Maximizing Access to Research Careers (MARC) is a special research training support activity of NIGMS. Its goals are to increase the number and capabilities of scientists from underrepresented groups who are engaged in biomedical research and to strengthen science curricula and student research opportunities at institutions with substantial minority enrollments in order to prepare minority students for research careers.
MARC Undergraduate Student Training in Academic Research (U*STAR) Awards (T34) provide support for students who are members of groups that are underrepresented in the biomedical sciences to improve their preparation for graduate training in biomedical research. These underrepresented groups include:
The program can also support efforts to strengthen the faculty, science course curricula, and biomedical research training programs and infrastructure at institutions with significant enrollments of underrepresented students.
Trainees must be honors students majoring in the sciences who have an expressed interest in a biomedical research career and who intend to pursue postgraduate work leading to a Ph.D., M.D./Ph.D., or other combined professional degree-Ph.D. The period of appointment to the MARC U*STAR Program is 2 years at the junior/senior level.
