Design Engineer, February 2009 to October 2014Schematic capture and PCB layout for main circuit board for AntennAlign and sun sensor products. Schematic capture and PCB layout for other misc. I/O boards.

Designed a VME Digital Drop Receiver (DDR) board consisting of ten 12-bit A/D channels sampling at up to 60MHz and multiply-accumulate digital filters with programmable filter coefficients, magnitude comparators for trigger generation, FIFO storage for data samples, and an FPDP transmitter. Designed various mezzanine boards for the General Purpose I/O (GPIO) VME board including the FRADC-8-10242 (an eight channel, 12-bit, 60MHz A/D board), the FRADC-2-10242 (a two channel, 12-bit, 60MHz A/D board), the FRDA-4-14100 (a four channel, 14-bit, 100MHz D/A board), and the FRDIO/SE and FRDIO/D (32-bit single and differential ended 400MB/s digital I/O boards). Co-designed the FPDP-PMC, a PMC board that provides a 160MB/s parallel I/O interface. Created PCB layout of all of the above products using Tango PCB layout software and Orcad schematics capture.

Design engineer on Air Force Minuteman MK12/12A Reentry System Test System (RSTS). Coordinated PEI designs with overall RSTS system design taking into account customer requirements and Commercial Off-The-Shelf (COTS) capabilities. Assisted with completion of preliminary RSTS system design. Completed preliminary design of RSTS timer board for the VXI bus.

Served as design engineer for NASA, Marshall Space Flight Center (MSFC), Earth Science and Applications Division (ESAD) in the ES43 branch. Developed data acquisition and remote sensing equipment and software for the lightning research group. Developed Ground-Based Optical Sensor System (GBOSS) consisting of optical pulse sensors, and all-sky lightning detector, electric field meters, and other electric field measuring devices. Designed a camera simulator for the space-based Lightning Imaging Sensor (LIS). Completed preliminary design of a solar-powered embedded PC data acquisition system with integrated GPS receiver and LCD display. Designed the Lightning Instrument Package (LIP) consisting of atmospheric conductivity probe, electric field meters, and data acquisition system. Coordinated integration of the LIP onto NASA’s ER2 aircraft and provided engineering support and data analysis for LIP during thunderstorm missions off the eastern coast of Australia. Developed the Advanced Ground-Based Field Mill (AGBFM) Test & Calibration Facility consisting of computer controlled test equipment and data acquisition software. Wrote extensive test software used by NASA Kennedy Space Center (KSC) to validate operation of around 40 field mills presently in use for lightning prediction and range safety for all shuttle and military launches. Trained KSC personnel on the use of the test and calibration software. Wrote base-station software to capture and display data from, and to control two AGBFMs from a standard PC. Wrote AGBFM simulator software.
