Research Diets, Inc. is owned and managed by Edward A. Ulman, Ph.D., who has worked exclusively in lab animal nutrition for over 35 years. Dr. Ulman is the founder and chief executive officer of Research Diets, Inc. In addition, he is the inventor and driving force behind the BioDAQ product development.

It all started in 1984 in Ed Ulman’s kitchen where he made his first diet for lab animal research. Ed had spent many years in the research community and saw a need for a reliable source for custom purified diets. With his contacts in the industry and first hand knowledge of lab animal research he has built Research Diets into the largest purified diet company in the world.

Today the company has over 60 employees and has assembled a Resource Center staffed with nutritionists and food scientists providing expert consultation services to researchers worldwide. Research Diets specializes in manufacturing custom purified diets for diet induced disease models. One such model is in the study of obesity and diabetes where the company developed the “Original” high-fat diet for lab animal research. Over the years more than 30,000 custom formulations have been created for various areas of study.

The combination and synergy of OpenSource Diets and the BioDAQ food and liquid intake monitor, has placed Research Diets, Inc. on the forefront of the study of dietary effects on phenotype expression. 

The Research Diets, Inc. campus is located in New Brunswick, NJ USA consisting of three (3) adjacent buildings. OpenSource Diets production and scientific support teams occupy the first two and the BioDAQ production, R&D and technical support teams occupy the third.
