Type of Position Sought: Senior systems architect/designer or technical team leader, offering opportunity to interact with and motivate team members and to demonstrate use of structured processes in design and implementation.

Areas of Expertise:

· Digital Signal Processing - development and low-level code and logic implementation of algorithms for speech recognition, image analysis; innovative approaches.

· Software Development - over 10 years in C under Linux, UNIX and Windows; knowledge of UNIX networking internals (socket interface); have used Visual C++, Visual Basic, Matlab, also Python and Java under Linux; developed Linux kernel modules; PHP and MySQL for Web-based applications.

· Data Acquisition and Analysis - real-time measurement and event capture in industrial, neuromedical (spike sorting) and communication environments.

· Training, Instruction, Documentation - excellent presentation and communication skills; 15 years university teaching experience.


Recent Professional History:

CONTRACT CONSULTING & ACADEMIC TEACHING 2001-present

a) Plexon, Inc., Dallas, TX (Sep. 2005 to present) - Contract researcher, working at company supplying electronic instrumentation to biomedical laboratories for neuroelectric research. Using digital signal-processing expertise, developed algorithms for real-time separation of "spike" activity of multiple nerve cells in brain tissue recorded on single electrode channel (presently-used techniques generally require exhaustive off-line processing), as extension of own Ph.D. work. Implemented algorithms in Matlab for demonstration purposes, using recordings of actual data; results compared favorably with those for off-line methods.

b) Minco Technology Labs, Austin, TX (June 2004 to Aug. 2005) - Contract consultant to custom semiconductor packaging house. Proposed project to consolidate data in various separate databases, making information accessible to improve accuracy of job pricing and scheduling estimates. This initiative led to a decision to migrate internal operational IT from a legacy mainframe to a custom Web-based application platform using LAMP (Linux, Apache, MySQL, PHP) open-source tools. Wrote initial PHP module, for generating and sending sales quotes as HTML email, deployed in spring of 2005 with highly favorable response from sales staff as well as from customers.

c) University of Texas - courses taught (as adjunct lecturer)
Fall 2001: Logic Design Using VHDL (senior EE), at Austin campus
Spring 2003: Pre-calculus (1st year), at Permian Basin campus (Odessa, TX)


NETHEARTBEAT, INC., Austin, TX 2000-2001
Senior Systems Architect, functioning as technical team lead
Design, implementation and development, in small startup company environment, of load-balancing solution for clusters of Web servers under Linux. Took responsibility for major system components coded in Java, also Linux kernel modules in C. Advocated systematic design procedures including writing of functional descriptions and formal design specifications. Led technical discussions to resolve design issues.


ANDREW CORPORATION, Austin, TX 1999-2000
Senior Engineer
Implementation and development of digital signal processing algorithms for cellular telephones and accessories, as member of small R&D facility doing advanced product development. Tools used include: Matlab with Simulink; Analog Devices ADSP-2181 DSP processor and associated development environment. Investigated solutions for implementing voice dialing, robust echo suppression for speakerphone adapter, etc.


SYMTX, INC., Austin, TX 1993-1999
Systems Architect
Design and implementation of custom systems in project-driven small-company environment, using primarily Hewlett-Packard components (company is an H-P Channel Partner). Developed modular software (mainly in C) under MS-Windows and UNIX for system processors driving digital instrumentation in real time. Dealt directly with clients; advised on approaches to meet special requirements. Performed project-management functions; worked independently and as head of small teams (typically 4-5 junior engineers). Served as design leader on several projects including:
· Design and development of cable-modem testers, beginning with analysis of test requirements, design and lab-bench verification of test algorithms, software implementation of tests, and checkout using production prototypes.
· Generator of simulated deep-space telemetry signals to monitor receiver performance (bit error rate vs. SNR, etc.) for space-probe downlink. Complex modulation patterns digitally calculated and downloaded to real-time microwave synthesizer.
· Airborne data acquisition system involving merging of multiple avionics data streams at different rates, for modeling aircraft dynamic characteristics for design of flight simulators. Instrumentation consisted of VXI-interface modules controlled by C code running on real-time UNIX computer, with operator control via C++ application running on Windows laptop PC connected in client-server mode via Ethernet socket interface.


THE MITRE CORPORATION, Bedford, MA 1984-1992
Member of Technical Staff
Applied innovative digital signal processing approaches to speech and images. Proposed a novel spectral representation inspired by knowledge of neural encoding of sound in the ear. Implemented a computational model for wave transmission in the cochlea (inner ear) using the wave-digital-filter technique, to investigate possible effects of active nonlinearity in the ear (as evidenced by recent research in auditory physiology) in enhancing speech intelligibility in noise.


Education:
