Deanna Hoelscher, PhD, RD, LD

Director, Michael & Susan Dell Center for Healthy Living

The University of Texas Health Science Center (UTHealth) School of Public Health in Austin

Dr. Hoelscher has always been interested in food, nutrition, science, and math. She started studying Chemical Engineering at Texas A&M, but after touring a chemical plant and visiting with a career counselor, she decided to study Food Science and Technology. While pursuing her Masters in Nutrition at UT Austin, she became a Registered Dietitian, refining the skills researchers need (detail-oriented, resourceful, self-motivated, hard worker); and enabling her to connect, interact, and communicate with people from diverse backgrounds. She had many leadership opportunities, including taking taking the lead on the Academy’s Position Paper on Child Overweight and Obesity. After earning her PhD in Biological Sciences she worked on CATCH, leading her to a tenure-track job at UTSPH. In 2006, when UTSPH received a grant from the Michael & Susan Dell Foundation, she moved to Austin and became the Center Director.

Currently, Dr. Hoelscher is working on many projects including: interventions, epidemiologic surveys, and policy – analysis. One of those projects is the Texas Childhood Obesity Research Demonstration (Texas CORD) project. She explains, “This is a multi-component project linking many of my previous studies into one intervention program. I am really excited about the links we are building between primary care physicians and community programs for families of diverse, low-income children who are overweight and suffer from child obesity. These families need resources and assistance, and we provide them through the Texas CORD project. I especially like reading our

success stories about families who have achieved better health through our program- that’s the true impact of public health and what I do.”
