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.
