Dr. Perez's laboratory focuses primarily on researching immunology of corneal transplantation and ocular Graft vs Host Disease (GVHD). Dr. Perez and his colleagues use a mouse model of corneal transplantation and Ocular GVHD that allows for translational research relevant to patients with penetrating keratoplasty and ocular GVHD. Dr. Perez's grant from the National Eye Institute supports his lab's work on the immunological mechanisms involved in high-risk corneal transplant rejection and ocular GVHD.
