About

This blog is solely related to my academic research and teaching portfolio. In addition to this site, I also maintain the Information Security Leadership Blog and The Technology Toolshed.

My main research interest revolves around defensive cybersecurity, with a focus on cyber threat analysis. My research is grounded in access control theory, information security management and conceptual modeling.

I am currently affiliated with the Department of Mathematics and Computer Science at Adelphi University as an associate professor. In that role, I act as chair of the department. I also have a secondary appointment in the Office of Information Technology as the university’s Information Security Officer/CISO.

By popular demand: my name is Dutch in origin and is pronounced as “Case Loehne”. My last name is notoriously difficult to pronounce for native English speakers. For your convenience, I also have a recording.
