Virtual Graduation and Transitions

As we say goodbye to our graduating class and welcome our new fellows, we celebrate and make memories of these transitions. We will fondly look back and remember the time we shared growing together as physicians in this specialized field of medicine. 


Current Fellows

Chelsea Zimmerman, M.D.

Dr. Zimmerman is from Georgia originally and attended Auburn University for college and the Medical College of Georgia for medical school. She completed her pediatric residency training at the University of Florida and was thrilled to stay for fellowship as well. Dr. Zimmerman decided to become a pediatric endocrinologist when she was diagnosed with type 1 diabetes at the age of 16. Since then, it has been her passion to care for children with this disease. She volunteered at several diabetes camps and became involved in clinical research projects, including screening children with diabetes for retinopathy and in diabetes technology trials. Through her fellowship training, she has also developed an interest in Graves’ disease and improving current therapies.

Fellowship Research:
Prevalence and characterization of retinopathy in children with type I diabetes using a non-mydriatic fundus camera
Prevalence and characterization of retinopathy in children with type II diabetes using a non-mydriatic fundus camera

Brittany Bruggeman, M.D.

Dr. Bruggeman is a native Floridian who grew up on the Space Coast. She is proud to be a quadruple Gator, having completed undergraduate, medical school, residency and now fellowship training at UF — go Gators! In her spare time, she enjoys taking her dogs to the farmers’ markets, going to concerts and plays with her husband, reading novels and spending time at Disney with her family. Her interest in endocrinology started at the Florida Diabetes Camp, where she has been a volunteer for seven years. Patient advocacy, both on the community and legislative level, is her focus and passion throughout training. Dr. Bruggeman is an active leader in the AAP Section on Pediatric Trainees, on the ADA’s Legislative and Regulatory Subcommittee, and she authored a top 10 AAP resolution entitled “Affordable Insulin Access for all Children With Diabetes.” Dr. Bruggeman has participated in meaningful diabetes research since 2011, and projects have ranged from translational research in developing a bioartificial pancreas in a mouse model to clinical research in determining the prevalence of retinopathy in children with type I diabetes. She plans to continue as a clinician-scientist as well as an advocate for kids with T1D in her career.

Fellowship Research Projects:
– “Promoting health equity for youth with type 1 diabetes through outreach, networks, and education: All for ONE!”
– “Prevalence and Characterization of Retinopathy in Children With Type 1 Diabetes Using a Non-Mydriatic Fundus Camera”
– “Fundal Photography as a Screening Tool for Diabetic Retinopathy in Pediatric Type 2 Diabetes”
– “Effect of Substance Use on Type 1 Diabetes Pancreas Histopathology”

Tim Foster, M.D.

Dr. Foster grew up in South Florida, where he also attended medical school at Florida Atlantic University Charles E Schmidt College of Medicine. He attended the University of Florida for college and was excited to return to the swamp for residency and now fellowship. His interest in endocrinology started in medical school and his mentors at Joe DiMaggio Children’s hospital introduced him to Florida Diabetes Camp, where he’s volunteered for the past 5 years. His research interests include prevention and treatment of type 1 and type 2 diabetes and bone health.
