Research Interests: Treatment options for type 1 diabetes with a focus on automated insulin delivery systems.

Research Description: Dr. Brown’s clinical research is focused on new treatment options for type 1 diabetes. Dr. Brown is one of the original faculty members in the Center for Diabetes Technology and works in collaboration with engineers and mathematicians. She has been a principal investigator on multiple NIH-funded and FDA-regulated clinical trials focused on type 1 diabetes. These clinical research programs are aimed at further identifying factors of glycemic variability in people with type 1 diabetes, particularly glucose changes surrounding exercise, meals and the menstrual cycle. The Center for Diabetes Technology is active in developing automated insulin delivery systems in people with type 1 diabetes. Dr. Brown was the study chair for at least two major randomized-controlled multi-site US trials on automated insulin delivery that ultimately led to FDA approval of a system in current use in the US (Brown et al, NEJM 2019) and another under consideration by the FDA (Brown et al, Diabetes Care 2021).

Dr. Brown is a Principal Investigator for two NIH research grants: (1) R01 DK085623 (NIDDK; “Bio-behavioral Human Machine Co-Adaptation of the Artificial Pancreas”; July 2020-March 2025); and (2) R01 DK129553 (NIDDK; “Advanced Artificial Pancreas Systems to Enable Fully Automated Glycemic Control in Type 1 Diabetes Mellitus”; July 2021-June 2026). This work is aimed at developing fully automated insulin delivery systems that do not require carbohydrate counting as well as further understanding and optimizing the use of automated insulin delivery in improving the lives of people with Type 1 Diabetes.

Dr. Brown has previously been a principal investigator on an NIH K23 mentored clinical research award focusing on the effects of lactation on bone physiology.
