Dipika Gupta, PhD

Associate Professor of Biochemistry and Molecular Biology


Dr. Gupta is an Associate Professor of Biochemistry and Molecular Biology at Indiana University School of Medicine. Her research has discovered a new family of innate immunity proteins and identified their role in the regulation of microbiome, host-bacterial interactions, and development of inflammatory disease, including obesity and colitis. These discoveries enhance our understanding of the host-microbe interactions and their role in pathogenesis and will also pave the way for the development of new approaches for the prevention and treatment of inflammatory diseases. Dr. Gupta is the course director and a lecturer for the course Molecules to Cells and Tissues taught to first-year medical students.
