Gavin McStay received his Ph.D. from the University of Bristol, UK, with Professor Andrew Halestrap studying the molecular composition of the mitochondrial permeability transition pore involved in cell death. I performed post-doctoral research with Dr. Douglas Green at the La Jolla Institute for Allergy & Immunology in San Diego, Calif., and St. Jude Children's Research Hospital in Memphis, Tenn., studying apoptosis, especially the role of mitochondria and caspases. Following, this he worked with Professor Alexander Tzagoloff at Columbia University studying assembly of cytochrome oxidase in budding yeast before moving to NYIT. McStay is continuing these areas of research to gain an understanding of fundamental processes in cells with the hope that the findings can make an impact in biomedical and biotechnological research.
