Major Contributions to Science


The Center for Therapeutic Development at BIIR is committed to developing novel therapies and biomarkers for cancer, infectious disease and autoimmune disease, discovered at BIIR. Our most advanced therapies are dendritic cell targeting vaccines for treatment of HIV injection, HPV-related cancers, and multiple sclerosis. Working with numerous other groups at BIIR and BRI, I am leading the efforts to bring these vaccines through preclinical development and into critical Phase 1 clinical trials at Baylor Scott & White.


Prior to joining BIIR, I was a principal scientist at Alcon Laboratories, a division of Novartis, from 2005 to 2012, where I headed a laboratory focused on drug discovery for allergic and inflammatory conditions of the eye. I also was a project team leader of early stage discovery efforts, bringing several new therapies into the development stage for proof-of-concept clinical trials.  


My graduate and postdoctoral work examined the role of inflammation in dry eye disease and corneal transplant rejection. One of my major contributions was the identification of a new pathway of Th2 cell-mediated corneal allograft rejection in a mouse model in which the transplant recipients had allergic conjunctivitis. This finding was paradoxical to conventional wisdom that immune allograft rejection was due solely a Th1-mediated response and that a Th2 response would be tolerogenic.
