Stanford University professor Rajeev Motwani was found drowned in his pool Friday, the Associated Press reported.
Friends told the school news service he did not know how to swim.
Motwani was an unofficial advisor to Sergey Brin when he was studying at the university and developing Google. Brin wrote about him in his blog
"It is with great sadness that I write about the passing of my teacher and good friend Professor Rajeev Motwani. But I would rather not dwell on the sorrow of his death and instead celebrate his life.
Officially, Rajeev was not my advisor, and yet he played just as big a role in my research, education, and professional development. In addition to being a brilliant computer scientist, Rajeev was a very kind and amicable person and his door was always open. No matter what was going on with my life or work, I could always stop by his office for an interesting conversation and a friendly smile.
When my interest turned to data mining, Rajeev helped to coordinate a regular meeting group on the subject. Even though I was just one of hundreds of graduate students in the department, he always made the time and effort to help. Later, when Larry and I began to work together on the research that would lead to Google, Rajeev was there to support us and guide us through challenges, both technical and organizational," Brin blogged.
