Mark studied computer science and information security and did his PhD on usable and secure computing. He worked as software, security, and privacy engineer over the past decade, his current position being Mgr. of AppSec at LogMeIn. Since his research in user centered computing, he has been arguing that human behavior, beliefs, and motivations cannot be excluded from the design of any solution being designed for actual users. This includes technical solutions that wish to solve for these aspects, as well as methods to foster the communication during the design process. This is true for software systems, security solutions, or privacy programs as well.
