Background Koc University 2002-curr.
Associate Professor of Computer Engineering at Koc University College of Engineering. Served as the director of the Computer Information Technology Department during 2009-2011 and 2013.

InQuira, Inc. 2000-2002
Co-founded InQuira - a company that leverages my patent-pending natural language processing technology to provide human interaction solutions for large enterprises. Served as Chief Scientist and VP of Research and Development. InQuira was acquired by Oracle in 2011.

Ascent Technology, Inc. 1999
Worked as a Development Scientist at Ascent - A company founded by Patrick Winston and other members of the MIT AI Lab to apply the results of advanced research to the solution of complex resource planning, scheduling, allocation, and situation-assessment problems. Developed Java applications for airport resource planning incorporating Queuing Theory.

Massachusetts Institute of Technology
Department of Electrical Engineering and Computer Science
1988-1999

Postdoctoral Research Associate
1999
Working with Boris Katz and the Infolab Group on the development of the START question answering system.

Doctor of Philosophy in Computer Science
1998
PhD dissertation: Discovery of Linguistic Relations Using Lexical Attraction. Advisors: Patrick Winston, Marvin Minsky, and Boris Katz. Minor in Brain and Cognitive Sciences. Area exam concentration on the Cyc knowledge based system.

Master of Science in Electrical Engineering and Computer Science
1994
Master's thesis on genetic algorithms and optimization. Developed the numerical optimization algorithm Dynamic Hill Climbing .

Bachelor of Science in Electrical Engineering
1992
Bachelor's thesis on genetic algorithms. Research projects in computer vision, digital design and artificial intelligence. Minor in Economics . Worked as an undergraduate research assistant at the AI Lab on genetic algorithms, mobile robotics and machine vision.

Research Computational Linguistics
Developed the Lexical Attraction Theory of linguistic knowledge. The theory attempts to explain how an agent without prior linguistic knowledge can learn to identify linguistic relations using information theoretic measures in example sentences. My program was able to achieve the best unsupervised language learning results published to date. Worked on the START question answering system developed by Boris Katz. Developed Omnibase, an information extraction system that can respond to database queries using arbitrary knowledge sources on the Web.


Numerical Optimization
Studied Genetic Algorithms with Patrick Winston analyzing population diversity and the problem of local optima. The result was the numerical optimization algorithm Dynamic Hill Climbing, which has found practical applications ranging from medical imaging to neural network training, satellite positioning, molecular energy minimization and regression in econometric models.

Computational Economics and Finance
Founded Redfire Capital Management Group with Michael de la Maza in 1995 with the purpose of developing agent-based computational models in economics and finance based on artificial intelligence techniques. The company currently has an active research contract in computational economics. Organized two workshops in 1998: Artificial Life VI Workshop on Agent-based Economics and the First Workshop on Agent-based Modeling of Financial Markets.

Other
Machine Vision: Worked in the machine vision group of Berthold Horn as an undergraduate research assistant developing image processing utilities. Had a short term position in the University of Hawaii to develop X windows utilities for vision research with Shahriar Negahdaripour.
Mobile Robotics: Worked in the mobile robot group of Rodney Brooks designing the TV circuitry for the robot Attila. Attila was a precursor of Sojourner, the robot NASA sent to Mars in 1997.
Computer Chess: Worked with David McAllester developing the ABC-Search chess algorithm. The world champion chess program Socrates used some of our techniques successfully.
