New Mars Forums

I am currently casting around for a masters to do next year in the area of environmental science or ecological engineering.  My BSc was in Ecology, and it included some environmental chemistry, soil sciences and microbiology, amongst other things.  Suppose that a permanent Mars colony was just a few years away and I wanted to study something that would get me on track to be part of the crew as a terraformer or closed ecological system engineer.  What should I study, and where?  Obviously, career choices based on the above assumption should be viewed with extreme scepticism (and then some!), but I would nonetheless be interested in any suggestions people may have.
