Hello, I'm looking to get into grad school for physics, but I've done very little research. I did a little bit of astrophysics research early in my college career and a little bit in the field I want to pursue (nanobiosensor stuff), but nothing substantial. However, after college, I did work in an R&D group for a medical devices company and came up with a product for which I now have a patent. My question is, if I focus on this in my application and my essay and whatnot, is this something admissions committees will look at in a favorable light? Or would it be better to try to do some academic research first before applying to grad school. I have like a 3.5 physics gpa and an 830 on my pgre. Thanks a lot ahead of time for any advice.
