Not in CS, it was in Systems Design Engineering. My Ph.D. was more mechanical than anything. My Master's had a big CS component as I was affiliated with the computer graphics lab (my Master's co-supervisor was part of the lab until he retired to look after his wife). I did most of the numerical CS courses and all the CS computer graphics courses.

There's not much call for my particular skill set, unfortunately. I interviewed for a position in Google X, but it was a very strange interview and I didn't get past that, despite giving a very thorough answer for the pre-interview problem they posed.
