Senior cybersecurity and emerging technology leader pairing executive leadership, national policy authorship, and hands-on technical practice across 15+ years at the White House, New York City Cyber Command, Memorial Sloan Kettering Cancer Center, and financial services. Lead author of OMB M-26-14 on federal logging and network visibility and OMB M-26-15 on the migration to post-quantum cryptography, with a technical foundation of 275+ penetration tests and 550+ risk assessments. Technology is the great equalizer, and security must protect and enable the mission.
I am a senior cybersecurity and emerging technology leader who pairs executive leadership and national policy authorship with deep, hands-on technical practice. Over 15 years I have worked across the White House, New York City Cyber Command, Memorial Sloan Kettering Cancer Center, and financial services.
I began my career penetration testing, leading red team engagements, and working in a SOC, learning the vulnerability lifecycle firsthand from discovery through remediation. Over time I expanded into building enterprise security programs, coordinating vulnerability disclosure, designing evaluation and risk frameworks, modernizing detection strategies, and shaping national cybersecurity and emerging technology policy. Being both highly technical and experienced at advising executives, I translate complex technical risk into clear, principled decisions for leaders and stakeholders.
Today I lead technical cyber and emerging technology portfolios at the White House, in the Office of the Federal Chief Information Officer at the Office of Management and Budget. I am the lead author of OMB M-26-14, which modernized federal logging and network visibility to enable AI driven detection and automated defense, and OMB M-26-15, which directs the federal migration to post-quantum cryptography, and I serve as a federal Major Incident Response Commander.
Before policy, I built a technical foundation of 275+ penetration tests and 550+ risk assessments, ran audit and compliance programs across HIPAA, PCI DSS, SOX, FedRAMP, SOC 2, and ISO 27001, and helped build continuous audit at citywide scale. I hold dual bachelor's degrees in Computer Science and Experimental Cinema and Production from Binghamton University, and I try to bring that design sensibility to everything I make.
Technology is the great equalizer.
Security must protect people, institutions, and infrastructure from harm while enabling innovation, mission objectives, and forward progress.
When security becomes overly restrictive, it slows the work it is meant to safeguard. When security is careless, it introduces unacceptable risk or enables misuse by those who would exploit humanity's new tools. The responsibility of successful cybersecurity is to design systems and policies that achieve both.
Unmanaged or left vulnerable to abuse, technology amplifies harm and inequity. Designed responsibly, it is the great equalizer.
That belief has shaped a career in public service at the White House, in New York City government, at the United Nations, and in nonprofit healthcare, intentionally built around ensuring that technological advancement protects and enables the mission of organizations that serve people and the greater good.
Let's talk.
Open to conversations on cyber policy, AI security, post-quantum migration, and building programs that earn trust.
