I am in the process of choosing the topic for my thesis. Originally I came from a more theoretical branch of physics but I realized that I do not see my future in university research, but more in the industry. I want to do research with more direct applications, but now I am not sure what my interests really are. Would you rather go into material sciences, optics/laser research, solid state physics/condensed matter physics or a completely different area? May be medical physics? Which industry has the potential to be “future-proof” ? At this point research in the area of optics /applications of lasers seem quite interesting to me, but I am not sure. This is my main problem, I am not sure in which direction I want to go. I would be really thankful to opinions from experienced physicists. Do you love your job, is it interesting and challenging or would you choose differently if you had the chance?
