ATHERTON, Calif. - Rajeev Motwani, a Stanford University computer science professor who advised one of Google's creators, was found dead in his swimming pool. He was 47.

Stanford University said Motwani apparently drowned on Friday at his home in Atherton, and his friends told the school news service he did not know how to swim.

Motwani's work using algorithms to search vast computer databases, like the Internet, is celebrated in Silicon Valley.

Google co-founder Sergey Brin wrote on his blog that Motwani's counsel played a big role in his research, education, and professional development.
