Research Interests: I design systems using a circuits perspective. While at Berkeley, I've focused on microelectromechanical systems and interface circuits for them.
Job Interests: Full time (in 2014): Academic or industry R&D - MEMS & chip design

Richard Przybyla received his PhD in Electrical Engineering in Prof. Bernhard Boser's research group at UC Berkeley. During his research he demonstrated a low-power, mobile-friendly ultrasonic gesture recognition system which fits on a chip. The technology is being commercialized by Chirp Microsystems in Berkeley, which he co-founded. Richard has held R&D positions at Hewlett-Packard and Oregon State University, where he received his BSEE in 2008. In 2012 he was a finalist for the TSMC Outstanding Student Research Award. Richard is interested in circuits and systems which interface to the physical world.

Ultrasonic Gesture Recognition on a Chip [BPN485]
Optical 3D imagers for gesture recognition, such as Microsoft Kinect, suffer from large size and high power consumption. Their performance depends on ambient illumination and they generally cannot operate in sunlight. These factors have prevented widespread adoption of gesture interfaces in energy- and volume-limited environments such as tablets and smartphones. Gesture recognition using sound is an attractive candidate to overcome these difficulties because of the potential for chip-scale solution size, low power consumption, and ambient light insensitivity. Our research focuses on building an ultrasonic depth sensor system using batch-fabricated micromachined aluminum nitride (AlN) ultrasonic transducer arrays and custom CMOS electronics.
