Matt Kaeberlein | Aging Interventions – Rapamycin, mTOR, CR, Sirtuins, NAD+ & Dog Aging Project



Live Longer World Podcast #5

Dr. Matt Kaeberlein is a Professor of Pathology, Adjunct Professor of Genome Sciences, and Adjunct Professor of Oral Health Sciences at the University of Washington. His research interests are focused on basic mechanisms of aging in order to facilitate translational interventions that promote healthspan and improve quality of life.

Matt has been around the field of aging for a long time and knows more about the work in the aging field than perhaps anyone else. This was a comprehensive conversation where we spoke about how Matt thinks of aging from a functional perspective, caloric restriction and aging, whether NAD+ precursors are effective in slowing aging, the role of sirtuins.

We discuss quite a bit on rapamycin and how it’s shown to be effective in improving the health of mice. Matt is very excited about the potential benefits of Rapamycin in reversing aging and he got me excited too. Matt is also working on the Dog Aging project and in trying to understand aging in dogs.

Finally, we end the conversation by talking a bit on what good scientific practices should look like. Matt approaches his work with an unbiased lens and that’s very respectable.

Matt has a brilliant mind! I had such a blast talking to Matt and I hope you enjoy the conversation as much as I did!
