To work on interesting projects that utilize my capabilities for developing, and implementing complex software systems, especially in the area of wireless games.

Lead all technology development activities for Government funded research group. Activities included algorithm development, hands-on software development, technical management and supervision, proposal generation, new business development, customer interfacing. Specific projects included:

• Agent-based modeling: Developed a Java based simulation platform using fuzzy logic agents for modeling multi-agent systems in military, political, economic, and social domains.
• Multilingual information retrieval. Developed novel algorithms for cross-lingual text retrieval using the HNC Context Vector retrieval technology. Implemented a text processing toolset in C for handling multibyte character sets (e.g. Asian languages) in UTF-8.
• Multimedia information retrieval. Designed and supervised development of a system for content-based image and video retrieval using unsupervised neural network feature detection models.
• Internet shopping agent: Designed and developed a shopbot in Tcl for real-time comparative shopping for books, videos, and other information/entertainment products.
• Intelligent Internet search agents: Designed and supervised development of client-server system of Internet search agents that scour the Web and other online repositories for information of interest to users. System was written in C++ and Tcl/Tk. Personally developed FTP and NNTP agents using Tcl/Tk and Expect.
• Text content exploitation. Designed and developed an early version of HNC’s named entity recognition system using a variation of Hidden Markov Models. Wrote code in Tcl and supervised subsequent development in C.
• Neural networks for information visualization: Designed, developed and supervised development of text content visualization algorithms using unsupervised neural network models in conjunction with the HNC Context Vector text representation technology. Wrote and supervised development of software in C/C++ and X-Motif.
• Bioinformatics: Supervised research work in bioinformatics, including the application of statistical clustering to RNA sequence recognition and the application of stochastic modeling techniques to obtaining robust DNA probes for organism identification.
• Automated fingerprint identification. Designed and developed a system for prefiltering fingerprints in a very large database using Context Vector technology and a novel, fast search technique for high dimensional vector spaces.

• Developed several complex simulations of intelligent aerospace vehicles, including low thrust orbit transfer vehicles, conventional high thrust orbit transfer vehicles, and theater ballistic missile interceptors.
• Developed and implemented several trajectory optimization techniques to optimize trajectories in these simulations.
• Developed novel algorithm for low thrust orbit transfer vehicle guidance using Lyapunov-optimal control theory. Guidance law served as the baseline guidance law for the proposed solar-electric orbit transfer vehicle ELITE, a joint Aerospace Corporation/TRW project.

Taught a course in orbital mechanics and astronautics to Junior and Senior level students in Engineering. Had complete responsibility for the course. Developed all course lectures, homework, and tests and received very positive feedback from students at the end of the course.

• Designed and simulated control systems for spacecraft, including the normal pointing mode controller for the Total Ozone Mapping Satellite (TOMS) and the high gain antenna controller for the Compton Gamma Ray Observatory (GRO).
• Developed interplanetary mission design software to support TRW Mars Rover Sample Return project.
• Developed robust terminal descent guidance law for Mars lander spacecraft using differential game theoretic modifications to E-Guidance algorithm.
• Analyzed interactions between attitude control limitations and guidance strategies for Mars orbit aerobraking vehicle.
• Part of flight simulation test for GRO satellite, involving extensive hardware-in-the-loop testing and flight software debugging.
• Wrote numerous simulations for orbiting spacecraft, interplanetary exploration vehicles, missiles, and sounding rockets.

• Ran several radiation and particle transport codes to analyze radiation damage in spacecraft and missile silos.
• Performed small analysis tasks in various disciplines (orbital mechanics, radiation transport, acoustic wave propagation).

• Performed analytical and computational research in RF current drive in tokamak fusion reactors.

• Developed software for satellite data processing in support of National Oceanographic and Atmospheric Administration atmospheric ozone study.

• Modified and improved an optical systems design program for NASA Goddard Space Flight Center.
