We know our products will be evaluated every day with thousands of animals so the research has to be done correctly

Completing his 33rd year conducting research at the Purina Animal Nutrition Center, Dr. Miller has led the animal milk research effort for the last 30 years. During his tenure, he has also led research efforts in beef, swine, dairy and companion animals and basic proteins.

“The process of generating other approaches for new products is particularly enjoyable to me,” says Dr. Miller. “You need to understand the market. Then you can begin to dream of other ways to satisfy a need. Many ideas won’t be considered for long, but a few will be. These ideas or concepts are then scrutinized, usually through animal studies, and only a few will ever find their way into viable products.”

Dr. Miller’s research areas of expertise and interests include:

  • Young animal nutrition and health
  • Protein and carbohydrate nutrition
  • Feed intake and acceptance
  • Comparative nutrition 

Throughout my career with this company, I have examined ways of improving the nutrition and well-being of young and infant animals,” says Dr. Miller. “I am particularly proud of the nutritional approaches and understanding developed during the last 30 plus years for these high need babies.”  

Dr. Miller grew up on a farm and had several pets including piglets, roosters, raccoons and even a muskrat. “At a young age I learned how to work with, approach and appreciate animals,” says Dr. Miller. “I learned that the quick way wasn’t the best way and, many times, not the fastest way. I’ve enjoyed sharing this with my children and others.” 

Dr. Miller earned a bachelor’s and master’s degree from the University of Illinois and a Ph.D. from the University of Minnesota. He’s had roughly 30 patents issued.
