Mark Manasse joined Microsoft in October 2001.

From 1985 until he joined Microsoft, Mark was a researcher at Compaq's Systems Research Center in Palo Alto, California (previously Digital Equipment Corporation, subsequently Hewlett-Packard and now extinct).

Mark Manasse works in a variety of theory-related areas of distributed computer systems research. He was the inventor of MilliCent (defunct link:; as such, Wired Magazine dubbed him "the guru of micropayments," and was co-chair of the microcommerce working group for the World Wide Web Consortium. Mark has worked on Web search technologies; with Andrei Broder, Steve Glassman, and Jeff Zweig, his work on syntactic similarity was awarded best paper at the Sixth International World Wide Web Conference. Mark was a member the design committee for the Inter-Client Communications Manual for the X Window System. Mark's work on on-line algorithms helped to establish this field, and remains among his most-often cited papers. Mark organized, ran, and developed much of the code for some of the earliest uses of the Internet in distributed computations, when he and Arjen Lenstra factored many large integers, the most noteworthy being the first factorization of a "hard" 100-digit number, and the factorization of the ninth Fermat number.

Mark holds U.S. patents in three of the previously mentioned areas. His doctorate was earned at the University of Wisconsin in Mathematical Logic in 1982, and he spent the following three years at Bell Labs and the University of Chicago.

Mark's projects since joining Microsoft include Koh-i-Noor, PageTurner, Dryad, and a minor role in Penny Black. Additionally, Mark has been working with product groups on MSN Search and with the Windows group on aspects of file systems and storage.

In 1994, Newsweek described Severe Tire Damage (the band Mark founded and for which he plays bass) as "lesser-known" than the Rolling Stones, following STD's unauthorized appearance as the opening act in a multicast performance.
