Born in Jhansi, a city in the state of Uttar Pradesh, India,[12] Singhal received a Bachelor of Engineering degree in computer science from IIT Roorkee in 1989.[13] He continued his computer science education in the United States, and received an M.S. degree from University of Minnesota Duluth in 1991.[14] He wrote about his time at the University of Minnesota Duluth:

UMD was the turning point in my life. Studying Information Retrieval with Don Crouch and then Don recommending that I move to Cornell to study with Gerard Salton, is the main reason behind my success today. Don gave me the love for search, I have just followed my passion ever since.[14]

— Amit Singhal

Singhal continued his studies at Cornell University in Ithaca, New York and received a Ph.D. degree in 1996.[14] At Cornell, Singhal studied with Gerard Salton, a pioneer in the field of information retrieval, the academic discipline which forms the foundation of modern search. John Battelle, in his book "The Search" calls Gerard Salton "the father of digital search." He got interested in the problem of search in 1990 at the University of Minnesota Duluth. After getting a Ph.D. in 1996, Singhal joined AT&T Labs (previously a part of Bell Labs), where he continued his research in information retrieval, speech retrieval and other related fields.[14]


In 2000, he was recruited by friend Krishna Bharat to join Google.[14] Singhal ran Google's core search quality department where he and his team were responsible for the Google search algorithms. According to The New York Times, Singhal was the "master" of Google's ranking algorithm — the formulas that decide which Web pages best answer each user's question.[15] As a reward for his rewrite of the search engine in 2001, Singhal was named a "Google Fellow".[16] Singhal served as the head of Google's core search ranking team[5][6] until his retirement announced on 26 February 2016.[7] It would later transpire that Singhal's departure from Google had occurred after a sexual harassment complaint against him, that an internal review had found "credible".[9]

In 2017, he joined Uber as SVP of Engineering, reporting to CEO Travis Kalanick, and with his fellow Google alum Kevin Thompson operating as SVP of marketplace engineering.[17] He was asked to leave in February 2017 after it emerged that he had not disclosed to Uber the sexual harassment complaint against him that had been responsible for him leaving Google.[9] Singhal's departure from Uber came at a time when Uber was receiving criticism and media attention after allegations by former employee Susan Fowler of a dysfunctional culture of sexual harassment at the company.[18]

Honors and awards

In 2011 he was inducted as a Fellow of the Association for Computing Machinery.[19][20]

Fortune named Singhal one of the smartest people in tech.[21]

In 2011, Singhal was given the Outstanding Achievement in Science and Technology Award at The Asian Awards.[22]

He was elected Member of the National Academy of Engineering.

Google Guice

Google Guice (pronounced "juice") is an open-source software framework for the Java platform released by Google under the Apache License. It provides support for dependency injection using annotations to configure Java objects. Dependency injection is a design pattern whose core principle is to separate behavior from dependency resolution.

Guice allows implementation classes to be bound programmatically to an interface, then injected into constructors, methods or fields using an @Inject annotation. When more than one implementation of the same interface is needed, the user can create custom annotations that identify an implementation, then use that annotation when injecting it.

Being the first generic framework for dependency injection using Java annotations in 2008, Guice won the 18th Jolt Award for best Library, Framework, or Component.

Google Hummingbird

Hummingbird is the codename given to a significant algorithm change in Google Search in 2013. Its name was derived from the speed and accuracy of the hummingbird. The change was announced on September 26, 2013, having already been in use for a month. "Hummingbird" places greater emphasis on natural language queries, considering context and meaning over individual keywords. It also looks deeper at content on individual pages of a website, with improved ability to lead users directly to the most appropriate page rather than just a website's homepage.

The upgrade marked the most significant change to Google search in years, with more "human" search interactions and a much heavier focus on conversation and meaning. Thus, web developers and writers were encouraged to optimize their sites with natural writing rather than forced keywords, and make effective use of technical web development for on-site navigation.
