I'm honestly baffled by the reaction to this. You're absolutely right that it is extremely clear.

It says he is a director at the Center of Law and the Biomedical Sciences at the School of Law and that he is a Professor (by courtesy) of Genetics at the School of Medicine.

It literally says that in his bio.

Yet at least three people in this thread have felt the need to inform HN that "he's not a genetics prof" and then link to the bio of him that lists him as a Professor (by courtesy) of Genetics at the Stanford School of Medicine.

What does the education portion of your comment have to do with my comment? The comment I was responding to said he was not a Genetics professor, I responded by saying that he is a Genetics professor (according to his Stanford bio).

I wasn't saying that he was not a legal expert as well.
