Saurabh’s research interests include study of the gastrointestinal immune system in HIV infection. He trained at the Aaron Diamond AIDS Research Center in the laboratory of Dr. Martin Markowitz where he described the early and preferential depletion of GI CD4+ T cells during acute HIV infection and the incomplete reconstitution of intestinal CD4 T cells with ART. Saurabh then worked in the laboratory of Dr. Ralph Steinman, where using novel HIV vaccines, he focused on the generation of intestinal immunity against HIV.
