Sunil Ahuja, M.D.



Dr. Sunil Ahuja oversees an inter- and multi-disciplinary research program at the university and the Center for Personalized Medicine at the Veterans Administration hospital that links state-of-the-art genomic, immunologic and molecular technologies with epidemiology, clinical, and animal research to identify the determinants of human diseases such as HIV, allergy, and autoimmunity.
