Message

At the United States Air Force, I lead defensive cyber operations as Branch Chief, Defensive Cyber Operations at USCENTCOM. I focus on protecting critical systems through mission prioritization, threat detection, risk mitigation, and incident response.

I’ve strengthened cybersecurity partnerships with 20 international organizations and coordinated distributed teams to identify, contain, and eliminate malicious activity. I also deliver threat intelligence and operational updates to senior leaders to support decisions about risk and mission priorities.

Earlier, as Flight Commander Joint Cyber Training, I led cybersecurity training programs and helped modernize training infrastructure with a cloud-based environment that reduced student downtime by 99% and saved $60K in travel costs. I bring experience across cyber operations, incident response, network defense, and workforce training, backed by certifications including CISSP, GIAC, CompTIA, and CEH.
