Sarah Cook is a postbac in the Molecular Development of the Immune System Section of the Laboratory of Immune System Biology. Read Sarah’s postbac spotlight, where she details her postbac experience in the unique setting of the NIH Clinical Center and how this experience has influenced her decision to pursue a career in medicine and translational research.
Postbaccalaureate research trainees (postbacs) at NIAID engage in research at the forefront of immunologic, allergic, and infectious diseases. Postbacs conduct research in NIAID laboratories located in Maryland and Montana (Rocky Mountain Laboratories in Hamilton), which provides a unique scientific research training environment in basic, translational, and clinical research for recent college graduates who plan to apply to graduate or professional school (master’s, Ph.D., M.D., or equivalent graduate degree). Postbacs spend one to two years performing full-time research under the guidance and direction of an NIAID principal investigator. Trainees have the opportunity to engage and network with experts in diverse scientific research fields while taking advantage of the extensive resources of NIH.

Note: The duration of the program is typically one year; however, the fellowship may be extended for an additional year provided satisfactory performance of the trainee and availability of continued support by the laboratory.

"My two years at NIAID were the most important time for my career. I grew the most during this time and as a result, my career development was accelerated greatly. I met great mentors and people who were willing to support me. I had the opportunity to attend diverse and world-class seminars, programs, and conferences that built my resolve in my career path. I am glad I had the privilege to train at NIH and in the Viral Pathogenesis Section of the Laboratory of Immunoregulation at NIAID."
