Our Team

Principal Investigator

Tashara M. Leak, Ph.D., R.D.

Dr. Leak is the Lois and Mel Tukman Assistant Professor in the Division of Nutritional Sciences at Cornell University. As a health disparities researcher, she conducts interventions that address socioeconomic and environmental influences on food choices, while drawing upon her expertise in mixed methods and community-based research. More specifically, Dr. Leak designs innovative and culturally relevant interventions that aim to improve dietary behaviors among minority adolescents that reside in urban, low-income communities. She is deeply committed to conducting research that informs public health programming and policy.




Post-Doctoral Students

Alexandra (Lexi) MacMillan Uribe, Ph.D., R.D.

Lexi is a postdoctoral fellow for the NIH-funded Institutional Training Grant in Maternal and Child Nutrition. Her PhD dissertation (University of Wisconsin-Madison, 2018) focused on delivering nutrition education to the mother-infant dyad within a primary-care group approach. Lexi’s long-term research goal is to find effective community-focused strategies that address health equity by helping mothers and children establish healthy dietary patterns. Specifically, she would like to use dissemination and implementation models and information and communication technologies to enhance the effectiveness of nutrition education interventions and inform public health policy. When not engaged in research and service, Lexi enjoys exercising, cooking Peruvian dishes passed down from her mother and grandmother, and spending time with her family and Duck-Tolling Retriever mix, Ginger.

Deena B. Thomas, Ph.D., M.S.

Deena is the public health Teaching and Research Fellow for the Division of Nutritional Sciences (DNS). In this capacity, she supports instruction for courses in introductory public health, public health nutrition and a course for students who have completed their public health practicums. Deena was drawn to the research in DNS because she is interested in how nutrition education interventions can mitigate the health impact of toxicants in communities that are
most disproportionately affected by environmental exposures such as lead. Deena comes to Cornell with a PhD in Environmental Health Sciences and a Masters in Epidemiology from the University of Michigan School of Public Health. After completing her doctoral work on the cognitive effects of environmental fluoride during childhood, she worked with researchers from the Institute for Social Research at the University of Michigan on how family structures and
other social factors impact health, particularly in the elderly. When Deena is not teaching or conducting research, she likes to hike and bike through Ithaca’s natural areas with her family.


Doctoral Students

Navika Gangrade, R.D.

Navika is a combined Ph.D./R.D. student and predoctoral fellow for the NIH-funded Institutional Training Grant (T32) in Maternal and Child Nutrition.

She completed her dietetic internship at Cornell University/University of Rochester Medical Center and became a Registered Dietitian in 2019. In her current position, she will implement a culturally appropriate, snacking-based intervention for diverse adolescents from a low-income, urban community, in an overall aim to remediate diet-related health disparities and promote health equity. Navika hopes to stay on the academic track and form a career as a health equity-focused research faculty member. Outside of work, she enjoys yoga and indulging in the local food scene.



Felicia J. Setiono, MSPH

Felicia Setiono is originally from Indonesia. She earned an MSPH in Human Nutrition from Johns Hopkins Bloomberg School of Public Health and a BS in Biological Sciences from Cornell University. Through her studies and research, Felicia has developed an interest in understanding how environmental and social factors impact dietary behaviors, especially in low-income communities. At her current position, she hopes to serve and build local capacity to improve the nutritional status and well-being of underserved communities. Felicia is also interested in the role of nutrition education and participatory research in shaping health policies at both the local and national levels. In her free time, Felicia enjoys cooking, baking, and sharing the end products with those around her.
