Postdoctoral fellowships support research, and frequently career development training, to enhance your potential to becoming a productive, independent investigator. Securing a fellowship sends a strong signal that you are capable of conducting fundable research and will likely lead to successes with larger grants. Writing a fellowship will also increase your productivity and impact because you will learn and refine skills necessary to articulate your research priorities. However, competition is fierce and your fellowship application needs to stand out among your peers as realistic, coherent, and compelling. Also, reviewers, a committee of experts and sometimes non-experts, will scrutinize your application, so anything less than polished may be quickly eliminated. We have drawn below ten tips from our experiences in securing postdoctoral fellowships to help as you successfully tackle your proposal.
