Current Postdoctoral Fellows

Michele Patel

Michele (“Shelley”) L. Patel, PhD is a postdoctoral research fellow at the Stanford Prevention Research Center. She completed her PhD in clinical psychology at Duke University and her clinical internship at the VA Palo Alto Health Care System, specializing in behavioral medicine. Dr. Patel’s research focuses on utilizing digital health tools to optimize behavioral interventions for obesity. Dr. Patel also studies the impact of intervention engagement and psychosocial factors (e.g., health literacy, stress) on treatment success. She enjoys playing and watching basketball and soccer.

Janneke van 't Hooft

Janneke van 't Hooft completed her PhD in medicine at Academic Medical Center (AMC) in Amsterdam, the Netherlands. Her PhD focused on improving evaluation research in obstetrics.  Alongside her research she is also a clinician and working at the department of Obstetrics and Gynaecology at the AMC. As a medical doctor she is confronted daily with the burden of preterm birth, which is the single most important cause of perinatal mortality and morbidity. While the volume published research on preterm birth is increasing, effective interventions for women (and their offspring) to actually prevent preterm birth are still lacking, preterm birth rates are rising and potentially effective interventions remain largely unevaluated. At METRICS she is therefore working as a postdoc on identifying research waste in preterm birth prevention to increase the effectiveness and value of research investments in this area.

Sparkle Springfield

Sparkle's research focuses on gaining a more in-depth understanding of the factors that contribute to poor dietary and physical activity outcomes in African American women. She is currently working on projects that include studies to understand individual and community level predictors of resilience and examine its relationship with CVD-related health behaviors, including diet quality. Her previous research examined socio-demographic and psychosocial predictors of dietary quality in African American breast cancer survivors enrolled in a community-based randomized weight loss intervention trial.

Valentin Danchev

Valentin Danchev, PhD, is a postdoctoral fellow at the Meta-Research Innovation Center at Stanford (METRICS) and at Stanford Prevention Research Center. Prior to joining Stanford, he was a postdoctoral scholar at the Department of Sociology, University of Chicago. Valentin received his doctoral degree in Development Studies from the University of Oxford, where he was also affiliated with the networks research group at the Mathematical Institute.
His current work is focused on meta-research, reproducibility, reward system and incentives in science, open data, and science policy, particularly in the domain of medical sciences. In his research, he uses large-scale data and computational approaches at the intersection of social network analysis, causal inference, and data science. He is a husband and a father of two boys, and his family enjoys going on hikes, biking, and music.

Kathleen Gali

Kathleen Gali, PhD is a postdoctoral research fellow at the Stanford Prevention Research Center. She received her PhD in public health from the University of California, Merced. Dr. Gali is interested in how social contexts, emotions, and policies influence health decision-making and behavior. She is also interested in the psychosocial impact on health outcomes, particularly in underserved communities. In her free time, she enjoys traveling, cooking, and spending time with family.

Priya Fielding-Singh

Priya Fielding-Singh is a Sociologist and Postdoctoral Research Fellow in Cardiovascular Disease Prevention at the Stanford Prevention Research Center. Her primary research agenda investigates health disparities across class, race, and gender in the United States. Her work has been published in journals such as Social Science & Medicine, Sociological Science, and the Journal of Adolescent Health. She holds a Ph.D. in Sociology from Stanford University, a M.A. in Cultural Studies from the University of Bremen, and a B.S. in Education and Social Policy from Northwestern University.

Patricia Rodriguez Espinosa

Patricia Rodriguez Espinosa, PhD, a native of Habana, Cuba, earned her Ph.D. in Clinical Psychology in 2018 and a Master of Public Health (Health Policy concentration) in 2017, both from the University of New Mexico. She held both doctoral and dissertation fellowships from the Robert Wood Johnson Foundation and was also a recipient of the American Psychological Association Minority Fellowship. Her research concentrates on health equity issues (particularly among Latinos), cardiovascular disease prevention, racial residential segregation, well-being across cultures, and the science of Community-Based Participatory Research. She has expertise in both quantitative and qualitative research methods. On her free time, she enjoys hiking, riding her bike to work, cooking and reading.

Anthony Crimarco

Anthony Crimarco, Ph.D., is a Postdoctoral Fellow in Cardiovascular Disease Prevention at the Stanford Prevention Research Center. His primary research interests include the health benefits of plant-based diets, the impact of the built environment on diet and physical activity behaviors, and the use of mHealth and eHealth in lifestyle interventions.
Outside of research, Anthony enjoys going to the gym, surfing, and spending time with friends and loved ones.

Erin Vogel

Erin Vogel, PhD, is a social psychologist and postdoctoral fellow at the Stanford Prevention Research Center. Funded by a fellowship award from the California Tobacco Related Disease Research Program, Dr. Vogel studies social influences on health behaviors and the use of digital tools, such as social media, to improve health. Her current research projects focus on teenagers' e-cigarette use, smoking in the LGBTQ+ community, and co-occurring health risk behaviors. Outside of research, her interests include cooking, working out, reading, and exploring the beautiful Bay Area.

Andrea Mendoza-Vasconez

Andrea S. Mendoza-Vasconez' PhD research has primarily focused on the promotion and maintenance of physical activity among Latino populations, using both quantitative and qualitative research methods. Dr. Mendoza-Vasconez is interested in citizen science as a means of empowering and mobilizing underserved communities, and in the use of technology to tailor interventions in a behavioral precision medicine approach.
Outside of research, Dr. Mendoza-Vasconez loves spending time with her family (especially her baby daughter Olivia), biking, learning new and challenging things (like surfing!), and traveling to new places (which will unfortunately be done sparingly in the future in an effort to reduce her ecological footprint).
