Fellows at the Division of Pediatric Endocrinology, School of Medicine at UNC Chapel Hill

Pediatric Endocrinology Fellows

Mark Henin, MDMark Henin, M.D.

3nd year fellow

I was born in New Orleans, aka “NOLA”. I only lived there for a short while before moving to Richmond, VA, where I spent the majority of my formative years. I attended VCU for both undergrad and medical school (Go Rams!). Match Day, I excitedly learned I would be packing my bags for the Tarheel State to pursue Pediatrics residency at Levine Children’s Hospital in Charlotte. My love of endocrinology and all things North Carolina (BBQ, Beaches, Blue Ridge Mountains, Basketball, Breweries) blossomed during residency so I was thrilled to learn I would be extending my stay and attending UNC for Pediatric Endocrinology fellowship. Since starting at UNC for my Pediatric Endocrinology fellowship, I have relished the opportunity to work with fantastic attendings who come from a variety of research backgrounds and who all place education as a top priority. I quickly discovered that there is no shortage of pathology at UNC. In my short time here I have been personally involved in the diagnosis and management of patients with new onset diabetes, panhypopituatirism, adrenoleukodystrophy, Turner Syndrome, 46 XY ovotesticular DSD, Graves’ disease, congenital hypothyroidism, PCOS, MEN (1a and 2a) and thyroid carcinoma (papillary and follicular) both on the inpatient wards and in the clinic. As a top flight academic institution located in the heart of the Research Triangle, UNC also provides a plethora of clinical, translational or laboratory research opportunities for fellows. I am currently participating in bench research exploring the development of a non-depleting, bispecific anti CD4/CD8 antibody in a humanized, non-obese diabetic (NOD) mouse model to inhibit T-cell mediated islet cell destruction. Previous studies using separate, individual CD4 and CD8 antibodies have shown rapid and sustained remission of diabetes in newly diagnosed NOD mice. If the bispecific antibody study proves successful, the goal is to bring it to clinical trial to potentially reverse the course of islet cell destruction in patients with newly diagnosed Type I diabetes.

2nd year fellow

I am a Michigan girl, born and raised. I attended the University of Michigan for undergraduate training, and then headed to Chicago for medical school at Northwestern University. Residency training brought me to UNC, and after spending an elective rotation with the Pediatric Endocrinology department my intern year, my passion for pediatric endocrinology was solidified. As a resident, I was fortunate enough to find multiple mentors in the endocrinology department, who encouraged me to seek out multiple academic projects – including a podium presentation at the Southern Pediatric Endocrine Society meeting. Since joining the division as a fellow, I have had the opportunity to learn from this exceptional group of scientists and clinicians, who push me to think critically and learn from my patients. Our faculty have continually supported and encouraged me to pursue my personal interests – specifically quality improvement, education, and the care of children with gender dysphoria – which has made my time here fun and rewwarding. In my time off, I love to spend time outside with my husband – whether it is snowboarding in the mountains, or relaxing on the beach. But if it is a Saturday in the fall, you can find me cheering on my Michigan Wolverines!

Rhonda Winchester, MDRhonda Winchester, M.D.
1st year fellow

Originally from South Carolina, I have always been a southern girl. My experiences with my sister having type-one diabetes strongly influenced me at a young age in my career path. Although there are no doctors in my family, I sought to take on this calling. I attended undergrad at a small all-female college, Columbia College, in South Carolina, were I majored in Biology and Chemistry. Thereafter, I completed medical school at the Medical University of South Carolina. All the while, I participated in various experiences that strengthened and enriched my love for taking care of those with diabetes and other endocrine disorders. I completed my residency in pediatrics at The Children’s Hospital of the King’s Daughters through the Eastern Virginia Medical School in Norfolk, Virginia. I am blessed to now be at the University of North Carolina to complete my training and become a pediatric endocrinologist. My research interests include the autoimmune process as it relates to the development of type-one diabetes. In my first year of fellowship, thus far, I have already taken care of and diagnosed patients with conditions such as new-onset Addison’s disease, congenital hypoparathyroidism, hyperinsulinism, type-one and type-two diabetes, and hypo- and hyperthyroidism. I have found strong support from the staff in my education and growth as a pediatric endocrinologist in-training. I am continuously learning and enhancing my clinical knowledge with each patient encounter. In my spare time, I love to spoil my dog, Kolby; run; garden; and spend time with my family.
