I obtained my medical degree from the University of the Philippines. I completed a residency in Internal Medicine at the Sinai Hospital of Baltimore affiliated with the John Hopkins University Medical School in Baltimore, MD before coming to New Haven where I trained as a post-doctoral fellow in infectious disease, epidemiology and medical microbiology.
I began my professional career in New Haven, CT at the Cornall Scott-Hill Health Center as a medical director (1998-2001). Later I jointed the Infectious Disease service at the Hospital of Saint Raphael (2001-2012) and finally the Northeast Medical Group (2012-2014) before becoming a faculty member at Yale. I am based at the Saint Raphael Campus of YNHH.
I have particular interest in helping people who have been affected by HIV/AIDS. I am the medical director of HIV Services at YNHH-Saint Raphael Campus and director of the Haelen-Infectious Disease Center. The work I do focuses on the continuum of HIV care from diagnosis, linkage, retention and optmizing outcomes. I am also involved with the HIV Prevention Program at YNHH and with the state of CT. I have an interest in general infectious diseases particularly with MRSA bloodstream infections and other hospital-acquired infections. I am the principal investigator for a number of Clinical Trials that permits patients access to newly formulated antimicrobials.
