Prabhakar Raghavan is a business executive and former researcher of web information retrieval. He currently holds the role of Chief Technologist at Google. His research spans algorithms, web search and databases. He is the co-author of the textbooks Randomized Algorithms with Rajeev Motwani and Introduction to Information Retrieval.

Early life and education

Prabhakar was born in Chennai (earlier known as Madras), Tamil Nadu and spent his youth in Bhopal, Madras and Manchester. In 1981, he earned a bachelor degree in electrical engineering from the Indian Institute of Technology Madras, followed by a Master of Science in electrical and computer engineering from the University of California, Santa Barbara in 1982.

Prabhakar continued his education at the University of California, Berkeley, where he earned a Ph.D. in computer science in 1986.

Career

After completing his doctorate, Prabhakar worked in various research positions at IBM. He began as a research staff member at the Thomas J. Watson Research Center. In 1994, he was promoted to manager of theory of computing. A year later, he relocated to the Almaden center in Silicon Valley to become the senior manager of the computer science principles and methodologies department of IBM Research until 2000. His research group focused on algorithms, complexity theory, cryptography, text mining, and other fields. While working for IBM in the late 1990s, he was also a consulting professor at Stanford University.

Raghavan's research team at Stanford co-existed with another researching search engines that included students Larry Page and Sergey Brin, who later founded Google.

After working 14 years at IBM, he became senior vice president and chief technology officer at enterprise search vendor Verity in 2004. In July 2005, he was hired by Yahoo! to lead Yahoo! Research in Sunnyvale, California. At Yahoo!, he worked on research projects including search and advertising. In 2011, he was appointed as Yahoo!'s chief strategy officer by CEO Carol Bartz, who replaced the co-founder Jerry Yang in 2009 and was fired in 2011 as the company declined.

In 2012, Prabhakar joined Google after severe funding cuts in Yahoo!'s research division. In 2018, he was put in charge of Ads and Commerce at Google, and in 2020 he replaced Ben Gomes as head of Google Search and Assistant, amid a push to increase advertising revenue from Google Search. In 2024, he transitioned to the role of Chief Technologist at Google.

Awards and honors

Prabhakar is a member of the National Academy of Engineering and a Fellow of both the Association for Computing Machinery and the Institute of Electrical and Electronics Engineers (IEEE). From 2003 to 2009, Prabhakar was the editor-in-chief of Journal of the ACM.

In 1986, Prabhakar received the Machtey Award for Best Student Paper. In 2000, he was named a fellow of the IEEE; received the Best Paper Award at the ACM Symposium on Principles of Database Systems; and received the Best Paper Award at the Ninth International World Wide Web Conference (WWW9). In 2002, Prabhakar was named a fellow of the ACM. He received the 2006 Distinguished Alumnus Award, UC Berkeley Division of Computer Science. In 2008, Prabhakar was made a member of the National Academy of Engineering, and in 2009, he was awarded a Laurea honoris causa from the University of Bologna. In 2012, he was named a Distinguished Alumnus by the IIT Madras. In 2017, Prabhakar and co-authors received the Seoul test of time award for their 2000 paper "Graph Structure in the Web" at the WWW conference.

Criticism

In April of 2024, Raghavan became the face of declining quality at Google following his takeover of Google search and subsequent focus on ad revenue in the prioritization of search results.
