Selected for a competitive national security cohort; engaged 15+ senior officials across the Pentagon, Capitol Hill, and CNAS.

Directed discussions on GPS-denied navigation, resilient communications, and electronic warfare threats for non-technical audiences.

Identified research pathways for ARMS aligned with areas discussed by USSOCOM, USCENTCOM, and major defense contractors.

Fabricate tactical communications wiring harnesses and aerospace cable assemblies in compliance with IPC-A-610 Class 3 standards.

Crimp multi-pin circular connectors and perform high-reliability cup soldering for board-level electronic assemblies.

Isolate wiring, routing, and insulation faults via point-to-point continuity and resistance testing with digital multimeters.

Map EMI shielding, backshell strain reliefs, and lacing by interpreting physical nailboard layouts, assembly drawings, and wire run lists.

Developing a GPS-denied navigation prototype using C++/MATLAB Kalman filtering to fuse simulated 6-DOF IMU and atmospheric data.

Error Characterization: Conducting Inertial Dead Reckoning studies to establish sensor bias baselines and reduce cumulative drift.

TT&C Implementation: Building a Telemetry, Tracking, and Command ground station for real-time state estimation and fault monitoring.

Hardware Design: Engineered an ESP32-based power distribution unit to monitor real-time loads with a ±0.5% current sensing accuracy.

Control Logic: Developed PWM-based trip-logic to prevent overcurrent, maintaining system stability within 10% of peak rated capacity.

Bench Testing: Utilized digital oscilloscopes to validate signal integrity, reducing noise (Vpp) by 35% through active RC signal conditioning.

Conducted load-flow simulations in MATLAB to identify service recovery strategies, optimizing simulated grid restoration time by 22%.

Built an AI-driven simulation model to analyze failure propagation across 7 infrastructure layers, generating 500+ unique grid outage scenarios.
