That was what I was suggesting. A few years ago I was very interested in language design from the perspective of generative programming and type system. I did an extensive literature search, reading the papers and all that. as a side effect I found out which university departments were actively exploring what I was interested in. Out popped Don Batory at U Texas, Krzystof Czarnecki, and work done at CMU and MIT. I recommend this as a way to focus in on what you are interested in and who to work with.
