Daisy Duan

Daisy Duan (Year 3)

Hometown: New York, NY
Medical School: NYU School of Medicine

Clinical Interests: General endocrinology, pituitary diseases, obesity, diabetes
Research Interests: obesity, sleep/circadian rhythm basis of metabolism

Daisy grew up in New York City, where she attended medical school at NYU School of Medicine and completed her internal medicine residency at Icahn School of Medicine at Mount Sinai. She then worked as a hospitalist before starting her endocrinology fellowship. Since fellowship, Daisy has developed a research interest in the role of circadian rhythm on obesity and metabolism. Under the guidance of her mentors, she is investigating the effect of time-restricted feeding on weight loss and glucose homeostasis and conducting physiology-based studies on the effect of late dinner on glucose and fatty acid oxidation. Daisy plans to pursue a career as a clinician-scientist in obesity/metabolism with a focus on sleep/circadian rhythm.

Colleen Gavigan

Colleen Gavigan (Year 2)

Hometown: Scranton, PA
Medical School: University of Virginia School of Medicine
Residency: University of Pittsburgh PA

Clinical Interests: General endocrinology, diabetes, obesity
Research Interests: Medical therapies in diabetes and obesity

Colleen grew up outside of Scranton, Pennsylvania. She attended Bucknell University in Lewisburg, PA as an undergraduate and subsequently worked briefly in editing for a medical communications company in Manhattan, NY. She did a year of research at the Eunice Kennedy Shriver National Institute of Child Health and Human Development in pediatric endocrinology, specifically looking at the genetics of Kallmann syndrome. Afterwards she attended medical school at the University of Virginia, followed by internal medicine residency at the University of Pittsburgh Medical Center. She enjoys spending time outdoors, particularly with her coonhound, Maisie.

Hasan Husni

Hasan Husni (Year 2)

Hometown: Baghdad, Iraq
Medical School: Misr University for Science and Technology (Egypt)
Residency: John H. Stroger, Jr. Hospital of Cook County Chicago

Clinical Interests: General endocrinology, diabetes, disorders of bone and mineral metabolism.
Research Interests: Disorders of bone and mineral metabolism

Hasan was born and raised in Baghdad and from there, traveled to several other places to achieve his dream of becoming an endocrinologist. His passion for endocrinology started during medical school. He was intrigued by the feedback pathways of the different hormones and the concept of “inappropriately normal” lab tests. That passion continued to grow during his residency and fellowship. Hasan is interested in all the subspecialties of endocrinology and his goal is to become a well-rounded endocrinologist, with some focus on diabetes and bone health. Outside of medicine, Hasan likes to play tennis, read, and grow his recent hobby for astrophotography!

Jordan Perlman

Jordan Emily Perlman (Year 2)

Hometown: Washington, DC
Medical School: University of Vermont College of Medicine
Residency: University of Washington Seattle, WA

Clinical Interests: Pituitary disorders, type 1 diabetes mellitus, ICI-induced immune-related (endocrine) adverse events
Research Interests:  Mechanisms underlying development of ICI-induced autoimmune diabetes and other endocrinopathies

Jordan was born and raised in Washington, D.C and attended medical school at the University of Vermont in Burlington. She has been involved in Endocrinology research since before medical school through the National Institutes of Health IRTA program. She studied hemoglobin A1C discordance during residency and presented her work at several national meetings. Jordan is completing the Clinical and Basic Science Research Track and hopes to remain in academics as a clinician-scientist. Her research mentor is Dr. Jennifer Mammen and together they are trying to elucidate the mechanisms underlying ICI-induced autoimmune diabetes so that better screening protocols and potential therapies might be developed.
