Assistant Professor of Medicine (Gastroenterology and Hepatology)

Inflammatory bowel disease (Crohn's disease and ulcerative colitis), therapeutic drug monitoring, clinical trials

Sergejs Berdnikovs

Associate Professor of Medicine (Allergy and Immunology)

The question of primary interest in my lab is why only select individuals, despite being genetically similar and living in the same allergen environment, are prone to developing allergic disease, and which processes drive this predisposition? To address this, we employ a systems biology approach and bioinformatics to explore whether there is underlying unity in the pathogenesis of seemingly disparate allergic diseases. By synthesizing large volumes of biological data, we link departures from homeostatic conditions (including changes in metabolic, developmental, and endocrine systems) at the ep...

Kush Desai

Associate Professor of Radiology (Vascular and Interventional Radiology), Medicine and Surgery (Vascular Surgery)

My primary research and clinical interests are in venous thromboembolic disease, including IVC filter management/complex IVC filter retrieval, deep venous thrombolysis, reconstruction of chronic venous occlusions, and interventional pulmonary embolism management. I have additional clinical and research interest in hepatobiliary disease, including liver directed therapies for hepatocellular carcinoma, management of portal hypertension, and biliary disease.

Eric W Terman

Clinical Assistant Professor of Medicine (General Internal Medicine and Geriatrics)

I have been deeply involved in medical decision making from the perspective of psychological and fact driven decisions. I enjoy nearly all aspects of managing general medical problems from cholesterol to autoimmune disease to travel medicine... I try to maximize my patients health and quality of life.

Stuart Rich

Professor of Medicine (Cardiology)

Dr. Rich has a career interest in understanding the causes and treatments of pulmonary hypertension. He was principle investigator for the NIH Registry on Primary Pulmonary Hypertension, the first of its kind, and has been the leader of the largest clinical center in the USA for evaluating and treating patients with pulmonary hypertension since 1980. Dr. Rich has conducted pioneering research on the molecular mechanisms, epidemiology, clinical presentation, natural history and treatments of the disease. This knowledge has lead to the discovery of more effective treatments for pulmonary hyperte...

Matthew J O'Brien

Associate Professor of Medicine (General Internal Medicine and Geriatrics) and Preventive Medicine (Epidemiology)

My work aims to eliminate health disparities in U.S. Latinos by examining the underlying causes and developing interventions to address them. Since 2007, my colleagues and I have focused on community health workers as a culturally-competent workforce to promote health and prevent disease in this population. Partnered closely with community-based organizations, we have developed and tested community health worker programs to prevent cancer, cardiovascular disease, and most recently diabetes. We conduct qualitative and epidemiologic studies to identify intervention targets in Latinos and develop...

Ankit Bharat

Associate Professor of Surgery (Thoracic Surgery) and Medicine (Pulmonary and Critical Care)

Dr Bharat is board certified in general surgery and thoracic surgery. His clinical interests include malignant and benign chest and esophageal diseases. Dr Bharat's research is focused on lung preservation, transplant immunology and airway biology, achieved through collaboration with the Kovler Comprehensive Transplant Center and the Division of Pulmonary and Critical Care Medicine.
