Thomas W. Reps (born 28 May 1956, United States) is an American computer scientist known for his contributions to automatic program analysis. Dr. Reps is Professor of Computer Science in the Computer Sciences Department of the University of Wisconsin–Madison, which he joined in 1985. Reps is the author or co-author of four books and more than one hundred seventy-five papers describing his research. His work has covered a wide variety of topics, including program slicing, data-flow analysis, pointer analysis, model checking, computer security, instrumentation (computer programming), language-based program-development environments, the use of program profiling in software testing, software renovation, incremental algorithms, and attribute grammars.

A computer scientist is a person who has acquired the knowledge of computer science, the study of the theoretical foundations of information and computation and their application.

University of Wisconsin–Madison Public university in Wisconsin, USA

The University of Wisconsin–Madison is a public research university in Madison, Wisconsin. Founded when Wisconsin achieved statehood in 1848, UW–Madison is the official state university of Wisconsin, and the flagship campus of the University of Wisconsin System. It was the first public university established in Wisconsin and remains the oldest and largest public university in the state. It became a land-grant institution in 1866. The 933-acre (378 ha) main campus, located on the shores of Lake Mendota, includes four National Historic Landmarks. The University also owns and operates a historic 1,200-acre (486 ha) arboretum established in 1932, located 4 miles (6.4 km) south of the main campus.

In computer programming, program slicing is the computation of the set of program statements, the program slice, that may affect the values at some point of interest, referred to as a slicing criterion. Program slicing can be used in debugging to locate source of errors more easily. Other applications of slicing include software maintenance, optimization, program analysis, and information flow control.

Contents

Reps’s current work focuses on static analysis of stripped (binary) executables, and methods that—without relying on symbol-table or debugging information—recover intermediate representations that are similar to those the intermediate phases of a compiler creates for a program written in a high-level language. The goal is to provide a disassembler or decompiler platform that an analyst can use to understand the workings of COTS components, plugins, mobile code, and DLLs, as well as memory snapshots of worms and virus-infected code.

Static program analysis is the analysis of computer software that is performed without actually executing programs, in contrast with dynamic analysis, which is analysis performed on programs while they are executing. In most cases the analysis is performed on some version of the source code, and in the other cases, some form of the object code.

Machine code set of instructions executed directly by a computers central processing unit (CPU)

Machine code is a computer program written in machine language instructions that can be executed directly by a computer's central processing unit (CPU). Each instruction causes the CPU to perform a very specific task, such as a load, a store, a jump, or an ALU operation on one or more units of data in CPU registers or memory.

Executable file that can be run by a computer

In computing, executable code or an executable file or executable program, sometimes simply referred to as an executable, causes a computer "to perform indicated tasks according to encoded instructions", as opposed to a data file that must be parsed by a program to be meaningful.

Reps is President and Co-founder of GrammaTech, Inc.

GrammaTech is a software-development tools vendor based in Ithaca, New York. The company was founded in 1988 as a technology spin-off of Cornell University. They now develop CodeSonar, a static analysis tool for source code and binaries, and perform cyber-security research.

Awards and honors

Reps has been the recipient of the following awards:

The Association for Computing Machinery (ACM) is an international learned society for computing. It was founded in 1947, and is the world's largest scientific and educational computing society. The ACM is a non-profit professional membership group, claiming nearly 100,000 student and professional members as of 2019. Its headquarters are in New York City.

National Science Foundation United States government agency

The National Science Foundation (NSF) is a United States government agency that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about US$7.8 billion, the NSF funds approximately 24% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing.

The Presidential Young Investigator Award (PYI) was awarded by the National Science Foundation of the United States Federal Government. The program operated from 1984 to 1991, and was replaced by the NSF Young Investigator (NYI) Awards and Presidential Faculty Fellows Program (PFF).

In computer science, pointer analysis, or points-to analysis, is a static code analysis technique that establishes which pointers, or heap references, can point to which variables, or storage locations. It is often a component of more complex analyses such as escape analysis. A closely related technique is shape analysis.
