Ashwani Kumar (scientist)

Ashwani Kumar is an Indian microbiologist and the Senior Principal Scientist at the Institute of Microbial Technology (ImTech). He is known for his studies on Mycobacterium tuberculosis, the causative agent of tuberculosis. His laboratory focuses on understanding the reasons for drug tolerance observed in humans. His laboratory hypothesizes that tuberculosis is a biofilm infection, so its treatment needs the administration of multiple drugs for at least six months. The Department of Science and Technology has awarded him Swarnajayanti Fellowship for 2016–2017. Department of Biotechnology has awarded him the National Bioscience Prize (2017-18). He was also selected for DBT/Wellcome Trust India Alliance Senior Fellowship (2021 to 2026). He was elected as a Fellow of the National Academy of Sciences, India, in 2022. For his contributions in tuberculosis pathogenesis, he was awarded with Shanti Swarup Bhatnagar Prize for Science and Technology 2022. He is considered as one of India's Leading Scientist in the field of Tuberculosis and his lab is doing some of the best research in India.
