S ergey Brin is a Russian-born American computer scientist and technology entrepreneur who, along with his Stanford University classmate Larry Page, co-founded the search engine giant, Google (now part of the parent company, Alphabet). While they were Ph.D. students at Stanford in the late 1990s, they developed the revolutionary PageRank algorithm, which was a new and far more effective way of ranking the relevance of web pages. This technological breakthrough became the foundation of the Google search engine, which they launched in 1998 from a friend's garage.

Google quickly became the world's most dominant search engine, and the company grew into a massive and powerful global technology conglomerate with a vast portfolio of products and services, including Android, YouTube, and Chrome. Brin served as the company's president of technology and later as the president of the parent company, Alphabet, where he focused on long-term, ambitious 'moonshot' projects at the company's research lab, X. He has since stepped back from an executive role but remains a controlling shareholder and a member of the board. He is also a major philanthropist, with a focus on Parkinson's disease research.
