Contributions
- Ocampo et al. 2016 (Cell): cyclic in vivo expression of OSKM (Oct4, Sox2, Klf4, Myc) in mice extended lifespan of a progeroid model and improved tissue function in normally-aged mice — the founding demonstration of partial reprogramming as an anti-aging strategy.
- Multi-organ chimera work and stem-cell biology preceded the aging pivot.
- Central to organizing the intellectual and translational programme at Altos Labs, which recruited him as an inaugural principal investigator.
Style
Developmental-biology-first; his lab bridges stem-cell biology, epigenetics, and aging. Prolific and highly cited; frequently produces attention-grabbing early results that generate follow-up studies.
Why he matters for longevity
The 2016 paper is arguably the most-influential single publication of the current partial-reprogramming wave, catalysing the founding of Altos, Retro, NewLimit, Turn.bio, and others.
