Premios y Distinciones

  •   NICHD Mentors of the Year category postdoc

    NATIONAL INSTITUTE OF HEALTH

    Estados Unidos, 2014

    The NICHD Mentor of the Year Award is an opportunity to recognize individuals whose mentoring has made a difference in someone’s life at NIH. The two mentoring award categories are fellows and investigators. Nominations were invited from all trainee groups in NICHD, and each nominator had to write a statement, on which the selection committee based their decisions. The selection committee included NICHD clinical and postdoctoral fellows, and postbac fellows.
