I got my master's in Computer Science 3 years ago. I had a poor GPA of 3.3/4. I wanted to get a job back then and I was not that interested in the coursework. I am currently working as a software developer at a well-known company. And of late, I have been seriously thinking about becoming a researcher.
I live about an hour away from the college where I got my master's. There were two to three professors whose work I found to be interesting. I read a few papers that their groups produced, I know what problems they are solving. Now, how do I actually approach a professor and ask him if I could work in his lab parttime or work on some project with him? My goal is to ultimately get a Ph.D. admission. To that end, none of my professors would remember me well enough to write me a LOR. My only hope right now to work on a research project with a professor and hope he would get me a Ph.D. admit. How do I start the initial conversation? Should I email him and ask him if I could meet him for half an hour to get some career advice?
