I'm currently a freshman in Biological engineering and questioning my choice of major. At this point, I am about 99.9% sure that I want to go to graduate school. I am currently doing research in computational neuroscience/modeling and I very much enjoy it. The problem is that I feel my true passion is physics. I didn't have Calculus in high school and was therefore hesitant to jump into the physics major, and that is why I chose engineering. Interestingly, it turns out that I am much more interested in math than I had previously thought. Since the intense math behind physics was the determining factor that made me choose engineering, I am having second thoughts. I have also always loved biology and would like to do something relating biology and physics (possibly biomedical optics, biophotonics, etc). Would I be able to go to graduate school for biomedical/electrical engineering with a BS in physics if I carefully choose engineering electives? I feel as though I will always regret not immersing myself in as much physics as possible as an undergraduate... Has anyone gone the BS physics PhD engineering route or vice versa? Also, what are some other physics heavy biomedical engineering emphasis areas? What are some differences between Biophysics and Biomedical engineering? Sorry for so many questions... Thank you for your responses in advance!
