  The Office of the Scientific Director is responsible for programmatic oversight, review, and administration of the intramural research program at NHLBI.  The Office has several key functions including:
  • Planning, coordinating, and directing the basic and clinical scientific research programs conducted within the Division of Intramural Research (DIR)
  • Encouraging implementation of new technologies, application of new techniques and treatments through clinical trials, and promoting research collaboration
  • Serving in an advisory role to the Center and Branch Chiefs and Institute Director
  • Developing and maintaining the necessary scientific capability in the Division to foster and guide an effective research and clinical program

Participating in the planning and directing of institute resource allocation and providing senior level administrative support to the DIR programs.

The Office of the Clinical Director (OCD) serves to support the mission of the NHLBI Intramural clinical program by conducting outstanding investigator-initiated research, discovering mechanisms of disease and developing novel devices, diagnostics, and therapies to benefit patients. The OCD is responsible for the oversight of the clinical research portfolio of the NHLBI’s Division of Intramural Research. 

As part of this oversight, the OCD develops and implements policies related to the conduct of human subjects research; ensuring that the clinical research programs of the Division are consistent with the overall mission of NHLBI and NIH; ensuring compliance with NIH and DHHS policies for the conduct of clinical research; overseeing in-patient and out-patient clinical programs, and ensuring the scientific integrity and quality of the clinical research and clinical care conducted by NHLBI staff. The OCD works directly with and supports the Scientific Review Board, the Institutional Review Board, and the Data Safety and Monitoring Board to ensure that the highest standards of clinical research are met. 

The OCD is the interface between the NHLBI and the NIH Clinical Center which houses the inpatient units and clinics where patients are treated on intramural NHLBI clinical trials. The Clinical Director exercises medical direction and supervision of all clinical services and assures the quality of medical care delivered to patients treated on NHLBI clinical trials.

One of the most important activities of the OCD is to manage a comprehensive infrastructure supporting and facilitating the intramural clinical research program including research nurse education and training, protocol navigators, data managers, trial monitors, a DIR clinical research database, an office of protocol recruitment, and bio-statistical support for trial design and analysis. These efforts are intended to ensure that all investigators within the DIR conducting clinical research are compliant with regulations guiding good clinical practice and are supported in their endeavors with an outstanding research support system and to promote the recruitment and retention of talented young investigators wishing to conduct investigator-initiated clinical research at the NHLBI.

The NHLBI DIR’s clinical research program is one of the largest within the NIH supporting more than 180 active clinical research protocols, 650 inpatient admissions resulting in 5,700 patient/days in the Clinical Center and 14,000 outpatient visits.

The Office of Education is dedicated to promoting the success of all NHLBI scientists, both as trainees and as mentors of trainees. Specialized programs provide research training for high school students, college students, graduate and medical students, postdoctoral fellows, and clinical fellows. The Office provides mechanisms for trainees to learn each of the skills required for success in their chosen field. NHLBI is committed to improving the representation of underrepresented groups, including minorities, women, and scientists with disabilities in the mainstream of basic and clinical research.

The Scientific Information Office works with investigators and core facility heads as well as the DIR as a whole to strategically determine their computing needs, and develops short-term and long-term plans to meet these needs.

The Office is responsible for researching, securing, custom designing, and applying cutting edge IT solutions, products and support in order to facilitate variety of biomedical computing needs ranging from computations, to data storage, to support in the clinical setting. In addition, the Office collaborates with sources outside the DIR including the Center for Biomedical Informatics within the Office of the Director, NHLBI, the Center for Information Technology, NIH, and the Department of Clinical Research Informatics in the NIH Clinical Center as well as outside vendors.

The Scientific Information Officer is directly responsible for representing the IT interests of the DIR to NHLBI and NIH-wide committees and workgroups, and collaborates broadly across the organization with basic and clinical researchers.

There are three components to the NHLBI Animal Program Division that work together to support the NHLBI research program.

Animal Program:

Animal Program operations are directly overseen by Dr. James “Buster” Hawkins. It provides care and technical services for NHLBI research animals including: husbandry, purchasing, health monitoring, animal import/export, mouse rederivation and cryopreservation services. We also provide support for NHLBI animals in other NIH facilities. The main phone number is 301-496-5927.

For the NHLBI ACRF Tower animal facility issues and information about animal purchases call 301-496-4801.

For inquiries about the import, export, rederivation and cryopreservation of rodents call 301-451-6744.

Animal Surgery & Resources (ASR):

The ASR services for NHLBI research animals include: animal model development, surgery, surgical support, post-operative care as well as technical services such as radiography, blood & tissue collection, hematology, and blood chemistries.


Murine Phenotyping Core:

Provides cardiovascular, metabolic, pulmonary, neuromuscular and behavioral phenotyping primarily for mice but also other species.
