Heh. Don't worry. My opinion is that everyone in that field acts as if they know something about it. My husband calls it a "P5" discipline..."Pretty Pictures for Pretty imPortant People." And honestly, I agree. The math might be there someday, but right now, it's all about visualization - which actually might be educational to a lot of chemists, and biologists who are working on target development. But I don't think a single drug has come out of it, and probably won't for a long time.
Also, I've never done 3D imagining. My matron-of-honor, however, is one of the most kickass 3D imagers in the country. She's worked on everything from teaching Bradley tanks to see (over 20 years ago) to helping surgeons separate twins conjoined at the scalp (15 years ago) to becoming a Fellow in geophysics at Shell before she was 40 - and with only a bachelors in C.S.
My work has primarily been in natural language processing (speech and text) but there's a whole lot of analysis of large corpora behind that, which is quite akin to infomatics as known in the biotech arena. However, I've just returned to work after five years as a stay-at-home-mom as a real estate agent. Why? Two reasons: more flexibility, and I think I can make more money!
