She obtained a Bachelor of Science degree in Mathematics from Spelman College in Atlanta in 2003. Dr. Chatman is interested in using her statistical and quantitative skills to conduct health disparities research that can be translated into better intervention strategies within minority communities. Her previous research experiences have included working in areas of health disparities research related to infants and adolescents. She collaborated and published research on racial and gender difference in access to substance abuse services among Medicaid adolescents. She also led a meta-analysis research project on racial disparities and infant mortality, related to the Hispanic Paradox. Dr. Chatman is at the University of Pittsburgh site where she will work on her current research focus of addressing physical and emotional health risks of minority single mothers during middle age.



Karen Ertel, ScD
Dr. Karen Ertel completed her Doctorate of Science (ScD) at Harvard School of Public Health in June 2008, where she studied social epidemiology, maternal and child health, and methods of biostatistics and epidemiology. Karen also holds a MPH in Maternal and Child Health from the University of California, Berkeley and a BS in Biopsychology from Georgetown University. Karen's research interests include maternal mental health, child health and development, and work-related factors that impact health. Her dissertation research focused on maternal depression and its impact on child physical size and growth during infancy and early childhood. She hopes to extend this research to study social and psychosocial determinants of maternal mental health and explore social factors that contribute to racial/ethnic disparities in maternal mental health and how these may translate into poor health in the next generation. Karen's interests also include developmental origins of disease and lifecourse theory and methods. She plans to explore how we can use these frameworks to better understand racial/ethnic disparities across the lifecourse. Karen is at the Harvard School of Public Health.



Patricia Miranda, PhD
Dr. Patricia Y. Miranda is a Kellogg Health Scholar Postdoctoral Fellow at the University of Texas M. D. Anderson Cancer Center, Center for Research on Minority Health. She completed her PhD in Health Behavior and Health Education at the University of Michigan School of Public Health in 2008, where she also received her MPH in 2003. She received her BA in Sociology at Trinity University in San Antonio, TX in 2001. Dr. Miranda’s research interests focus on the relationship between place and health disparities, specifically among Latino populations. Research topics include social determinants of health disparities, mental and physical comorbidities, Latino health, understanding the contribution of sociopolitical context to within-group differences among Latino populations, and using a community-based participatory research approach to population health to create multilevel national, regional and local Latino health agendas and policy. Her research experience also includes a CBPR approach to examining social and physical determinants of risk factors for cardiovascular disease in a multiethnic population, and systematic direct observation of the built environment and pedestrian physical activity along urban greenways.

Anthony Omojasola, DrPH
Dr. Anthony Omojasola, research interests are in reducing health service disparities in low-income populations, especially as they relate to health care access, health insurance, and prescription drugs. During his W.K. Kellogg Health Scholars Program fellowship at the University of Texas MD Anderson Cancer Center, Center for Research on Minority Health, he will be examining the utilization of discount generic prescriptions as a way of reducing health disparities among low-income populations. Additionally, he will be examining the capacity of public and primary care providers that serve the uninsured, underinsured, and Medicaid populations in Houston. The demand for primary care by the uninsured will be compared to supply to monitor service gaps and evaluate initiatives to expand capacity. His educational background includes: B.S. Health Care Administration and Planning (Tennessee State University, Nashville), Master of Health Administration (Tulane University, New Orleans), and Doctor of Public Health (University of Kentucky, Lexington). He is a Fellow of the American College of Healthcare Executives. More Information



Lisa Rosas, PhD
Dr. Lisa Goldman Rosas received her PhD in Epidemiology from the University of California, Berkeley School of Public Health in 2008, where she also received her MPH in Maternal and Child Health. Her work experience includes conducting case management and health education with migrant farmworkers and their families, coordinating a rural migrant health program, and working in Mexico as a research fellow with the Population Council. Most recently, Dr. Rosas served as the community outreach and translational research coordinator for the Center for Children's Environmental Health Research (CCEHR) at UC Berkeley. Her dissertation research examined the disparity in childhood obesity among children of Mexican descent by taking a binational (US-Mexico) approach. Dr. Rosas continues to investigate the disproportionate prevalence of overweight among children of Mexican descent by critically examining the acculturation hypothesis and investigating other promising avenues. Her research falls into four areas: (1) understanding the complex interactions between migration, acculturation and socioeconomic status and their influence on childhood obesity; (2) investigating modifiable early-life risk factors for overweight among children of Mexican descent; (3) identifying policies that are effective in curbing the childhood obesity epidemic among Mexican Americans; and (4) examining factors related to childhood overweight in Mexico. Immigrant health research rarely takes such a binational approach; however, taking into account the context in the country of origin is crucial for fully understanding the determinants of health outcomes in immigrant populations in the US. Dr. Rosas is at the University of California, San Francisco site. More Information



Emma Sanchez-Vaznaugh, ScD
Dr. Emma Sanchez-Vaznaugh, completed a doctorate in Social Epidemiology at Harvard University's School of Public Health, Department of Society, Human Development and Health. Dr. Sanchez is a W.K. Kellogg fellow alumna in Health Policy Research and a KHS in the multidisciplinary track at the University of California, San Francisco site. She is also an assistant professor at San Francisco State University, Department of Health Education, where she teaches courses in epidemiology and biostatistics. Her research examines the social, policy and environmental determinants of health. This work requires particular attention to the influence of places (i.e. birthplace, place of residence, schools), socioeconomic position and immigrant status on social disparities in health. Dr. Sanchez's research involves multilevel studies on the influence of physical and social environments on health as well as individual level studies on social disparities in health. Dr. Sanchez is interested in how social and environmental factors shape health, risk factors and behaviors with emphasis on cardiovascular disease risk factors over the life course. Her research examines: 1) how neighborhood conditions (social and physical) and their interaction with individual factors may influence health, disease and behaviors; 2) the impact of school nutrition and physical education policies on body weight and health behaviors; 3) the shape, direction and magnitude of the socioeconomic gradients in health and disease among diverse social groups defined by gender, race/ethnicity and immigrant status; and 4) the impact of migration on health and disease outcomes.

Besangie Sellars, PhD
Dr. Besangie Sellars received her undergraduate degree in psychology from Hampton University in 2003. She completed her PhD in developmental psychology at the University of Michigan, with an emphasis on lifespan and late life development. Currently, Besangie is at the University of Pittsburgh site. During her doctoral studies, Besangie's research focused on the well-being of older minority populations, and the positive role of social relations. She has been involved in research investigating racial and ethnic differences in caregiving preferences, as well as the role of social support in the link between socioeconomic status and health. Her dissertation investigated demographic differences in sex role endorsements, as well as how social relations may impact sex role endorsements across the lifespan. Besangie's general research interests include the factors that promote healthy lifespan development among minority populations. Specifically, she is interested in how social relations can both increase/improve longevity as well as reduce health disparities. More Information



Kellee White, PhD
Dr. Kellee White completed her PhD in Epidemiology from Columbia University's Mailman School of Public Health in 2008. She holds a BA in Sociology from Vassar College and a MPH in Sociomedical Sciences from Columbia University. Her dissertation examined the relationship between racial/ethnic residential segregation and hypertension as well as investigated the intervening mechanisms between residential segregation and hypertension. Her research interests include: 1) the methodological and conceptual issues related to the study of racial/ethnic residential segregation and health outcomes; 2) the contribution of racial/ethnic residential segregation to health disparities; 3) the accumulation of disadvantage across the lifecourse and its influence on chronic disease in old age; and 4) the intersection of epidemiology, urban planning, social and public policies to address health disparities and improve population health.
