He additionally enjoyed learning more about longitudinal care for patients with HIV in his HIV continuity clinic. His interest in endocrinology starting with his research in medical school focused on the analysis of the Raman spectra of urine in patients with diabetes and other renal diseases and strengthened in residency via QI projects focused on improving diabetes care for his primary care patients.

Research Interests: Quality improvement, diabetes, obesity medicine
Sara grew up in the suburbs of Cleveland, Ohio. She moved to Boston where she completed Boston University’s coordinated master’s program in dietetics and nutrition, which included a year-long dietetic internship at Boston Medical Center. During her dietetic internship, she also developed a passion for medicine and its relationship with nutrition. She was particularly interested in obesity medicine and spent a majority of her elective rotations working at various bariatric surgery centers (including Brigham and Women’s Hospital and Boston Medical Center). She became a registered dietitian following completion of the program and started medical school shortly afterwards. During residency, Sara developed an interest in quality improvement and diabetes. Her interest in obesity medicine also continued. She co-authored a comprehensive textbook chapter about obesity management with a focus on nutrition for use in medical school curricula. She also developed a quality improvement initiative to increase documentation--and by extension, management-- of obesity in the ambulatory setting, which she presented at the Architecture of High Value Health Care national conference hosted by Johns Hopkins. After endocrinology fellowship, Sara hopes to pursue a career in clinical medicine with a potential focus on diabetes and obesity. In her free time, she enjoys martial arts, learning new languages, traveling, and spending time with her family and friends.

Vidhu Vadini
Hometown: Solan, India
Medical School: All India Institute of Medical Sciences
Residency: University of Arkansas for Medical Sciences
Clinical Interests: Obesity, Type 2 diabetes, monogenic diabetes, general endocrinology
Research Interests: Diabetes technology, metabolic syndrome and osteoporosis, endocrinopathies associated with immune checkpoint inhibitors
Vidhu was born and brought up in the hilly state of Himachal Pradesh in northern India. She moved to New Delhi for medical school and graduated from All India Institute of Medical Sciences. As an undergrad, she worked on qualitative research to assess beliefs and practices towards mental health illnesses and developed an interest in public health research. After graduating, she returned to her home state and participated in public health studies aimed at enhancing detection of tuberculosis cases in nearby villages by involving local governing figures who had a closer relationship with the community than health care professionals. She moved to the United States for residency and joined University of Arkansas of Medical Sciences in Little Rock. After her first endocrine rotation, she was determined to be an endocrinologist. She worked on osteoporosis research during her residency with Dr Ambrogini, to improve bone clinic referrals and subsequent osteoporosis therapy for patients admitted with hip fractures. This project won her the best QI project at the program's annual research symposium. In her final year of residency, she pursued thyroidology and collaborated with Dr Maraka to write a literature review on management of thyroid storm in pregnancy. She won the ACP- Arkansas chapter's best oral case presentation for thyrotoxicosis mediated cardiogenic shock. This was also presented at Endocrine Society 2023 meeting. Vidhu plans to pursue a career in academic endocrinology after her fellowship. In her free time, Vidhu can be found developing recipes and photographing her food, attempting and failing at gardening and giving fashion and interior design advice to anyone who asks. She can hike if requested.
