je me demande où il a obtenu ces connaissances d'ailleurs

Il l'a expliqué dans les commentaires :

To be honest, I actually almost selected biology as my major back when I was an undergrad at MIT. I stuck with electronics because I felt I had more of a knack for soldering than pipetting, and I wasn’t much of a risk taker back then. However, I still found the time to take a few biology courses while I was there. The most relevant one was 7.05, Molecular Biology, and the textbook was Stryer’s classic Biochemistry text. It was a great read back then and I’m sure it’s only gotten better. I recommend that as a solid starting point.

The other perhaps not expected answer is that I’ve had several very talented biologists as girlfriends over the years (including my current girlfriend), and I have/continue to learn a lot from them. My girlfriend has the patience to answer my stupid questions about biology, and discussing her research keeps me current. It’s nice to “date up” and to be with someone who can teach you new things.
Aside from that, the only other thing I’ve had to keep me current on my biology knowledge is my subscription to Nature and Science. I love reading these publications, I refer to them as “the fiber in my intellectual diet”; it’s nice to broaden my horizons, otherwise I become too narrow-minded about my work.
