There's actually remarkably few female biologists in Doctor Who, certainly few that aren't evil mad scientists, and I am not evil. This is even more clear with the companions/assistants, where I've got a choice between Liz Shaw, Nyssa and Martha. And on the topic of the last two ladies, like all biologists, I am most definitely not a medic (never have I been so upset about a character's actual occupation as when it turned out that Owen the Slappable in Torchwood was actually a medic). Which leaves me with Liz. Which isn't too bad, even if she's mostly a physicist, and I am barely a biophysicist.
It's actually an interesting point, because I understand why people get annoyed that a lot of the companions are not brainiacs, that they tend to be the heart of the team, but, for writing/story-telling purposes, it's a lot easier when you have it structured as the person doing the telling and the person being told (see also, Holmes and Watson, Poirot and Hastings), and while it's undoubtedly possible to split these roles, it's difficult. That, to me, was one of the advantages of the shorter but more of them nature of the Old Who Serials, because you could split the Doctor and his companion(s) up, and then give everyone something to do.
