Research Statement

My research follows two main threads: The first explores the technical, organizational, and human/social challenges of information and industrial control systems. This work leads to the development of tools and strategies that apply more broadly to the security of networked cyber-physical and information technology systems. The second investigates educational and training delivery solutions and content that results in a diverse pool of talent with the skills needed to protect organizations and improve critical infrastructure.
