Sergey Brin is an American computer scientist and internet entrepreneur, who, along with Larry Page, co-founded Google Inc in 1998. Brin migrated to the U.S from the Soviet Union, at a young age. He studied mathematics and computer science in college before going to the Stanford University to pursue a PhD in computer science. As a research scholar, his areas of interests included extraction of information from unstructured sources, search engines, and data mining of large collections of data. He met fellow research scholar Larry page with whom he worked on a research project. The two men connected on the intellectual level and started experimenting with their new designs of search engines in the university computers. Initially, their project was called ‘BackRub’, and it was funded through the National Science Foundation. Together Brin and Page developed the PageRank algorithm, which is used by Google to rank web pages. The successful running of their project for many months on the University computers convinced the duo to start their own company. They both put their doctoral studies on hold and with financial investment in the form of a $100,000 cheque from Sun Microsystems co-founder, Andy Bechtolsheim, formally incorporated their company, Google Inc, in California.
