Okay, it seems that you're supposed to have a specific research idea or a lab figured out when applying for PhD, but in my case, I had a very broad research experience & education during undergrad and it also doesn't help that I'm super indecisive and inquisitive. I applied based on my previous research background rather than research I would like to pursue [which is ill advised I know] and got into a couple programs (both PhD and masters). I've been perusing through many scientific journals, but it's only making me get excited about research areas in my field that sound incredibly interesting. If you had personally struggled with this and could impart some wisdom on how you went about choosing what you are researching now, any tips would be greatly appreciated. Also, what are your thoughts on choosing a research area that you have not had much exposure to during undergrad? Thanks a lot!
