OH, just found this and it seems appropriate since I'm new :)
I've got a master's degree in Biology (plant ecology) and another in Biostatistics, and have worked for 8 years as statistician and do whatever it takes to get and report on data for a transplant center (liver & kidney, mostly). I'm currently taking the first/overview course for a new program a the university where I work for a PhD in Biological Complexity, which is an offspring of their BioInformatics MS program. I haven't formally applied yet - I'd planned to wait until I'd taken all of the courses that I could as special student since I have 3 kids under 4, but my professor is encouraging me to go ahead and apply and says the 7 year rule wouldn't be strictly enforced.
My interests are pretty broad ranging - ecology, evolutionary biology, complexity, genomics, physics, astronomy, anthropology, archaeology, modeling all of the above, philosopy/metaphysics, logic, etc etc etc :)
