PhD Students, Candidates and Alumni

Michelle DeVost, MPH

Graduation Date: 2023

Education: California State University, Northridge (BS, Mathematics, Pure Mathematics and Classical Applied Mathematics concentrations); UCLA (MPH, Biostatistics)

Research Interest: My professional research experience ranges from statistical consulting for model development and biomarker validation in nursing to investigating sexual health behaviors and biomedical HIV prevention among sexual and gender minority communities. As a doctoral student, I am particularly interested in the principles of study design, statistical methods for clinical trials, applying mathematical modeling to public health research and leveraging electronic medical records data to investigate barriers to effective intervention implementation and to dynamically monitor and enhance population health.

Sepehr Hashemi

Graduation Date: 2023

Education: UC Davis (BS in Genetics with emphasis on genomics); Harvard School of Dental Medicine

Research interests: Predicting common surgical outcomes and complications, maxillofacial transplantation platforms, palliative therapy of oral cancer complications, and molecular assessment of treatment-specific complications in breast and prostate cancers

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.
