Biography

I graduated from the University of Pennsylvania, received a B.S. in Electrical and Electronic Engineering. After graduation, I worked for eight years at Denton Vacuum Inc. as a chief engineer in system integration and automation. I have designed systems for Los Alamos National Lab, Oakley, Pentax, Ford, etc.

Prior to joining Janelia, I worked as an entrepreneur in pursuing more challenging projects. I have provided services and designs for numerous customers such as Merck Pharmaceuticals, U.S. Army, Ford Motor, Day & Zimmermann, etc.

My engineering expertise are:

  • System Integration and Automation
  • Analog/digital mixed-signal design,
  • High-speed digital circuits
  • FPGA/micro-controller based embedded electronic systems,
  • High-speed digital camera design,
  • Various Communication protocols: Bluetooth LE 5.0 and PCIe3.0x8
  • High density and complex print circuit board design
  • Camera and camera systems from 200nm to 16um spectrum
  • Photon counting for quantum password
  • Focal Plane Array laser diode (1.5um-1.6um) camera
  • Plasma-enhanced chemical vapor deposition
  • Standard communication protocols, I2C, RS232, RS484 and SPIE
  • Mechanical design using Autodesk Inventor
  • FPGA VHDL/Verilog programming,
  • Microsoft Visual C/C++ programming,
  • Micro-controller based
