Endocrinology & Metabolism Newsletter

October 2023

Dear Colleagues,

As the new university semester begins, the air is a bit crisper, reminding us of the impending change in seasons. Likewise, it is a season of change in the academic year as well. We welcomed two outstanding new clinical fellows in July, and we welcome three new faculty as well. We are in the midst of recruiting next year’s fellows, and we continue to search for new clinicians and researchers to fulfill our strategic vision for an expanded Section of Endocrinology and Metabolism.

Of course, it is also a time for leaving, and we take notice of Dr. Karl Insogna’s partial retirement in a story featured in this newsletter. Although Dr. Insogna officially hung up his stethoscope on July 1, 2023, his R01 was renewed for another five years. Therefore, he will continue to have a positive impact on patients through his research. Luckily for us, we will still be able to find him in the lab. We also say goodbye to Dr. Renata Belfort De Aguiar, who is leaving to take an exciting new job as clinical research director of the Texas Diabetes Institute at the University of Texas at San Antonio. As with Dr. Insogna, Dr. Belfort De Aguiar will continue to interact with her Yale colleagues on ongoing research studies. It is hard to leave Yale entirely!

As always, our faculty are working hard seeing patients, teaching students, clinical fellows, and postdoctoral fellows, and pushing the boundaries of medical knowledge. I am immensely proud of all their great work, and I hope that you enjoy reading the stories below, which highlight a few of the many ways our section is at the forefront of scientific discovery and patient care.
