That term is already taken for people who use computers to do science, e.g. physicists doing computational modelling.

Dijkstra preferred "computing science", didn't he?

Now, calling it "science" at all is problematic if you don't consider mathematics to be a science.

My degree is actually in "Computational Science" (University of Hull, England). However they decided to rename it to the standard "Computer Science" the year after I started.

I've seen that in some UK univs they call it Computing. I think that's a better term. One short word, too.
