Work

Featured projects

Parallel Quantum Frequency Processor

Developed a modeled a multi-frequency, parallel photonic signal processing architecture for high-dimensional quantum and classical communication systems. Simulating a parallel MZI array for frequency-domain modulation, enabling controlled transfer matrices across RF carriers.

Python MATLAB DSP / FFT

Bio-inspired Antenna Sensor for Shrimp Autonomous Underwater Vehicle

A resin-printed antenna modeled after a seal vibrissae seeking to identify external vortex disturbances in the surrounding environment, while reducing vortex-induced vibrations and minimizing natural frequency disturbances.

Arduino Modal Analysis Circuit Design

Vibration Isolation Mechanism

Designed an aluminum structure to minimize transmissibility between vibrating base and payload across 8-45Hz, achieving ~95% reduction in transmissibility across target frequency range.

Dynamics CAD MATLAB

About

Hey y’all, I’m Murphy. I’m a mechanical engineering student at Brown with an electromechanical focus, drawn to the challenge of applying math and physics to solve problems across scales, from dynamic structures to micron-level photonics. I thrive on competition, precision, and collaboration, shaped by my experience as a Division I athlete. Every project is a chance to break down complexity, test ideas under real constraints, and deliver solutions that work. In a world where technology and global priorities are evolving at record speed, I’m committed to bridging the gap between possibility and execution by designing, building, and optimizing systems that make an impact.
