Amit Singh (born 18 March 1976) is an Indian microbiologist in the Department of Microbiology & Cell Biology at the Indian Institute of Science. His primary research area is pathogenesis, with a focus on drug resistance mechanisms in both mycobacterium tuberculosis (TB) and human immunodeficiency viruses (HIV).

Amit Singh was born on the 18 March of 1976.^[1] He obtained a Bachelor's degree in Science from the University of Delhi, and a Master's degree in Biotechnology from Indian Institute of Technology Roorkee in 1998.^[2] In 2004, he completed a PhD under the supervision of Anil Kumar Tyagi at the South Campus and subsequently moved to the US for postdoctoral training at the University of Alabama in Birmingham in the laboratory of Dr. Adrie J.C. Steyn.^[3]

Upon his return to India in 2010, Singh was a Wellcome Trust-DBT Intermediate Fellow at the International Centre for Genetic Engineering and Biotechnology. In January 2014, he joined the Indian Institute of Science (IISc) in their department of microbiology and cell biology, where he is currently an associate professor.^[4] He is the group leader at the Centre for Infectious Disease Research,^[5] where researchers^[6] are investigate the mechanisms of chronic human infections with a focus on Mycobacterium tuberculosis and human immunodeficiency virus (HIV).^[7][8]

Singh has been a Welcome Trust-DBT Senior Fellow since 2016.^[9][10] He received the 2017/18 National Bioscience Award for Career Development from the Department of Biotechnology of the Government of India.^[11]

In 2021, Singh was awarded the Shanti Swarup Bhatnagar Prize for Science and Technology for his contributions to understanding host-pathogen interactions in Mycobacterium tuberculosis and HIV.^[12] In 2022, Singh was included in the Asian Scientist 100 list.
