I'm about to graduate and I should choose my graduation thesis. My choice will probably determine my PhD area of research so I want to choose wisely. That's why I need some help from guys who are deep in research waters. My areas of interests are solid state physics and plasma physics. My preference is theoretical, but, bottom line is that I will have to do physics for living so this is not too important. My questions are following: What are most researched subjects in fore mentioned areas of physics, ie. where can most grant money (or to rephrase, jobs and research projects) be found? I may also consider working within industry or finance in some later years so I would appreciate any advice considering this possibility. Oh, and to mention that I'm currently in Europe, but that I'm equally interested in prospects in North America.
