Research
Overview
My academic and scholarly interests focus on improving clinical outcomes and quality of life for patients with chronic diseases through the clinical practice guidelines development and the design, evaluation, and delivery of effective graduate medical curriculum.
I am nationally known for leading diabetes care and technology workshops and presentations for the last 5 years. In 2025, I coauthored a novel clinical practice guideline, entitled “Lifestyle Interventions for Treatment and Remission of Type 2 Diabetes and Prediabetes in Adults.” with a select group of multi-disciplinary experts. This landmark guideline offers clear, actionable, and evidence-based strategies for helping individuals with prediabetes or type 2 diabetes optimize their lifestyle behaviors, sustain positive changes, and potentially reduce or eliminate the need for medications.
I was also thrilled to have co-authored with first author and graduate PA student mentee, Jay Gandhi, a retrospective study on the use of telemedicine in diabetes care delivery published by the Journal of Diabetes Science and Technology. Finally, I had the privilege of collaborating with Dr. Anika Anam (PI) and Dr. Donna Windish, Program Director of the Yale GIM Medical Education Fellowship on a novel curricular initiative in the Yale PA Program. In late 2025, the study, "Implementing an Innovative Transgender and Gender Diverse Health Curriculum for Physician Assistant (PA) Students" was published in AACE Endocrinology and Diabetes.
Additionally, I worked with a select group of providers to develop two YNHHS Care Pathways for pre-diabetes and type 2 diabetes and have collaborated with the American Academy of Physician Associates (AAPA), the Endocrine Society, the American Academy of Family Physicians (AAFP), and the American Association of Nurse Practitioners (AANP) to develop enduring CME curriculum on diabetes management. Locally, I have collaborated and published educational research abstracts and poster presentations with several Yale faculty for the Obesity Society, the American College of Lifestyle Medicine and for the Yale Medical Education conference on novel obesity, transgender care and lifestyle medicine curriculum respectively.

Overview
Jonathan Weber helps patients with diabetes at Yale Medicine’s Diabetes Center manage all aspects of their disease. He specializes in treating patients with kidney issues or other complications caused by diabetes.
“Working together with patients to find the best solutions to help them manage their diabetes and prevent diabetes-related complications is very rewarding,” Weber says.
He says he enjoys helping patients take steps to gain more control over their diabetes and make lifestyle changes such as eating healthier or exercising more to improve their overall health.
“I am interested in sharing what we know about lifestyle medicine along with current and emerging prescription therapies that meet patients’ needs and fit best into their lives,” he says. “The burdens that come with any chronic disease can be challenging. With a consistent and strong ‘therapeutic alliance’ between the patient and provider, I believe we can overcome any challenge together.”
Weber has practiced internal medicine for more than two decades in the Yale New Haven Health system.
