The purpose of the NHGRI Predoctoral to Postdoctoral Transition Award for a Diverse Genomics Workforce (F99/K00) is to support a defined pathway across career stages for talented graduate students from diverse backgrounds, including those from groups underrepresented in biomedical, clinical, behavioral and social sciences. This two-phased award will facilitate completion of a doctoral dissertation (F99) and transition to a strong postdoctoral research position (K00) focused on the scientific, medical, ethical, social and/or legal areas of genomics research. It is anticipated that successful completion of this phased award program will have provided students sufficient scientific and career development activities to set them on the path to becoming independent genomics researchers. This Funding Opportunity Announcement (FOA) does not allow applicants to propose to lead an independent clinical trial, but does allow applicants to propose research experience in a clinical trial led by a sponsor or co-sponsor.
