Nafees Ahmad

Professor

Dr. Nafees Ahmad received his BS (Hons) in Chemistry and MS in Biochemistry from one of the prestigious central universities in India, The Aligarh Muslim University. He then joined another renowned research institute, The Central Drug Research Institute, Lucknow, India, from where he earned his Ph.D. in 1983.  Dr. Ahmad did his Postdoctoral Fellowship at the National Institutes of Health (NIH), Bethesda, Maryland, USA from 1985-1990 in the Laboratory of Molecular Microbiology, National Institute of Allergy and Infectious Diseases. His research primarily focused on the regulation of HIV-1 gene expression and replication, especially the role of HIV-1 regulatory and accessory proteins in HIV-1 replication and biology.  In 1990, a group of scientists from the NIH, including Dr. Ahmad moved to J.N. Gamble Institute of Medical Research, Cincinnati, Ohio to start a new program on Molecular Virology, including his own independent research program on molecular mechanisms of HIV-1 mother-to-infant transmission. In 1994, Dr. Ahmad joined the University of Arizona College of Medicine – Tucson’s Department of Microbiology and Immunology (now Immunobiology). His research involves understanding the molecular mechanisms of differential HIV infection in infants and adults and vertical transmission and pathogenesis. In addition, he directs the Immunity and Infection block of the medical curriculum of the College of Medicine – Tucson.
Teaching
Dr. Ahmad's major teaching responsibilities include serving as the director, instructor and facilitator of the Immunity and Infection (I&I) block (MED 822, 9 units) for 110-120 second year medical students. In addition, I serve as a facilitator in several other blocks, including Prologue (MED 814, 2 units), DMH (MED-820, 14 units), Life Cycle (MED-821, 9 units), and Advanced Topics (MED-823, 9 units) of the College of Medicine – Tucson. Immunity and Infection Block covers multiple disciplines, including Immunology, Virology, Bacteriology, Mycology, Parasitology, Adult and Pediatric Infectious Disease, Pathology, Pharmacology, Nutrition, Bioethics, Bioterrorism, Humanisms and Global, National & Local Public Health and various departments such as Immunobiology, Pathology, Pharmacology, Medicine, Pediatrics, Physiology, Cell Biology & Anatomy, Nutrition, Family and Community Medicine and Public Health.
At the graduate level, he teachs a 3-unit Molecular Virology (IMB 580) course to graduate students. He also direct a 3-unit Graduate Medical Microbiology (IMB-510) Course as well as teach the Virology section of this course. Furthermore, he supervises medical, undergraduate and graduate students for research in his laboratory.
Dr. Ahmad has received several awards and recognition for teaching at the University of Arizona.

Research 
Molecular Virology
The main focus of Dr. Ahmad's laboratory is to understand the molecular mechanisms of differential HIV-1 infection in neonatal and adult target cells as well as HIV-1 vertical transmission. Areas of investigation include: role of viral and host factors associated with a higher viral load and rapid AIDS progression in neonates/infants compared with adults; identification and characterization of host factors influencing differential HIV-1 infection and gene expression in neonatal (cord) blood mononuclear cells vs. adult cells; role of HIV-1 integration in differential HIV-1 gene expression and replication in cord vs. adult cells; mechanisms of differential HIV-1 infection in neonatal macrophages and naïve/memory T-cells vs. adult cells; molecular and biological characterization of HIV-1 involved in vertical transmission and disease progression; viral determinants, including viral heterogeneity, functional conservation/divergence of various HIV-1 genes, presence/absence of motifs in HIV-1 genes, replication efficiency, cell tropism, cytopathic effects, and coreceptor utilization associated with HIV-1 maternal-fetal transmission and pathogenesis; development and evaluation of anti-HIV-1 agents, including HIV entry inhibitors and inhibitors from natural products.
