At 71, Richard Brown feels as if he’s a college student all over again.

A nuclear medicine physician turned professor, Brown formally retired in 2020—only to take another job in university leadership the following week and join a venture-backed health care startup. Now, he’s reinventing himself once again, this time as a product entrepreneur—and it has him more excited than ever.
