I hope to help."
Udi became the the man responsible for all of search products back in October 2010 and then in October 2014 he was the VP of engineering at YouTube.
Matt Cutts, the currently on leave search quality lead, responded about his personality and contributions on Twitter:
@amir working behind the scenes != shy. Udi is witty, well-spoken, and always happy to fight the hard battles to do the right thing.

It just seems a lot of people are leaving Google's search team in the past couple years - of course, people are getting older and new people are taking the helm.
