Thank you for the excellent suggestions! I've been working on bigger DoD contracts at my current job, so I'm pretty oblivious to the small company/university grant process.
Since I'm entering Stanford with the intent to obtain a terminal Master's, I'm not sure how much research I'll be allowed or encouraged to participate in. Continuing for my Doctorate is certainly still an option, but I think I'm leaning towards getting my Master's and finding/founding some small company to work with.
Any other insight you have into my situation would be appreciated!
