Alex Kleinpeter earned his Ph.D. in biochemistry and structural biology from the University of Alabama at Birmingham in Dr. Chad Petit’s lab.  He is characterizing the role of the small-molecule metabolite inositol hexakisphosphate (IP6), a critical host cofactor in HIV-1 replication, in facilitating the formation of the immature HIV-1 Gag lattice and mature capsids.  Alex was awarded Intramural AIDS Research Fellowships from NIH in 2021 and 2020 to support his research, and he won a travel award for his outstanding presentation at the Fall HIV/AIDS & Cancer Think Tank Meeting.  In 2023, Alex successfully competed for a K99/R00 Pathway to Independence (PI) Award from the NIH.
