Summary
Designing electronics that operate in harsh remote environments above and below the ocean’s surface. Skilled in circuit design, PCB layout, prototype and limited-run electronics fabrication, system integration, and field deployment of hardware in demanding conditions.
Experience
University of Washington – Applied Physics Laboratory
Senior Hardware Design Engineer · 2022 – Present
Below details some of my larger projects:
MicroSwift Buoys
- Aircraft deployable buoys that measure ocean surface dynamics, specifically wave motion
- Primary study is Arctic Sea Ice formation/melting and Hurricane wind/wave interactions
- Highly manufacturable
- Multi-PCB modular design leveraging manufacturing to minimize labor
- Design-For-Manufacturing (DFM) achieves high first pass yield (Above 90%)
- More than 100 deployed (Beaufort Sea, Chukchi Sea, Gulf of Mexico, Atlantic Ocean)
Medium Voltage Node Controller (Seabed Node)
- Designed a 375V DC 1.5kW custom short-circuit protected load switch
- Isolated high-side analog feedback controlled
- Detects, controls, removes short circuit within 7 microseconds to maintain semiconductor safe operating area limits
- System design (Custom & COTS) for a Linux-based controller assembly
Buoy Controller for Northwest Environmental Moorings
- Low-Power Linux-based controller
- Protected power & serial/Ethernet to downstream science equipment
- Designed a built-in USB2.0 High-Speed (480Mbps) hub to provide the computer with a large number of full-bandwidth capable RS-232 and RS-422
- Designed for easy manufacturing and low-harnessing needs
3kWh Lithium-Polymer Submersible Smart Battery
- Designed, tested, and deployed a pressure-balanced (oil filled) submersible battery pack
- COTS battery management system (BMS) modified for 300m deployment capability
