A silly contest involving a TBBT video

This is a video from an episode of The Big Bang Theory, one about the visit to the Large Hadron Collider on the Valentine's Day.



One may see a real-world famous physicist in a big chunk of this video. When I say "famous", I mean "famous" from the media as well as having over 20,000 citations according to SPIRES.




Your task is to find out the name of the physicist.




But you're not allowed to write the name in the comments. Instead, go to Google Scholar and write down the query "firstname lastname" [including the quotes] of the physicist you determined. You will get a list of papers with citation counts.

In the comments, write the largest citation count from the list on Google Scholar that hasn't been written yet. So the first successful commenter writes the number from the first paper, the second commenter from the second paper, and so on. Everyone who knows the right name will know who are the other folks who know the right name. ;-)

The successful ones will ignore the wrong numbers from the unsuccessful ones. Everyone may add other comments aside from the number but not the right name! ;-)
