Funded grant applications

Nearly all of our lab funding has come from the National Institute on Aging (NIA/NIH). We’ve received smaller pilot grants and one foundation contract that are not shared here. Budget sections have been removed in some cases to keep salary information confidential. Some non-PI biosketches were also removed. Score sheets are provided. We hope these serve as useful examples for others. Please do not copy or take anything from these proposals without talking to us about it.

dossier for promotion to FULL Professor

All materials submitted as part of dossier for promotion from associate professor to (full) professor at Duke.

Tenure dossier for promotion to Associate Professor

All materials submitted as part of tenure dossier for promotion from assistant professor to associate professor with tenure at Duke.

Every institution has slightly different expectations for this, but hopefully this is a helpful sample for people working in related fields. Yes, I include figures and photos in many of these documents and maybe that (especially the photos) is unprofessional/unnecessary but I think I’d prefer to have some character in these documents if I’m on a committee reading stacks of them for months. It’s also important to me to humanize the science.

None of this is prescriptive; do your own thing within the bounds of what the expectations are for you locally of course. Ask slightly senior colleagues to share what they submitted for more locally appropriate samples. There is a very helpful summary from Manya Whitaker of things to think about when preparing a dossier for tenure. It’s a lot of work but also a really nice opportunity for reflection on where you’ve been and are headed in the future.

SO MANY people make this happen. One person gets tenure but it takes an awesome number of people to raise one scientist. I’ve had almost 150 co-authors, 5 formal mentors plus 3 other committee members, a half dozen other grant mentors, formal and informal senior colleague mentors in the field, advising from department chairs, voluntary mentorship and support from so many senior colleagues in the field, and all the students and staff that make every bit of this happen. What an incredible debt of mentorship we all owe to future trainees. Looking forward to paying all of this forward for the decades to come!

Nearly 70 current and former members of our research lab have given critical hours of investment into so many projects. This is their research; how lucky that I get to spend my days with them.

So many mentors (even if only slightly senior!) and collaborators who have taught me critically valuable things about research, teaching, and how to do this job and still be a functioning human. Thank you for your inspiration and support!
