Biography
Dr. Pradeep Uchil is Associate Professor in the Department of Microbial Pathogenesis at Yale University. He received his PhD in Molecular Virology at the Indian Institute of Science, Bangalore, India, where he elucidated the architecture of flavivirus replication complexes. He completed his postdoctoral studies at Yale University with Prof. Walther Mothes in Retrovirus Cell Biology and Innate Immunity. Dr. Uchil studies how viruses replicate, spread, and interact with hosts to cause disease using mouse infection models. He has expertise in innate immunity, viral immunology, and elucidating virus-host interactions using imaging-based approaches that span multiple scales of resolution from the whole body to the ultrastructure. Specifically, he utilizes noninvasive whole-body bioluminescence imaging (BLI) as an unbiased guide for the identification and in-depth characterization of key tissues and physiologically relevant cell types that contribute to virus spread, pathogenesis, and immune control. He is well recognized for his expertise in imaging and its application to uncover both fundamental and translational aspects of virus infection in mouse models.
