Researcher and Engineering Leader in Security, Privacy & Generative AI
I am a Researcher and Engineering Leader in Security, Privacy & Generative AI at Cisco's Security Business Group (SBG). My work focuses on understanding and mitigating risks in modern AI systems, particularly Large Language Models (LLMs), and developing context-aware security frameworks for mobile and IoT platforms.
In this role, I lead a talented team focused on the Secure Firewall Management Center. Our work centers on building core platform components like Authentication, Authorization, and Auditing (AAA), REST API frameworks, and cloud service integrations. I am deeply committed to driving security-focused development and have led several key initiatives around SAML SSO, external authentication, and software compliance standardization.
A core part of my role is leading the engineering response to complex, critical vulnerabilities. For example, for the Blast-RADIUS (CVE-2024-3596) CVE, my team was instrumental in the triage and effective remediation efforts across Cisco. This experience demonstrates my proficiency in managing high-stakes situations, combining deep technical knowledge with a strategic, collaborative approach to crisis management.
With over 18 years of combined experience across industry and academia, I bring a unique perspective to software development—grounded in deep technical knowledge and a passion for security and scalable systems. My expertise includes developing solutions for Single Sign-On (SSO) and Multi-Factor Authentication (MFA), and deploying technologies using modern infrastructure like Docker and Kubernetes. My Ph.D. in Computer Science from the University of Maryland, Baltimore County, and internships at Apple, Samsung, and Symantec have uniquely prepared me to build secure, reliable, and user-centric systems.
Today, I am interested in Senior Leadership positions where I can drive delivery across multiple teams, influence architectural direction, and mentor the next generation of engineering talent. While cybersecurity is my core domain, I am always open to exploring new problem spaces where I can bring value through thoughtful leadership, technical vision, and a commitment to building and delivering high-quality software.
