I am a physician-scientist in Northern California. My lab investigates the pathophysiology of autoimmunity, how T cells (a type of white blood cell) develop and mature, and cancer immunotherapy. We are also interest in how foods interact with our immune system; how the immune system recognizes cancer, especially melanoma; developing novel hydrogels for delivering stem cells and immunotherapeutics; clinical trial design, and outcome measures. Some diseases of special interest include psoriasis, scleroderma, pyoderma gangrenous, pemphigus vulgaris, bullous pemphigoid, melanoma, and cutaneous T cell lymphoma.
