I have been applying to physics grad schools for the past two years, received 0 offers. I'm not sure how or whether I can further improve my profile or if I should try again.
Here is a brief summary: I graduated from a top undergrad program, with 3.7< dpt gpa<3.8. My intended concentration was theoretical cosmology but now I'm open to anything physics related. I took some of the most advanced classes among my cohorts as I started graduate level classes sophomore year (which is probably why my gpa is not >3.9). I have been doing research every summer since before college. I have two publications, one in prd and another in apj. I have perfect gre scores and excellent recommendations. examples of awards include departmental awards every year from my university, US physics olympiad gold medal etc. I am an international male.
I applied to 15 of the top programs (ranked 30th and above) twice in the past two years, received 0 offers. I'm not sure what more I could have done. If I were to try again next year, what can I do to improve my chances? Especially for the admitted students, how do you think I could improve my profile? Do you think I should travel to the schools and bug the profs about their research?
If I don't apply to physics again, what other options do people commonly explore? Anyone with a similar experience?
Thanks!
