Wendy Bevier, Ph.D.

Wendy Bevier, Ph.D., is an Associate Investigator with the Institute and is coordinating the National Institutes of Health (NIH) studies. She is responsible for recruiting patients, conducting experiments, and collecting and organizing data. A procedure called the hyperinsulinemic euglycemic clamp and continuous glucose monitoring systems are being used during this project.
