Dr Suraj Parihar

• Bio Sketch

Suraj Parihar is an immunologist with research focuses on understanding macrophage-pathogen interactions. He aims to identify host factors/products, exploited by intracellular pathogens such as M. tuberculosis and L. monocytogenes to survive and/or evade macrophages killing functions.


• Research Interests

His research focuses on host-directed therapies with the potential of translation in humans. To this end, he uses deep-CAGE transcriptomics, repurposed drugs or chemical inhibitors, gene knockdown as well as gene-deficient murine models.
