I actually did not assume based on her name. (There's nothing worse than a correction that is itself wrong.) I tried to find a biography of her in the third person, but could not find one. From her About page, I found out she was a member of Pyladies, which describers itself as an all-woman group. At that point, I felt I did my due diligence.

It really is an important point, not pedantry, to not assume based on names because many cultures have names that sound like the other gender to American ears (and vice versa, no doubt).
