  • C.N.H. Long Professor of Immunobiology and of Medicine (Endocrinology)

    My background and research are in translational immunology. I am interested in understanding the basis for autoimmune diseases and developing new therapies based on our understanding of disease mechanisms. My focus has largely been in the field of autoimmune Type 1 diabetes. The work encompasses basic laboratory work as well as clinical studies to understanding the regulation of autoreactive T cells to clinical trials that involve novel therapeutics. As part of these studies my lab has been very interested in analysis of beta cell function in Type 1 diabetes and identifying the cellular mechanisms that can protect them from immune killing. We have also been studying the development of autoimmune diabetes in patients with cancers who are treated with checkpoint inhibitors. Our clinical and basic studies are focused on understanding how beta cells are destroyed and react to inflammation. Finally, with the COVID-19 pandemic, we have been studying the immunologic basis for responses in children and adults who are hospitalized with COVID-19 to understand the mechanisms that can lead to disease protection.
  • Associate Professor of Medicine (Endocrinology)

    Dr. Raimund Herzog is an Assistant Professor in Endocrinology at Yale School of Medicine. He received his M.D. from University of Ulm, Germany before moving to the US, where he pursued his training in Internal Medicine at Yale School of Medicine. He earned his M.H.S. in the YCCI Junior Faculty Scholars program while further specializing in Endocrinology at Yale. In addition to caring for patients at the Yale Diabetes Center and teaching medical students Dr. Herzog maintains an active translational research program. A physician scientist with a strong interest in neuroscience and diabetes, Dr. Herzog’s laboratory is focused on characterizing and preventing its central nervous complications. He uses state-of-the-art technologies like in vivo NMR spectroscopy and phospho-proteomics to define the impact of diabetes and intensive insulin treatment on brain metabolism and cognition. His work extends from cell culture and animal models all the way to translation of findings to human subjects. It has produced novel insights into the molecular mechanisms underlying brain energy substrate metabolism thereby laying the basis for the development of targeted therapies that will protect the brain from diabetes complications and injury. In a related area Dr. Herzog’s workgroup has engaged in several collaborative projects that apply his understanding of metabolism towards more comprehensive and unbiased metabolomic analysis of peripheral plasma metabolites in an obese and diabetic adolescent cohort. Furthermore he is exploring the role of circulating small molecules and lipids in the context of aging-related cognitive decline in a cohort of elderly subjects. As part of his studies he has established a close working relationship with the Magnetic Resonance Research Center, Keck Mass Spectrometry Center and the Biostatistics Resource at Yale. His studies are funded by several NIH and private foundation awards and have resulted in high impact publications in journals like The Journal of Clinical Investigation, Diabetes and Endocrinology.

Functions of the Administrative Core

The Administrative Core is designed to coordinate and support the activities of the Diabetes Research Center. The Core operates under the supervision of co-Directors Dr Gerald Shulman and Dr Kevan Herold, and is accessible to all of the members and personnel participating in the DRC. The principle functions of the Core are:
  • Administrative and Financial Management
  • Provision of Research Support Services
  • Administration of the Pilot and Feasibility Project Program
  • Provision of a Scientific Enrichment Program

Grant Management

The DRC Administrator is directly responsible for maintaining fiscal records and coordinating the personnel involved in its Scientific Cores. The Administrative Core supervises all purchases related to the Center budget and maintains accurate monthly statements of these budgets for distribution to the Core Directors/Co-Directors and to the University's Grant and Contract Administration. Budgets are monitored to assure that there is no budgetary overlap between the DRC and the grants of individual users of Core resources. In addition, it monitors all fees for DRC Cores. The staff is responsible for the preparation of all required reports concerning the activities of the DRC, including competing and non-competing renewal applications.

Coordination and Review

A key function of the Core is to facilitate the Director's activities as overseer of the Scientific Cores, the Pilot and Feasibility (P&F) Program, and the overall progress of the Center. Data on the use and services of the Cores are evaluated regularly. The administrative core plans and coordinates regular administrative meetings of the Executive Committee, the P&F Oversight Committee, and prepares reports on the discussions and decisions of the Committee. The staff also is responsible for planning and organizing visits by members of the DRC's external Advisory Board.

Pilot/Feasibility Program

The Core is responsible for organizing the review of Pilot/Feasibility Project applications and for budgetary oversight of the funded applications. They provide support to the grantees and collect data on the outcomes of the Pilot/Feasibility projects.

Enrichment Program

The Core is responsible for planning and organizing the various DRC Seminar Programs. The staff also prepares a calendar of conferences/lectures in diabetes-related areas that are conducted within the basic and clinical departments of the School of Medicine, including Endocrine “Grand Rounds”, Diabetes Journal Club, Immunobiology Seminar Series, the Cell Biology Conference, among others.There is close interaction with the Division of Endocrinology and other departments at the medical school when there are visitors with shared interests. The Core distributes notification of meetings to all Center members as well as appropriate pre- and postdoctoral trainees.

Informational Services

The Administrative staff is responsible for compiling and updating DRC technical resources, functions and cores activities for distribution to members on its website, including administrative services and services provided by the scientific cores. This allows for efficient access to the DRC and to avoid duplication of resources.

Support of Clinical Translation Core Research

Many of the DRC investigators conduct human research studies that utilizes facilities and resources that are designated for clinical research. The DRC Administrative Core provides support for the operations of these sites collaboratively with the Yale Center for Clinical Investigation (YCCI). The tasks involved are broad and are used for patient recruitment, administrative and regulatory tasks, specialized research services (e.g. imaging), procurement and storage of research samples, and data acquisition from the electronic health record (Epic). The administrative task can also assist DRC investigators in recruitment of underrepresented minorities and women for research studies. This helps to ensure that subjects participating in diabetes-related research projects supported by the DRC are representative of Connecticut's population of non-diabetics, Type 1 and Type 2 diabetic patients and patients with obesity. Our access to and recruitment of minorities is facilitated by the presence of the Yale Primary Care Center, which provides health care to a large segment of the minority community (both African-Americans and Hispanics) in the New Haven area as well as through outreach programs sponsored by the YCCI.

Biostatistical Support

The Administrative Core provides statistical support to DRC investigations. James Dziura, PhD, offers consultative services to DRC members in study design and statistical analysis at no or at reduced cost (depending on requirements). Dr. Dziura is a Professor of Emergency Medicine. Deputy Director, Yale Center for Analytical Sciences and Deputy Director, Yale Data Coordinating Center.

Relationship of DRC to the Institution

The Dean of the School of Medicine, Dr. Nancy Brown, is the institutional official ultimately responsible for the conduct of the DRC. As such, she approves appointments to the External Advisory Committee, and receives reports of Center progress. The Directors of the DRC are responsible for facilitating communications between the Dean, the Executive Committee, the Grant and Contract Administration, the External Advisory Committee and NIDDK.

Financial Management

The Administrative Core carries out financial monitoring of the DRC, on a day-to-day, basis. Although the University has a centralized Grants and Contract Administration Office, the scope of the DRC grant requires continual monitoring of purchases and salary commitments on an ongoing basis within the Center administration for effective utilization of Center funds. The Directors and appropriate personnel receive accurate accounting of expenditures on a monthly basis. The DRC Administrative Core maintains a working relationship with the Grants and Contract Office of the School of Medicine to facilitate fiscal management.

The Administrative Core will monitors the budgets of the Cores and Pilot and Feasibility Projects. The funds for the latter are sent to the applicants primary department and managed there. Budget recommendations will be given to individual PIs concerning provisions for supplies and animals, not available from the Core budget, and where the Core provides personnel and supplies, guidance is given to assure that there is no duplication in individual extramural or intramural grants.
