Know how academically successful and respected A professor is I have a lot of professors, and I want to have a way to know how respected and successful academically speaking each one of them is. 

The reason is that some professors talk very highly about themselves and it seems that they are very good at what they do but I suspect it sometimes isn’t the case.
I want to go work at the summer in the university under some professor and I want to try to get accepted my someone who really does interesting things.

I tried searching for a professor rank system or something similar online but I didn’t find anything. Does some ranking system even exists?

I also tried looking on the published papers of some professor, I saw a lot of papers but how can I know if they are of quality or low level and meaningless.

Thanks

You could check the H-Index, but since most indexes accumulate points overt ime, older persons are having an andvantage


Most probably, it does not make too much of a difference how good the reputation of your professor is as long as you are getting good guidance. Ask former students how good the support was and how interesting the topics were.
