Sreetama Choudhury, PhD

Postdoctoral Fellow

As a post-doctoral researcher in the Subramanian lab, I am working to understand the mechanisms of host-pathogen interaction. I specifically study the immune evasive strategies developed by pathogens to subvert the host immune system to establish disease focusing on the intracellular pathogens Mycobacterium tuberculosis and Salmonella typhimurium. We combine experimental and computational data to dissect the complex crosstalk between the host and the pathogen. I am presently developing a systems-based approach to identify critical mediators at the transcriptional level that may act as potential targets for development of host-directed therapies. I am also a recipient of the 2020 AAI Career Re-entry award. Besides research I love cooking and travelling.
