Profile Summary

An accomplished molecular virologist trained at the Massachusetts Institute of Technology with 15+ years of discovery and preclinical research experience for prevention of emerging viral infections including Flavi (Dengue, Zika, Yellow Fever), Bunya (Rift Valley), HIV, Herpes, Parvo, Corona and Influenza virus. A subject matter expert in the areas of virology, immunology, neuroscience, biodefense and infectious diseases, is well-known for his leadership skills in laboratory technology, microbial characterization and safety/toxicology evaluation of antivirals and vaccines. He is particularly known for drug development strategy, team management and strong collaborations with various stakeholders including CROs, clinical operations and FDA regulatory affairs. At CONRAD, he played a leading role to obtain multi-million dollars funding, and to advance a number of antivirals (TMC120, UC781, MIV150) to clinical trials. He was a competent reviewer of NIH grant proposals, and was selected for the distinguished researcher award by Sigma Xi Society.
