Dr. Gregory Marcus is a specialist in the treatment of arrhythmias, including mapping and catheter ablation for atrial fibrillation, supraventricular tachycardias and ventricular arrhythmias. He is also an expert in pacemaker, biventricular device and defibrillator implantation.
Dr. Martin is Professor and Chief of the Division of Clinical Epidemiology and Health Services Research in the Department of Epidemiology and Biostatistics at the University of California, San Francisco (UCSF). His clinical training is in internal medicine and infectious diseases, and he has served as attending physician at the San Francisco General Hospital HIV/AIDS program clinic. He is formally trained in clinical and epidemiologic research methods at UC Berkeley, where he earned a master of public health degree with concentration in epidemiology.
My research focuses on fundamental questions in the tracking and early identification of drug-resistant tuberculosis (DR-TB) to better target and evaluate control interventions. I have specialized training in clinical research methods, statistical prediction, repeated measures, and causal inference through doctoral work in the Division of Epidemiology, UC Berkeley. I have served as a consultant to the WHO, USAID, and PAHO for the development of regional and national TB management guidelines.
Dr. Payam Nahid, the Haile T. Debas Distinguished Professor of Global Health, is the Executive Director of the UCSF Institute for Global Health Sciences.
Despite nearly three decades of focused research since the discovery of HIV-1, to date there is no cure or effective prophylactic vaccine for HIV-1 infection. Although the advent of Highly Active Antiretroviral Therapy (HAART) has dramatically decreased the morbidity and mortality associated with HIV-1 infection, there is a pronounced demand for alternative clinical management strategies due to frequent evolution of antiretroviral resistance, toxicity, and access constraints in resource-limited settings.
The Roan Lab studies how intracellular and extracellular factors in the tissue microenvironment can affect infection by HIV, mucosal immunity, and reproductive health. We have demonstrated that genital and rectal fibroblasts, amongst the most abundant cells of the mucosa, potently increase HIV infection of T cells through at least two distinct mechanisms: promoting viral entry, and altering the cellular state of T cells to render them more permissive to viral replication.
Dr. Tien is Professor of Medicine at the University of California, San Francisco and Chief of the Infectious Diseases Division at the San Francisco Veterans Affairs Health Care System. Her research program examines the mechanisms by which chronic viral infections (specifically HIV and HCV) and their associated metabolic and immune perturbations impact long term organ injury in adults.
Zian H. Tseng, M.D., M.A.S., a cardiologist and a cardiac electrophysiologist, joined the faculty in 2004, bringing expertise in risk stratification of patients prone to sudden death and ventricular arrhythmias. Dr. Tseng, a Bay Area native, is an alumnus of the UCSF School of Medicine, where he also completed a year of graduate studies in Biomedical Sciences and a Master's in Advanced Studies in Clinical Research. He completed his clinical training in internal medicine, cardiology, and cardiac electrophysiology at UCSF.

I am a pulmonary and critical care medicine specialist with a research focus on pulmonary diseases affecting persons with HIV with a global perspective. I am a clinical-translational researcher with clinical cohorts in San Francisco, CA and in Kampala, Uganda.
Professional Experience: Dr. Hsue trained in Internal Medicine in the Molecular Medicine Training Program at UC San Francisco and in Cardiovascular Medicine at UC San Francisco. She served as Chief Cardiology Fellow during this time. She has been on the faculty in the Department of Medicine at San Francisco General Hospital since 2002. She started the HIV Cardiology Clinic since March 2004 at the Positive Health Program at Ward 86, which is one of the first subspeciality clinics of its kind in the nation.
