Studied privileged insider cryptocurrency mining and authored a whitepaper on shadow mining. Researched multiple problem domains for expanding detection capabilities including Industrial Control Systems (ICS) and container and container orchestration attacks. Gathered customer data and authored measurement studies to identify and predict trends. Co-developed Zoom detection capabilities (in Python) as pandemic-driven remote work emerged. Co-developed an agnostic mechanism to identify attempts to extract windows credentials from memory and identify LSASS attacks. Built Exabeam’s automated detection lab for gathering various telemetry and developing new detection content.As technical lead of the research team mentored other researchers helping them approach research into electronic health records and financial systems. Also mentored many detection content developers and customer success team members through an informal program that led to authoring a formal detection triage program. As a thought leader helped shape the research roadmap, provided security expertise to Exabeam's data science, marketing, and PR teams and gave media interviews. Received the most valuable Exabeamer award for Q1 2020.
