Distinguished Incident Response Engineer at Walmart Global Tech

Senior applied security researcher within Walmart's Information Security organization. My work spans novel threat detection, machine learning–based defense, and advancing LLM and agentic AI tooling for enterprise security. I hold two production-deployed security patents and lead an active R&D research team.

I'm an HCI researcher turned security practitioner with a deep interest in how people and systems interact with security technology. My PhD research at Michigan State focused on blockchain adoption, and my practitioner work has taken me from phishing behavior at scale to kernel-level LLM agent containment using eBPF.

During my PhD I interned with Walmart's InfoSec division and at a federally funded R&D center at MIT Lincoln Laboratory. My academic advisors were Dr. Stephanie Jordan and Dr. Johannes M. Bauer. I was also a member of the BIT Lab run by Dr. Rick Wash.

Current Focus Areas

  • LLM & Agentic AI Security
    • eBPF-Based LLM Agent Containment
    • AI-Assisted SOC Automation
    • LLM Risk & Exposure Analysis
  • Applied Research
    • Phishing Behavior at Scale (NIST)
    • Mixed-Methods Security Studies
    • Enterprise Security Tooling

From Software Engineering to Security Research

"Good software, like wine, takes time" — Joel Spolsky

Coding at work

I started out believing that writing software would be one of the coolest jobs in the world. I still love to code — but industry taught me that what I really enjoyed was leveraging data into insight. That pull toward analysis drove me back to academia, and eventually toward security research as the richest intersection of both.

Over graduate school and my time at Walmart, I've applied ML to threat hunting, built KQL detection pipelines on Azure Sentinel, developed agentic AI tooling, and explored kernel-level security primitives using eBPF. I've published at NDSS, USENIX SOUPS, and WOSOC, and hold two production-approved security patents. The goal has always been the same: solve real problems with code.
