Tahir A Rizvi

Professor and PI in Rizvi Lab

Prof. Tahir A. Rizvi obtained his doctorate (PhD) degree from the All India Institute of Medical Sciences (AIIMS), New Delhi, India, 1987 focusing on aflatoxin-induced liver carcinogenesis. He did his postdoctoral training at the McArdle Laboratory for Cancer Research, University of Wisconsin-Madison, USA, initially in liver carcinogenesis and later in retroviral replication. He was appointed as an Assistant Professor at the MD Anderson Cancer Center, Texas, USA in 1992. In 1997, he was promoted to the rank of Associate Professor and in 2001 joined the Department of Microbiology & Immunology, College of Medicine, and Health Sciences (CMHS) at UAE University in Al Ain. In 2006, he was promoted to the rank of full Professor. He served as the Director of Zayed Bin Sultan Al Nahyan Center for Health Sciences (ZCHS), UAE University from 2020-2025.

Over the last 3 decades, the focus of Prof. Rizvi’s research has been to elucidate the basic steps in retroviral replication with the ultimate goal of developing improved retroviral vector systems for human gene therapy. The current focus of research in his laboratory is on how retroviruses package their genomic RNAs into virus particles and what are some of the underlying differences in RNA packaging among different retroviruses, including including human, simian, and feline immunodeficiency viruses (HIV, SIV, & FIV), Mason-Pfizer monkey virus (MPMV), and mouse mammary tumor virus (MMTV). . His studies on RNA packaging have been published in journals of international repute, including Nucleic Acid Research, PLoS Biology, Journal of Molecular Biology, RNA, etc. Prof. Rizvi has successfully competed for both intramural and extramural grants, including the prestigious Wellcome Trust grant. More recently, this expertise has been applied to SARS-CoV-2, including biomarker discovery, vaccine effectiveness, and novel detection technologies. In parallel, he has served and continue to serve on the editorial boards of leading journals, including Journal of Virology, Scientific Reports, Retrovirology, and npj Viruses, reflecting sustained international engagement and recognition.
