Tim Teitelbaum's research is focused on automatic program analysis with the ultimate goal of solving the important cyber-security concerns of the modern world. Making the cyber-world a safer place includes uncovering bugs and vulnerabilites in software that can be exploited by attackers around the globe.

To protect software from attacks optimally, we must analyze both source code and machine code during software development. Analzying source code is critical for developers to understand the vulnerabilities that may exist in the code they are writing. Analyzing machine code allows organizations to scan components of code, such as libraries or full applications, using stripped executables. By analyzing the code as it will be executed in the final application, we are able to achieve deeper insight than would be attainable from analysis of source code alone.

Dr. Teitelbaum retired from Cornell in June 2011 to devote his time to GrammaTech, Inc., where he is the CEO. He continues to pursue both his research interests and the transition of research to commercial products.
