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.
  • 2017 - 2018

    State College, PA

    Software Engineer
    Raytheon
    Documentation compliance for unclassified deliverables while clearance was processing.
    • Supported documentation compliance for unclassified deliverables pending clearance activation.
  • 2017 - 2017
