That's partially true. But here are a list of labs doing similar research -- the main problem with field is that CS people are gradually depleting from it and supplanted by Mechanical, OR related people.
so if you are from CS background, it is really hard to find a good position (specially in US). I am a also a victim of this condition, done my ugrad theis and masters in evocomp and still no luck for a phd admit -- planning to change my research focus, which is a hard and heart-breaking option for me.
