About me

Early Beginnings

I became fascinated by engineering research in my early teens. At the time, I put together a magnetic propulsion experiment using a piece of Styrofoam that I found on the beach and wire from an old transformer. As I plugged my device into the wall electrical outlet, my engineering career began with a spark!!

Education

I am a Big Ten fan having attended Northwestern University (NU) in Chicago and Penn State University (PSU). Although, I attended NU for the first two years of my PhD, our entire team transferred to Cedars-Sinai Medical Center (Cedars) in Hollywood, CA., and I completed my degree at the University of California, Los Angeles (UCLA). While at Cedars, I conducted my graduate research in Magnetic Resonance Imaging (MRI) for breast & prostate cancer imaging at the molecular level, with focus in hardware and software development. I received my master's in Electrical Engineering (EE) at PSU, with focus in electronic and piezoelectric material linear motors (PZT motors). I obtained a Code Division Multiple Access (CDMA) Engineering Certificate from the University of California, San Diego (UCSD), the most fun course work I ever had in Radio Frequency (RF) Communications. I obtained my bachelor's in EE at San Diego State University (SDSU) with a focus in electronic circuit applications in electrophysiology and finger force measurements.

Engineering

My first job as a teenager was working at Electromar as an electronic technician. I started out sweeping the shop, then moved on to programming in Basic and repairing Echo Sounders, Sonars, and Radars. It was the greatest job for a eager to learn engineering teenager like myself. My next jobs were with Helle Engineering, Ectron Corp, Air Force Space Surveillance System, (AFSSS) San Diego station (contractor), Cadence Designs Systems (Cadence), and Testedge inc (TE). As a technician at Helle Engineering, I learned to build and repair piezoelectric pingers for underwater detection and communication. Then, at Ectron, I became experienced in diagnosing, troubleshooting, and calibrating electronic circuits in Thermocouple simulators/calibrators. I also became skilled in Data Collection and Automation using HP Basic and GPIB. In my next position at the AFSSS, I learned the ins and outs of large scale remote sensing and satellite detection. I also began producing quality circuit designs, C/C++, and LabView software programs. Later, as a senior engineer at Cadence and Testedge, I became adept at Test Engineering with mixed signal circuit designs, high speed data collection, automation, and C/C++ programming.

Today

Currently, I am a product development engineer at Intel and hold 5 patents and 12 publications in hardware and software with a biomedical devices focus. In my spare time, I volunteer for Pot Luck in The Park feeding the homeless and serve at the board of directors for the Community Partners for Affordable Housing (CPAH), a non-profit organization providing affordable housing for low income families and individuals in the Portland metro area.
