Okay, so here's the deal. I spoke with my undergraduate adviser yesterday and he gave me the names of several faculty on campus who were looking for undergraduate students to get involved in research. I have contacted both of them and have appointments to speak with them within the next 2 weeks. One professor is involved in theoretical nuclear physics. Currently he is working on projects dealing with neutron stars. The other professor is involved in material research and technology. I am not sure exactly what she is doing but here web page indicates semi and superconductors. Both have expressed much interest in me and from there emails it seems like I have my pick between the two. My question is, does it matter what type of research you are involved in in undergraduate studies? I am hoping to pursue theoretical/ astrophysics in graduate school so the first professor seems like a better opportunity. I am interested in both and if it was possible, would love to get involved with both.
