The Jonathan E. Rhoads Lectures

The Rhoads Research Lecture is the highest and most prestigious of ASPEN's annual research honors. This tribute to Dr. Jonathan Rhoads recognizes his pivotal role in the field of specialized nutrition support. The lecturer is someone who is recognized internationally for major contributions to the field of nutrition and metabolic support, and who has demonstrated a career-long commitment to the improvement of the nutritional status of the patient.

Congratulations to the 2025 Jonathan E. Rhoads Lecturer!

Douglas G. Burrin, PhD, obtained degrees in animal science at Purdue University and the University of Nebraska. He completed a postdoctoral fellowship at the USDA Agricultural Research Service (ARS) Children’s Nutrition Research Center (CNRC) in Houston where he is currently appointed as a Research Physiologist with USDA-ARS and Professor of Pediatrics at Baylor College of Medicine (BCM).

Dr. Burrin is recognized for his knowledge and expertise in the fields of human nutrition, metabolism, and gastroenterology. Dr. Burrin has been a leader in the use of the pig as a translational animal model of human pediatric nutrition and gastroenterology. His research has highlighted the importance of enteral nutrition and the function of key gut hormones, such glucagon-like peptide 2 and fibroblast growth factor 19, in the pathogenesis of pediatric GI and liver disease. He has also made important contributions in understanding how parenteral nutrition and lipid emulsions impact intestinal adaptation and liver disease.

He has received national awards for his research, including the Mead Johnson Award from the American Society for Nutrition, the Growth and Development Award from the American Society for Animal Science, the ARS Senior Scientist of the Year, and the Bruce Bistrian Mentorship Award from ASPEN. His leadership in mentoring has been recognized by the Excellence in Research Mentorship Award from the Department of Pediatrics at BCM. He has mentored 60 postdoctoral fellows and graduate students resulting in 70 peer-reviewed articles.

He currently serves on the editorial board of the American Journal of Physiology-GI & Liver Section. Dr. Burrin is also a Director of the fellowship research training in the Division of Pediatric Gastroenterology, Hepatology, and Nutrition at Baylor College of Medicine. He also serves in the leadership of the NIDDK-funded Texas Medical Center Digestive Disease Center and as Director, Pilot and Feasibility Program. He has served on the ASPEN Task Force on Intravenous Lipid Emulsions and is a past member of the ASPEN Rhoads Research Foundation Grant Review Committee and Board Member.
