Research. I strive to envision what the world might be like the next 5, 10, or 15 years, anticipate what risks and harms might arise (under various possible futures), and then proactively and ethically study those risks+harms and explore mitigations. I am particularly interested in (1) exploring new, previously unexplored technologies and research areas, (2) exploring existing research areas with novel, new approaches, (3) exploring issues of contemporary importance, (4) conducting work that is cross-disciplinary, (5) leveraging the best methodologies to explore the questions at hand (e.g., user studies, Internet crawlers, or experimental attack explorations), and (6) conducting work that is import to society and that recognizes that society and technology are deeply intertwined.

Example technology areas of study include:

Example themes that crosscut my research include:

Education. I care deeply about education, including helping students understand the importance of understanding and carefully considering the relationship between society and technology.

  • Early in my teaching career, I introduced "security reviews" and "current events" assignments into my undergraduate computer security courses. My goal was to help students learn to think broadly about technology and the relationship between society and technology. Wired provides a summary of my course’s use of "security reviews". I modeled the "current events" assignment off an assignment from my high school history course.
  • In 2012, my colleagues and I released a card game called Control-Alt-Hack, the goal of which was to help raise awareness about key computer security concepts, as well as the breadth of technologies that could be impacted by poor computer security design choices and the human impacts of security and privacy compromises.
  • In 2013, my colleagues and I released The Security Cards: A Security Threat Brainstorming Toolkit. The toolkit consists of 42 physical cards designed to assist in computer security-related brainstorming and education. The are four card suits: Human Impact, Adversary's Motivations, Adversary's Resources, and Adversary's Methods.
Fiction. I believe that fiction can help catalyze conversations and deep thinking about the relationship between people, society, and technology.
