Dawn Hershman, MD, MS, Professor of Medicine and Epidemiology
Dr. Hershman has developed a nationally recognized expertise in the areas of breast cancer survivorship, late-effects of cancer therapy, health outcomes, health disparities research, and cancer clinical trials. She has conducted many successful and productive research projects in areas of high relevance for quality of cancer care. Dr. Hershman’s work has impacted improving quality of life, reducing cost, and improving outcomes for breast cancer survivors.

Grace Hillyer, Ed.D, MPH, Assistant Professor of Epidemiology
Dr. Hillyer is a cancer prevention researcher with expertise in community-based cancer screening. Her research focuses on the investigation of the multilevel determinants of health behaviors, particularly cancer screening/early detection behaviors among minority populations and increasing rates of positive health behaviors using tailored educational interventions.

Judith Jacobson, DrPH, MBA, Associate Professor of Epidemiology
Dr. Jacobson’s research focuses include disparities in cancer outcomes and barriers to timely diagnosis and treatment in cancer care.

Alfred Neugut, MD, PhD, Myron M. Studner Professor of Cancer Research and Professor of Medicine and Epidemiology
Dr. Neugut is a medical oncologist with a particular interest in gastrointestinal tract cancers, especially colorectal and gastric cancers. His research has centered on cancer epidemiology and prevention, with a major focus on the occurrence of second malignancies. Dr. Neugut spends a significant amount of time studying the quality of care in the use of chemotherapy and radiotherapy for cancers among different patient populations.

Prakash Satwani, MD Associate Professor of Pediatrics
Dr. Satwani's research focuses on clinical outcomes of children undergoing stem cell transplant for malignant and non-malignant diseases. Dr. Satwani's research also focuses on reducing clinical risk and examining healthcare utilization and the financial impact of stem cell transplant on families.

Wei-Yann Tsai, PhD, Professor of Biostatistics
Dr. Tsai’s research interests include analyses in survival, incomplete data, missing covariates and repeated measurements in cancer clinical trials and observational studies.

Jason Wright, MD, Sol Goldman Associate Professor of Obstetrics and Gynecology, Division of Gynecologic Oncology
Dr. Wright has extensive experience in health services and comparative effectiveness research. His prior work focuses on complications of cancer treatment, conservative oncologic surgery, disparities in access to care, and the quality of cancer treatment. His research interest includes exploring the quality of care for cancer patients who experience treatment-related complications.

Affiliated Faculty

Jeffrey Bruce, MD, Edgar M. Housepian Professor of Neurological Surgery Research
Dr. Bruce’s research interests include translational brain tumor research with an emphasis in glioma immunotherapy, progenitor cell biology, and drug delivery systems. Clinically, he specializes in surgical neuro-oncology, with particular interests in skull base, pineal tumors and pituitary tumors.

Benjamin Lebwohl, MD, MS, Assistant Professor of Medicine and Epidemiology
Dr. Lebwohl is a clinical gastroenterologist with a research focus on the epidemiology of celiac disease, with a specific focus on risk factors, quality, and outcomes. Dr. Lebwohl collaborates with institutions in the United States and abroad in epidemiology, patterns of care, and the natural history of celiac disease.

Ana Tergas, MD, MPH, Assistant Professor in the Division of Gynecologic Oncology
Dr. Tergas’ primary research interest is barriers to quality gynecologic cancer care among underserved and disadvantaged populations. Dr. Tergas is also interested in the correlation among race, treatments, and survival of ovarian cancer patients.

Mary Welch, MD, Assistant Professor of Neurology, Division of Neuro-Oncology
Dr. Welch has a long-standing interest in clinical research as a means to improve the lives of cancer patients and their caregivers. Her current research interests include improving patient access to investigational trials and sub-specialty services.


Instructors and Post-doctoral Fellows

Siyang Leng, MD, Instructor in Medicine, Division of Hematology Oncology
Dr. Leng research interest focuses on studying patterns of care in multiple myeloma and amyloidosis, and the impact of various practices on patient outcomes.

Lenat Joffe, MD, Postdoctoral Research Fellow, Division of Pediatric Hematology Oncology
Dr. Joffe is a pediatric oncologist whose research interests include the impact of co-morbidities, such as obesity and poor nutrition, on toxicities and long-term survival in pediatric patients.

Justine Kahn, MD, Instructor, Postdoctoral Research Fellow, Division of Pediatric Hematology Oncology
Dr. Kahn is a pediatric oncologist whose research interests are in cancer care delivery, health disparities, and survival outcomes among children and adolescents with hematologic malignancies, specifically Hodgkin and non-Hodgkin lymphoma and acute lymphoblastic leukemia.
