I am in my second year in a MSc that doesn't relate too much with TCS though I wish it would. It's basically about control theory, signals and systems and I took classes in advanced systems (robust, nonlinear, optimal, stochastic), advanced signal processing and convex optimization.
I am trying to figure out a good area to tackle for my dissertation paper and I was wondering whether I can somehow relate to some TCS subject.
The only area that I can think of it could relate is optimization, but I don't have anything particular in mind, the whole subject being very interesting.
It would be great if you could share which topic you think belongs to both worlds.
PS: This question might be totally out of the scope of this Q&A site, so I totally agree if you feel like it's worth closing. Thanks!
