I'm an MS in CompSci grad who wants to do a PhD someday. The one thing I don't have from my time in undergrad and MS is significant research experience. Of course, I did undergrad research but was never published in any papers. I make a lot as a professional and want to volunteer(read, free) part-time doing research for a professor or lab post-graduation, but I have no idea how to approach this or even find interest amongst professors or labs. Any ideas?
Edit: Undiagnosed disability crippled my undergraduate performance. I was unmedicated, untreated, and had no idea on how to cope. I really managed to redeem myself through my graduate performance and am basically looking for a second chance. If anyone has disability-specific resources as well, that would be great.
