discoveries and genetic disorders.
Kumar, whose efforts are also associated with the Native-American communities, serves at the Munroe Myer Institute at the University of Nebraska Medical Center. where he is involved in guiding students on career pathways associated with basic science and cancer education He also participates in various workshops and consortia related to the human genome project, notably in several International Workshops on Human Chromosome 8 Mapping.
