David M Shapiro, MD

Assistant Professor of Medicine (Gastroenterology and Hepatology)

I perform primary and secondary endoscopic (non-surgical) therapies for obesity, including placement of the Orbera gastric balloon, the Aspire Assist device and endoscopic sleeve gastroplasty. I also perform gastro-jejunal outlet reduction for weight regain after bariatric surgery. I have also been trained to use the EsophyX device (TIF procedure) as a minimally invasive (non-surgical) treatment for GERD. I am also interested in endoscopic treatment of post-surgical complications and endoscopic suturing.

Robert P Schleimer, PhD

Professor of Medicine (Allergy and Immunology), Microbiology-Immunology and Otolaryngology - Head and Neck Surgery

I am interested in the mechanisms of pathogenesis and treatment of a variety of allergic and inflammatory diseases associated with allergy. These include chronic rhinosinusitis, asthma, hay fever, rhinitis, food allergy and others. We also study the mechanisms of action of antiinflammatory glucocorticoids. Our studies focus on the molecular and cellular mechanisms underlying disease and steroid action as well as developing strategies to for new treatments.

Jody D Ciolino, PhD

Assistant Professor of Preventive Medicine (Biostatistics) and Medicine (General Internal Medicine and Geriatrics)

I am a clinical trialist / study design specialist; my research interests include clinical study design and conduct, database development and data (quality) monitoring, interim monitoring / reporting / analyses, randomization and treatment allocation techniques (including cluster-randomization allocation techniques), and clinical trial data analyses. My applied / collaborative research focuses on clinical studies applied to a wide range of disorders, diseases, and populations including those in the fields of perinatal depression, mood disorders, internal medicine and geriatrics, gastroenterolo...

David T Liss, PhD

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

My program of research seeks to test and evaluate new models of team-based, high-value primary care delivery.

HIV and organ transplantation, 2. HIV and HCV co-infection, 3. infectious diseases outcomes after organ transplantation, and 4. infectious diseases outcomes in mechanical circulatory support recipients.

Karen M Ridge, PhD

Professor of Medicine (Pulmonary and Critical Care) and Cell and Molecular Biology

My research interests focus on the intermediate filaments (IFs), which are cytoskeletal structures that are crucial for maintaining the structural integrity of cells and tissues. In general, my lab focuses on the non-mechanical roles for the IF cytoskeleton such as how IFs regulate cell migration and cell survival, and the mechanisms by which IFs are a scaffold for stress-activated kinases and adaptor proteins. We investigated whether micromechanical forces, such as shear stress and stretch, had an effect on the keratin intermediate filament (IF) network in alveolar epithelial cells. We demons...
