Title: Post-Doctoral Associate

Phone: 305-348-4857


Department(s): Immunology and Nano-Medicine

Dr. Mohan has obtained his Ph.D. in Pharmacology from Banaras Hindu University, Varanasi, India in 2007. He joined this department as post-doctoral associate during 2017. Previously, he has worked as Postdoc at Loma Linda University, Loma Linda, CA, USA. Dr. Mohan also has experience in working with pharmaceutical industry (Drug discovery) in India, before coming to USA. His current research is focused on animal models of Zika virus to understand the pathophysiology of Zika virus infection/transmission to fetus from pregnant mother. He is trying to explore the possible role/impact of autophagy in Zika virus infection using Beclin1 knockout autophagy mouse model. Dr.Mohan is also working on gender differences in HIV associated neuropathic pain in HIV animal model. He has developed an interest to do research on influence of autophagy on wound healing in HIV animal model. His research also includes Intranasal delivery of Nanotherapeutics for HIV attenuation in animal model.
