About

Senior Security Researcher at Microsoft Threat Intelligence (MSTIC) on the MSTIC‑MIRAGE team, specializing in malware reverse engineering and threat intelligence to track, analyze, and disrupt nation-state sponsored advanced persistent threats (APTs). I convert deep technical analysis into customer‑protecting detections and clear, actionable intelligence, partnering across engineering and threat intel teams to strengthen Microsoft’s defenses at global scale. I contribute to internal briefs and technical publications, mentor peers on reverse engineering workflows and tooling, and drive automation to speed high‑quality detections. Passionate about proactive threat hunting and continuous learning, I focus on outcomes that raise defender resilience and reduce real‑world risk. Previously, I built a strong DFIR foundation through incident response roles at Amazon Web Services (AWS SecOps) and LinkedIn (SEEK), and I also hold an MS in Secure Computing from Indiana University, Bloomington.

Graduate Assistant

Jan 2017 – May 2018 · 1 yr 4 mos · Bloomington, Indiana Area

Developed a Mini-ScienceDMZ (Mini-DMZ) as part of a NSF funded project.
My responsibilities included developing a Mini-DMZ which would include a firewall, data transfer node, performance management, and the ability to digitally sign data as it first enters the workflow.
Instruments such as electron microscopes, DNA sequencers, MRIs, and crystallography microscopes
have unique security challenges. These instruments are paired with Windows-based PCs that
serve as their controller and data transfer platform. The instrument and the controller are
purchased and maintained as a single integrated unit. The PC is required to run a specified
operating system, which may be unpatched, or even be obsolete (e.g., Windows XP). The Windows-based controller uses local or remote file systems, typically based on Samba, as its method for
storing and exchanging data. This leaves the instruments and their data highly vulnerable
to unauthorized manipulation via well-known network-based attacks.
The goal of the project is to provide security to such devices.
