Dr. Khan has completed PhD at ICGEB/JNU (2015) on the HIV-1 virus; he accepted a Post-Doctoral Fellow position in the School of Medicine and Health Sciences at the University of North Dakota USA where he remained working for almost five years (2015). The focus of his research continues to be on the HIV-1-Associated Neurocognitive Disorders (HAND) by emphasizing the roles of HIV-1 proteins in the development of HAND. Currently, his research works are related to the following projects: (1) Tat endolysosome escape. This project’s primary goal is to test the hypothesis that HIV-1 Tat escapes endolysosomes through protein pores of the membrane sector (V0) of v-ATPase, and that this escape is facilitated by calcium release from endolysosome two-pore channels (TPCs), and that all of this contributes to Tat-induced neurotoxicity. (2) Identifying the protective actions of Trehalose and Ketone bodies on the HIV-1 Tat-induced neurotoxicity.

He has extensive experience in handle the BSL3 laboratory. During his PhD period, he trained and taught many students to handle the BSL3 laboratory. Since Dec 2015, as a Post-Doc, He trained five undergraduate and 4 PhD students and supported their research work. He is an academic editor at three different international peer-review journals. He has published 15 manuscripts and presented his research work at six different places worldwide. His publications have been cited over 175 times as Google scholar citations. Also, he got the first prize for a poster presentation on my research work at the SNIP meeting, Philadelphia-USA.
