I'm a Professor in the Department of Computer Science and Engineering at NYU Polytechnic School of Engineering , in Brooklyn, NY. My main research interests are in the area of software testing, including development of software testing tools, and comparing the effectiveness of software testing techniques. My current work in that area focuses on developing techniques for testing database application programs, application security and privacy.
