Professional Summary
Security-focused computer engineer with an active Top-Secret clearance and a Ph.D. in Computer Engineering from Virginia Tech. Research interests span software and systems security, control-flow integrity, secure system design, compiler- and binary-level security, ARM architectures, and software supply-chain verification.
Experience
-
2025 - Present McLean, VA
Senior Cyber Engineer
MITRE Corporation
Building automated tooling for software supply-chain verification, secure system architecture analysis, and Multi-Level Security prototyping.
- Developed a modular, containerized framework for automated software supply-chain verification, extending TruffleHog to improve secret-scanning and dependency-analysis coverage across source repositories.
- Authored technical documentation and conducted architectural analyses of processor (RISC/CISC) and system design trade-offs to support modernization and performance optimization decisions.
- Led the design and deployment of an automated, non-source-artifact assessment pipeline that enables stakeholders to assess contractor proficiency without requiring proprietary source code.
- Co-led the architectural design and rapid prototyping of containerized Multi-Level Security (MLS) environments. Developed MVPs to validate robust data protection, labeling challenges, and cross-classification data sharing, directly informing trade-space evaluations for critical federated systems.
- Directed automated Infrastructure-as-Code (IaC) analysis workflows and engineered headless system modeling templates (e.g., Cameo), enabling the programmatic extraction of architectural insights from high-level artifacts to conduct predictive risk assessments.

2018 - 2024 Blacksburg, VA
Research Assistant
Virginia Tech
Ph.D. research with Dr. Binoy Ravindran on compiler- and binary-level security: control-flow integrity, ARM Memory Tagging Extension integration, and automated data compartmentalization.
- Designed and deployed compiler- and binary-level security mechanisms to enforce control-flow integrity and automated data compartmentalization across untrusted code modules.
- Integrated the ARM Memory Tagging Extension (MTE) into a compiler toolchain, strengthening runtime memory safety and fault isolation.
- Implemented static and dynamic taint analysis to identify sensitive data paths and compartmentalization targets, automatically rewriting assembly code to isolate protected data regions.
