Sunil David received his M.D. and Ph.D. degrees from the Christian Medical College in Vellore, India. Following postdoctoral training stints at the Forschungszentrum, Borstel, Germany, Indian Institute of Science, Bangalore, and the University of Kansas Medical Center, he joined the faculty at KU before being recruited by the Department of Medicinal Chemistry at the University of Minnesota. His research focuses on the discovery and development of endotoxin-sequestering molecules as potential anti-sepsis agents, modulation of innate immune pathways, and host responses to infectious agents.
