Accepted to the Ph.D. Program at UNM!
Published:
I’m excited to share that I’ve been accepted into the Ph.D. program in Computer Science at the University of New Mexico.
IEEE Aerospace Conference Trip
Published:
Had an awesome time at the IEEE Aerospace Conference in Montana.
Silent Subversion Completed!
Published:
The second major milestone in my small-satellite cybersecurity work is complete — Silent Subversion, now submitted to the 2026 IEEE Aerospace Conference.
This project builds directly on SpyChain but focuses on an even subtler problem: when a satellite’s own sensors can no longer be trusted.
Finished SpyChain!
Published:
After nearly a year of design, implementation, and refinement, the SpyChain project is complete.
SpyChain represents the first full simulation of coordinated, multi-component supply-chain malware within a small-satellite environment, implemented entirely inside NASA’s NOS3 framework.
Graduated from UNM with a B.S. in Computer Science!
Published:
I’m proud to share that I’ve officially graduated from the University of New Mexico with a Bachelor of Science in Computer Science.
Accepted to the M.S. Program at UNM!
Published:
I’m thrilled to share that I’ve been accepted into the Master of Science in Computer Science program at the University of New Mexico.

Securing U.S. Critical Infrastructure: Lessons from Stuxnet and the Ukraine Power Grid Attacks
Published in arXiv preprint, 2024
Analyzes the and incidents to reveal persistent vulnerabilities in U.S. critical infrastructure and proposes zero-trust and network segmentation strategies to improve resilience against future cyber threats.
Power Grid Cybersecurity: Policy Analysis White Paper
Published in arXiv preprint, 2024
Identifies systemic cybersecurity weaknesses in the U.S. power grid and proposes a dual strategy of enhanced information sharing and standardized cyber hygiene, alongside a unified national framework and standards to strengthen long-term resilience.
Silent Subversion: Sensor Spoofing Attacks via Supply Chain Implants in Satellite Systems
Published in AeroConf 2026 IEEE Aerospace Conference, 2025
Presents a NOS3-based simulation of supply chain–implanted malware, where a compromised satellite generates falsified telemetry that appears legitimate to ground control while retaining the ability to disable the targeted device.
SpyChain: Multi-Vector Supply Chain Attacks on Small Satellite Systems
Published in arXiv preprint, 2025
Demonstrates the first end-to-end simulation of multi-vector supply chain malware in NASA’s NOS3 environment, revealing how colluding satellite components can exfiltrate data and evade detection.
