Sarah Raifman

Sarah Raifman, MS

Graduation Date: 2023

Education: Brown University (AB, Development Studies), Harvard University (MS, Global Health and Population)

Research Interests: sexual and reproductive health, health policy and social epidemiology. I work at a UCSF research program called Advancing New Standards in Reproductive Health (ANSIRH), where I focus on evaluating the consequences of abortion restrictions on health and wellbeing, measuring the morbidity and mortality due to unintended pregnancy and unsafe abortion, and exploring new models for family planning and abortion service provision. I am interested in conducting innovative policy-relevant research to expand access to quality reproductive health services.

Marta San Luciano Palenzuela, PhD student at UCSF Department of Epidemiology and Biostatistics

Marta San Luciano Palenzuela, MD

Graduation Date: 2023

Education: University of Navarre, Spain (MD), Boston University (Residency, Neurology), Beth Israel Medical Center (Fellowship, Movement Disorders), Albert Einstein College of Medicine (MS Clinical Research Methods)

Research Interests: I am a clinical neurologist with specialty training in movement disorders, and my research interests are broadly in clinical and genetic epidemiology of Parkinson's disease, dystonia and other movement disorders and neurodegenerative illnesses, as well as in outcomes research in neurology and neuromodulation surgeries. My current research focuses on identifying predictors of favorable motor outcomes following deep brain stimulation surgery in isolated dystonia, a disabling movement disorder. While this type of surgery can improve symptoms in many patients, there is great variability in results and a great proportion of non-responders exist. Genetic etiologies of dystonia and different phenotypes may underline some of the differences. By means of the doctoral program, I hope to improve my understanding of research methodology to be able to identify such predictors in an innovative way and improve clinical care for this population.
