Paul T Schumacker, PhD

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

Our lab is interested in the effects of oxygen on cell metabolism, and in the molecular mechanisms underlying cellular oxygen sensing. The signaling pathways activated by hypoxia, and their regulation of transcriptional and post-translational responses in diverse cell types are also of major interest. Current studies focus on the role of mitochondrial redox signaling in the development of pulmonary hypertension. Other current studies focus on cardiomyocyte regeneration in the heart and molecular factors that regulate hypertrophic and hyperplastic remodeling responses.

Lisa D Wilsbacher, MD, PhD

Assistant Professor of Medicine (Cardiology) and Pharmacology

Dr. Wilsbacher's research focuses on cardiac development and cardiomyocyte maintenance in the setting of pathological stress. Currently, the laboratory investigates the G protein-coupled receptor sphingosine-1-phosphate receptor 1 (S1Pr1) and its unexpected role in cardiomyocyte proliferation and cardiac development. Her research aims to identify the signaling mechanisms that underlie these cardiac developmental effects and to investigate whether S1Pr1 signaling contributes to cardiac remodeling in the adult heart.

Tamara Isakova, MD, MMSc

Associate Professor of Medicine (Nephrology and Hypertension)

Dr. Isakova is a clinical nephrologist with experience in patient-oriented and epidemiological research of disordered mineral metabolism in chronic kidney disease. Dr. Isakova provides clinical care for patients with chronic kidney disease and bone and mineral metabolism disorders and for patients with kidney stones.

Rachel O'Conor, PhD

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

I am a health services and public health researcher. My research focuses on understanding cognitive and psychosocial determinants of chronic disease self-management behaviors and health outcomes. I am interested in the design and evaluation of pragmatic, health system and community-based self-management support interventions for chronically ill adults who experience significant social and economic hardship. Additionally, my research seeks to understand and address self-care complexity for individuals with multiple chronic conditions and bridge the gap between complex medical systems and indivi...

Thomas J Schnitzer, MD, PhD

Professor of Physical Medicine and Rehabilitation, Anesthesiology and Medicine (Rheumatology)

Research activities of our group focus on two major clinical areas: musculoskeletal pain and bone. In collaboration with Dr. A. Vania Apkarian in the Department of Physiology, our pain research focuses on understanding the basis for pain chronification, utilizing brain imaging and psychophysical methodologies. Current NIH-funded studies are evaluating the transition that occurs in individuals who progress from acute to chronic pain and attempting to modulate this by pharmacologic interventions. On a more applied level, the development and characterization of analgesic agents for the management...

Oluwadamilola A Adeyemi, MBBS

Clinical Assistant Professor of Medicine (Infectious Diseases)

Global Health/International Health, Tropical Medicine, Bacterial Infections, Parasitic Infections, Viral Infections, Diabetic Foot Infections, Osteomyelitis, Sexually Transmitted Diseases, Tuberculosis, Travel Medicine

Matthew J O'Brien, MD

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

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...
