PAST WORK EXPERIENCE

• Researched, developed, and implemented audio fingerprinting algorithms for the identification and classification of digital music. Worked on the concept, design, MATLAB prototype, and C++ implementation of the algorithm as part of the R&D group.
• As Technical lead of the R&D group during development of the second generation of the audio fingerprinting algorithm, fostered the adoption of solid software construction, testing, and documentation procedures within a fast-paced research environment.

The audio fingerprinting technology was acquired in 2001 by Gracenote/Sony, the leader in digital music identification, and is now incoporated into the Gracenote MusicID™ product. The technology is being used by Apple iTunes and Yahoo Music, among others. A patent has been issued: "Automatic Identification of Sound Recordings," USPTO N. 7328153.

• Researched, developed, tested specialized algorithms for applications in digital signal processing, including adaptive filtering, blind equalization, wavelets and time-frequency analysis, image processing, tactical communications, image texture analysis. Contributed to the development of specialized software modules for the scientific computing language S-PLUS.
• One of the key developers of new versions of the digital signal processing and image processing toolboxes for Mathcad, a leading technical visualization and scientific computing software package.

• Contributed to development and improvement of real-time pattern recognition system for cloning fraud detection in cellular communications.
• Applied numerical algorithms to RF fingerprinting, statistical analysis, fuzzy logic, and neural networks.

• Modeled semiconductor manufacturing processes. Applied artificial neural networks to function approximation, interpolation, parameter extraction, and optimization.
• Designed, implemented, and maintained web site. Wrote CGI scripts in Perl for automated web-based resume and homepage creation. The web pages describing the facilities are still being used to give visitors a virtual tour of the Center.
