Jan 2011 – Aug 2013 · 2 yrs 7 mos · Self Employed Consultant

• Both Project Lead and Systems Engineer for an X-Band (radar) sniper bullet detection system.
• This system required handling of 140 dB dynamic range with negative SNR far-range signals.
• Responsibilities include: baseband circuit design, timing, synchronous demodulation, filtering
• design trades and optimal implementation of analyses.
• Engineer/Scientist and Systems Architect for a high bandwidth, very low noise Optical Coherence
• Tomography (OCT) tunable medical laser. Development of very high bandwidth 200 mA nonlinear
• laser drivers. Detection circuitry processes received light with a 1 GHz , 80 dB SNR. Additionally,
• responsible for repackaging from a desktop product to a ½ shoebox-sized volume.
• My consulting work centers largely around design and deployment of high to very-high performance signal processing solutions. i.e. High bandwidth, low to very-low noise circuit solutions in either the time or frequency domains (or both). I work best with interdisciplinary challenging projects where trades must be performed to determine which domain (hardware, firmware, software) is best suited for a processing task.

Mar 2004 – May 2009 · 5 yrs 2 mos · Boulder, Colorado

• Supervised a team of Box Responsible Engineers for the design, debug, construction and testing of analog spacecraft hardware.
• Responsible for all comm. subsystems, box designs for WorldView I, WorldView II, and JPSS (formerly NPOESS Preparatory Project, or NPP) Spacecrafts. Prime projects included a mission-critical ultra low-noise 2-axis Gimbal System for Uplink/Downlink R.F. communications. Also worked at a systems and circuit level with X band phase-modulated transceiver systems for spacecraft comm. Served as a consultant both within and outside of Ball for seemingly intractable technical and logistical problems.
• Responsible for the introduction, evolution, implementation and testing of 2.4 GHz position location systems using time-frequency based differential time-of-arrival algorithms. Developed embedded real-time multi-DSP code and ported between Matlab, Code Composer (TI54xx, JTAG Target), and Borland 5.02. Implemented sophisticated embedded real-time algorithms.
