Mark Russinovich

Russinovich was born in Salamanca, Spain and was raised in Birmingham, Alabama, United States, until he was 15, when he moved with his family to Pittsburgh, Pennsylvania. His father was a radiologist and his mother was a business administrator of his father's radiology practice in Pittsburgh. Russinovich is of Croatian descent. He is the grandson of Croatian diplomat Nikola Rušinović.

He was introduced to computers when his friend's father got an Apple II in the 1970s. He reverse-engineered its ROM program and wrote programs for it. At age 15, he bought himself his first computer, a TI-99/4A. About six months later, his parents bought him an Apple II+ from his local high school when it upgraded the computer labs to Apple IIes. He also wrote magazine articles about Apple II.

In 1989, Russinovich earned his Bachelor of Science degree in computer engineering from Carnegie Mellon University, where he was a member of the Pi Kappa Alpha Beta Sigma chapter. The following year he received a Master of Science degree in computer engineering from Rensselaer Polytechnic Institute. He later returned to Carnegie Mellon, where he received a Ph.D. in computer engineering in 1994 with the thesis Application-Transparent Fault Management under the supervision of Zary Segall.

From September 1994 through February 1996, Russinovich was a research associate with the University of Oregon's computer science department. From February through September 1996 he was a developer with NuMega Technologies, where he worked on performance-monitoring software for Windows NT.

In 1996, he and Bryce Cogswell cofounded Winternals Software, where Russinovich served as Chief Software Architect, and the web site sysinternals.com, where Russinovich wrote and published dozens of popular Windows administration and diagnostic utilities including Autoruns, Filemon, Regmon, Process Explorer, TCPView, and RootkitRevealer.

From September 1996 through September 1997, he was a consulting associate at OSR Open Systems Resources, Inc., based in Amherst, New Hampshire. From September 1997 through March 2000, he was a research staff member at IBM's Thomas J. Watson Research Center, researching operating system support for Web server acceleration and serving as an operating systems expert.

Russinovich joined Microsoft in 2006 when it acquired Winternals.

As an author, Russinovich is a regular contributor to TechNet Magazine and Windows IT Pro magazine (previously Windows NT Magazine) on the Architecture of Windows 2000, and was co-author of Inside Windows 2000 (Third Edition). He wrote many tools used by Windows NT and Windows 2000 kernel-mode programmers, and the NTFS file system driver for MS-DOS.
