Larry Grill

Larry Grill, PhD is a Research Professor at Keck Graduate Institute (KGI) and holds an adjunct appointment in the Department of Natural Sciences at The Claremont Colleges. He has been with KGI since 2013, previously serving as Dean of Research until 2023. His primary affiliation is with the Riggs School, though teaching responsibilities span multiple institutions.

Dr. Grill earned his PhD in 1979 from the University of California, Riverside. As a pioneer in plant-based biotechnology, his work focuses on developing low-cost vaccines and therapeutics using viral vector systems. Key areas include vaccines for animal diseases impacting African agriculture and prophylactic treatments for viral infections like rabies and SARS-CoV-2.

His career includes co-founding Large-Scale Biology Corporation (LSBC), which advanced plant-based production of therapeutic proteins and vaccines. Notable achievements include successful clinical trials for patient-specific lymphoma vaccines and multi-kilogram-scale production of pharmaceutical proteins through plant viral expression systems.

With over 25 publications and 30 patents, his research emphasizes practical applications of biotechnology for global health challenges. Current efforts combine virology, immunology, and agricultural science to create scalable solutions for infectious disease prevention.
