• Designed Raspberry PI HATs (Hardware Attached on Top) for automated testing of proprietary ICs; oversaw all workflows from initial conception to final design, including creating a power budget, selecting parts.
• Interfaced with the firmware design team in debugging I2C and SPI communication protocol issues and implementing adjustable voltage rails and power measurement capabilities in the existing communication HAT
• Identified a startup software issue with the HAT, which enabled the team to produce working communication HATs that could be shipped to customers and other teams globally for automated testing of touch ICs
• Improved portability of existing test systems by creating PCBs separated into functional blocks— reduced time spent in the design process for future HATs

• Programmed, tested, & released a test rack for the qualification of an aerospace client’s custom valve driver board; implemented a multithreaded program to control multiple test rack relay boards
• Performed Monte Carlo worst-case circuit analysis in LTSpice and probed signals on a linear actuator/motor driver PCB to debug customer hardware
• Designed system requirements, power budget, and component layout for a thin form factor tracking device; created the layout for a mechanical sample on a 2-layer rigid-flex PCB in Altium Designer and coordinated with a.
• Modified thermal chamber hardware and wrote Python code to automate testing for various qualification programs, which reduced desync errors between temperature and tests being run
• Performed a transmission delay line experiment to characterize the behavior of a novel energy storage device

Created a robotic stage arm and programmed an Arduino to take precise measurements of a 3D magnetic field gradient for applications in intramedullary nailing surgeries. Also programmed an interpolation and search algorithm in MATLAB for 1:1 mapping of coordinates to magnetic field magnitudes. Second author on a related paper submitted to ISSCC.
