Biography

[edit]

Umesh Varshney, born on 26 October 1957 in the Indian state ofUttar Pradesh,graduated in science fromJiwaji Universityin 1975 and completed his master's degree atG. B. Pant University of Agriculture and Technologyin 1979.[4]Moving to Canada, he did his doctoral studies on a Graduate Teaching Assistantship and Studentship by Alberta Heritage Foundation for Medical Research Foundation (AHFMR) under the guidance of Lashitew Gedamu and secured his doctoral degree from theUniversity of Calgaryin 1985. His post-doctoral studies were at the laboratory of Johan Hans van de Sande at the university and, later, atMassachusetts Institute of Technologywith U. L. RajBhandary. Returning to India in 1991, he started his career at the Department of Microbiology and Cell Biology (then known as Centre for Genetic Engineering) of theIndian Institute of Scienceas an assistant professor, and promoted to associate professor (1997), professor (2002) and dean of the undergraduate programs[6]and heads a laboratory[7]while chairing the Department of Microbiology and Cell Biology of the Indian Institute of Science.[8]He is also an honorary faculty atJawaharlal Nehru Centre for Advanced Scientific Researchsince 1999[9]and is a collaborator of the Genome Metabolism and Biostruct Laboratory, Budapest.[10]He is currently the Chairman of the division of Biological Sciences at the Indian Institute of Science, Bengaluru.

Legacy

[edit]

Varhsney's researches are primarily focused in the area of protein synthesis and DNA repair inEscherichiacoliandMycobacterium tuberculosis.[11][12]His researches are known to have assisted in a wider understanding of the biology of mycobacterium, more specifically the interaction between ribosome recycling factor and elongation factor G as well as theuracilexcision repairpathway.[13]These studies are reported to have been aimed at developing newer drug targets and the attenuated strains.[4]He has detailed his research findings by way of articles published in peer-reviewed journals[note 1]and online scientific article repositories likeResearchGate,Google Scholarand PubFacts have listed many of them.[14][15][16]He was one of the organizers of the 21st International tRNA Workshop held at Indian Institute of Science in December 2005, has guided several scholars in their doctoral researches[4]and delivered keynote addresses at many science conferences.[17][18]

Awards and honors

[edit]

In 1999, when theDepartment of Biotechnologyof India instituted theNational Bioscience Award for Career Developmentas one of the prestigious science awards in the country,[19]Umesh Varshney was among the first recipients of the award.[20]TheCouncil of Scientific and Industrial Researchawarded him theShanti Swarup Bhatnagar Prizein 2001, and then in 2014 he was awarded the G. N. Ramachandran Gold Medal for Excellence in Biological Sciences & Technology. In 2001, he received the P. S. Sarma Memorial Award of the Society of Biological Chemists (India) (SBC.[21]A life member of the SBC, he received the Life Sciences Research Award ofNovo NordiskEducation Foundation in 2002 and the year 2008 brought him the elected fellowship of theIndian National Science Academyand the J. C. Bose National Fellowship of theDepartment of Science and Technologyof India.[4]
