Query Master Amit Singhal Delivers
Google Fellow Amit Singhal oversees Google's ranking algorithm. That means, his team decides which documents best match a search query.
Singhal, who received his master's degree in computer science from UMD in 1991, heads up the Search Quality department at Google headquarters in Mountain View, Calif. He joined Google in 2000 and has received the title Google Fellow, designating him as one of Google's most accomplished engineers. His team is in charge of Google’s secret sauce. They make Google more effective by writing mathematical formulas that decide Google's search ranking. They're also vigilant in deflecting the constant barrage of spam threats.
RANKING THE DATA
It is Singhal's job to rank sites according to relevance. "Then the real work comes in," Singhal says. "You give me a query, and I give you the top few pages among billions of pages we have indexed. That's where the art of ranking lies. I am part of that aspect of Google." Just ranking those pages is not enough, Google has to figure out how to display these pages to users. "There is lots of interface research at Google," he said. Finally, Google has to do all of this, millions of times a day within milliseconds.
Is there a secret? Not really — Singhal's team simply approaches the problems from every possible vantage point.
Google researchers are also forging into the realm of video, images and audio information, in order to provide users with surprising and delightful information, making Google and Singhal the masters of query.
Singhal was born in India in the state of Uttar Pradesh. He spent most of his boyhood in the foothills of the Himalayas. He has a B.S. degree in Computer Science from University of Roorkee in India, a M.S. in Computer Science from UMD, and a Ph.D. in Computer Science from Cornell University. He worked at AT&T Labs from 1996-2000. Singhal was inducted into the UMD Academy of Science and Engineering on Friday, Oct. 3, 2009.
