Thomas W. Reps is the
J. Barkley Rosser Professor & Rajiv and Ritu Batra Chair in the
Computer Sciences Department of the University of Wisconsin, which he
joined in 1985.
Reps is the author or co-author of four books and more than one
hundred eighty papers describing his research (see
His work has concerned a wide variety of topics, including
language-based program-development environments,
the use of program profiling in software testing,
and attribute grammars.
Professor Reps received his Ph.D. in Computer Science from Cornell
University in 1982.
His Ph.D. dissertation won the 1983
ACM Doctoral Dissertation Award.

His collaboration with
Professor Tim Teitelbaum
at Cornell University from 1978 to 1985 led to the creation of two
systems—the Cornell Program Synthesizer and the Synthesizer
Generator—that explored how to build interactive programming tools
that incorporate knowledge about the programming language being
supported. The systems that they created were similar
to modern program-development environments, such as
Microsoft Visual Studio
but pre-dated them by more than two decades.
Reps is President of GrammaTech, Inc.,
which he and Teitelbaum founded in 1988 to commercialize their research.
From 1985–2014, Professor Reps was the co-leader, with
Professor Susan Horwitz—until she
passed away in 2014—of a
at the University of Wisconsin that has carried
out many investigations of program slicing and its applications in
recent work concerns program analysis, computer security, and
software model checking.
In 1996, Reps served as a consultant to DARPA to help them plan a
project aimed at reducing the impact of the Year 2000 Problem on the
U.S. Department of Defense.
In 2003, he served on the F/A-22 Avionics Advisory Team, which provided
advice to the U.S. Department of Defense about problems uncovered during
integration testing of the plane's avionics software.
Reps's 1988 paper on interprocedural slicing, with
and his then-student David Binkley,
was selected as one of the 50 most influential papers from the ACM SIGPLAN
Conference on Programming Language Design and Implementation (PLDI), 1979-99.
the 1988 paper and the subsequent journal version
have received over 2,100 citations.
His 2004 paper about analysis of assembly code,
with his student Gogul Balakrishnan,
received the ETAPS Best-Paper Award for 2004 from the
European Association for Programming Languages and Systems (EAPLS).
His 2008 paper about a system for generating static analyzers for machine instructions,
with his student Junghee Lim,
received the ETAPS Best-Paper Award for 2008 from EAPLS.
In 2010, his 1984 paper ``The Synthesizer Generator,''
with Tim Teitelbaum, received an
ACM SIGSOFT Retrospective Impact Paper Award.
In 2011, his 1994 paper ``Speeding up slicing,''
with Susan Horwitz, Mooly Sagiv, and Genevieve Rosay, also received an
ACM SIGSOFT Retrospective Impact Paper Award.
Reps's sixteen papers in ACM Transactions on Programming Languages and Systems (TOPLAS)
run to more than 800 pages.
Five of his students, Gogul Balakrishnan, Akash Lal, Junghee Lim, Aditya Thakur, and Venkatesh Srinivasan,
have been recipients of the Outstanding Graduate Student Research Award given by
the University of Wisconsin Computer Sciences Department.
Akash Lal was also a co-recipient of the
2009 SIGPLAN Outstanding Doctoral Dissertation Award,
and he was
one of the 18 awardees
selected for the
2011 India TR-35 list
(top innovators under 35).
In 2003, Reps was recognized as a
``Highly Cited Researcher''
in the field of Computer Science—one of 230 worldwide who received such
recognition by the
Institute for Scientific Information.
As of June 2014, Reps was ranked 4th (field rating) and 7th (citations) on Microsoft Academic Search's
most-highly-cited authors in the field of Programming Languages,
and 13th (field rating) and 23rd (citations) on its
list of most-highly-cited authors in the field of Software Engineering.
Reps has also been the recipient of an NSF Presidential Young
Investigator Award (1986), a Packard Fellowship (1988),
a Humboldt Research Award (2000), and
a Guggenheim Fellowship (2000).
He is also an ACM Fellow (2005).
In 2013, Reps was elected a foreign member of
Reps has held visiting positions at
the Institut National de Recherche en Informatique et en Automatique (INRIA)
in Rocquencourt, France (1982-83),
the University of Copenhagen, Denmark (1993-94),
the Consiglio Nazionale delle Ricerche in Pisa, Italy (2000-2001), and
the University Paris Diderot—Paris 7 (2007-2008).
