I want to do some ugrad research. I am a senior (but with 2 years left before I graduate) electrical engineering/physics dual major. I am looking for profs at UM ann arbor and Wayne State U to do research for (I do not attend one of these universities.) I am interested in electromagnetics, photonics/optics, and solid state electronics/physics. However, I don't have any idea of a specific area in these fields I want to get into (should I have an idea???) All I know is I really enjoyed electromagnetics (possibly my favorite class I have taken yet), and I an in optoelectronics right now and really enjoy it. Next semester I am taking solid state physics and a solid state technology course along with optics/lasers/microscopy (and hopefully another semester of electromagnetics or an antennas and radiation theory class). So, after the spring I will have some relevant coursework under my belt. I am looking through all of the professors at UM ann arbor in the areas that are of interest to me and the list is daunting. What should I look for in a mentor? Are there hints I should pick out to determine if the person is right for me and I'm right for them? I certainly can't read the papers of all the professors. So, any hints on how to pick out a research mentor for a summer REU??? Do I need to have a research topic in mind ahead of time? Do I need prior coursework or extensive background in the area I am interested in doing research in?
