Hello, I'm new to the Physics Forums website. I am in my 5th (and last) year of undergraduate Electrical Engineering, and am planning on applying for a PhD in some computational field. I'm not sure, however, what specific field I want to go into, and I was hoping someone could give me some suggestions. Here is a layout of what I am thinking and why... How do I know I want to do computational research? I have been working with a business doing experimental material science research for a little over a year. I really enjoy the research process, but I have found that I can tolerate a full days worth of coding more than a full days worth of lab work. I often keep a few hands-on projects at home to work on in my free time, which is why I thought I originally wanted to do lab work, but I think I would rather keep the tinkering as a hobby. Of course, it goes without saying, I really have a passion for numerical work. I have had classes in Numerical Analysis, Data Analytics, Math Modelling etc... and I enjoy those courses the most. I can't get enough of this stuff. What am I looking for in my research? I want to apply current numerical techniques to create simulations to answer science questions (the subject is where I need help deciding). I want to analyze experimental data to help build better models and more accurate simulations. I hope to find a science that will call for collaboration with experimentalists, uses skills that easily translate to similar work in industry, and allows me to be versatile in my research (no pigeonhole). I hope this makes sense What are my favorite courses/topics so far? In no particular order... Numerical Analysis, Linear Algebra, GPS Design, E&M, Probability and Statistics, Radio Wave Propagation, Control Systems. My first thought was to look at plasma physics, since I enjoyed a lot of courses that serve as a foundation for it. Unfortunately, my school does not offer a plasma physics course for undergraduates, but I have studied it a little, and recently started working through a textbook. Part of me is also interested in biology/medical related research, but I have very little background knowledge of this field. My interest comes from very frequent conversations with a close friend that has a Biology degree. Let me know if I can add anything, or if something isn't clear. Thank you!
