Marvin Zelkowitz. Marvin Victor Zelkowitz (born 7 August 1945) is an American computer scientist and engineer.

Zelkowitz earned a degree in mathematics from  Rensselaer Polytechnic Institute in 1967 and a master's degree and doctorate in computer science at Cornell University in 1969 and 1971, respectively.
He then taught at the University of Maryland, College Park. While holding a professorship within the Department of Computer Science and 
the University of Maryland Institute for Advanced Computer Studies (UMIACS), he 
was also affiliated with the Fraunhofer Center for Experimental Software Engineering, since renamed The Fraunhofer USA Center Mid-Atlantic (CMA). He is now Professor Emeritus, having retired in 2007.

His early research (1968-early 1980s) was in programming languages. He worked on implementation of programming language features to aid in program development and debugging as well as ways to implement tests for runtime correctness of executable code.

His later research dealt with software engineering practices by looking at developing methods for improving the process of software development.

The years 2003-2009 were devoted to applying these experimental testing results to the field of High-performance computing.

Zelkowitz served as editor of the series Advances in Computers for Academic Press (vols 41-56; 1995-2002) and later 
Elsevier (vols. 57-74; 2003-2008)

Since 1994, Zelkowitz has been active in scientific skepticism as Board member and 
at times Secretary, Treasurer, and President of the National Capital Area Skeptics.
NCAS was founded in 1987 in the Washington, D.C., Maryland and Virginia area and is 
an advocate for science and reason, actively promoting the scientific method,
rational inquiry, and education.
