Profile
Dr. Rituraj Niranjan is currently working as Scientist-D in the area of immune system associated disorders. By training he is cellular and molecular immunologist. Beside cellular and molecular immunology research, he is engaged in the different immune system associated disorders like, immunopathogenesis of DENGUE fever, mechanisms of immune dysfunctions in other vector borne diseases, allergy and immunology, tissue remodelling and fibrosis, autophagy, acute kidney failure, neuroinflammation, nanoparticle-based drug delivery system and immuno-compromise disorders. Dr. Rituraj Niranjan work focuses on the role of Interleukin-15 (IL-15) in the lungs, gastrointestinal and other immune disorders. He has done his Ph.D. degree from Jawaharlal Nehru University, New Delhi, in the area of immuno-neuropharmacology working at the CSIR-Central Drug Research Institute (CDRI), Lucknow, India. He completed his first post-doctoral fellowship from University of Arkansas for Medical Sciences, Little Rock, USA and then did his second post-doctoral fellowship from Cincinnati Children Hospital and Medical Research Centre, Cincinnati, Ohio, USA and latter at the Case Western Reserve University, Cleveland USA. Before joining to the Indian Council of Medical Research as a talent search scientist (TSS-ICMR), he was working as scientist at the Indian Institute of Technology, Kanpur (IIT-K), India.
