I don’t have live access to news feeds right now. Based on recent widely reported information, Stephanie Buttermore, Ph.D., a cancer research scientist and fitness influencer, passed away in March 2026 at age 36; her fiancé Jeff Nippard announced the death and asked for privacy. Reports indicate she held a Ph.D. in Biomedical Sciences with a focus on ovarian cancer mechanisms, and she was known for her YouTube and social media presence documenting her All-In journey.[1][2][3][6][8]
Key takeaways:
- Background: Ph.D. in Biomedical Sciences (Pathology & Cell Biology) from the University of South Florida, with ovarian cancer research focusing on RHAMM as a potential early detection marker.[1]
- Public notices: The death was publicly announced by her fiancé and team on Instagram in March 2026, generating widespread condolences in the fitness and science communities.[2][5]
- Public interest: She combined scientific work with fitness content creation, growing a large following and influencing discussions around evidence-based fitness practices.[8][2]
If you’d like, I can compile a brief timeline of public statements and major milestones, or summarize her scientific contributions in more detail. I can also look for more authoritative obituaries or tributes from scientific institutions if you want.
