Rohan Dhiman

Rohan Dhiman is Associate Professor in the Department of Life Science at Rourkela, Odisha, India. He completed his Ph.D. at Institute of Microbial Technology, Chandigarh before moving to University of Texas Health Science Centre at Tyler for post-doctorate training. After four years there with virulent mycobacteria to study the role of NK cells, regulatory T-cells and monocyte heterogeneity in tuberculosis, he returned to India and joined as a Research Scientist in Translational Health Science and Technology Institute where he started studying different facets of pathways related to autophagy and post-translational modification regulated by mycobacterium in infected macrophages. After joining in current institute in 2014, he started his independent lab and currently focusing on screening some libraries w.r.t. autophagy induction ability of the molecules and Calcimycin is one of the compounds that his lab found through this approach. He has published 35 papers till now and co-authored different book chapters.
