Can dietary interventions change how fast genomes accumulate mutations with age?
We studied how caloric restriction (CR)—one of the most robust lifespan-extending interventions—affects somatic mutations across the genome in different tissues and cell types in mice.

Feeding Mice Fewer Calories Reduces DNA Mutations
A new NYU Langone study showed that feeding mice 30 percent fewer calories reduced the level of genetic mutations across several tissues.

Do very different types of neurons differ in their rates and patterns of somatic mutation?
We profiled somatic mutations in human cerebellar Purkinje neurons (PNs), one of the largest cells in the body, and granule neurons (GNs), one of the smallest.

Cooper is fed up with the MTA. Morning commute issues, afternoon commute train rerouted back to Manhattan. 2 hours later still not home.

This pair of ravens was like a pair of humans. If they could speak I’m sure they would have many tales to tell.

It was a pleasure to present my work at the DNA, mutations, and cancer Gordon Conference in Ventura, CA. Amazing people and great science set in a beautiful place. #GordonConference #Ventura
