Current and past research students, and what they worked on

Most of my research happens through students, and most of it is interdisciplinary: a typical thesis pairs an AI question with a supervisor from ecology, law, psychology, or engineering. The list below covers everyone I have supervised, with their topic, co-supervisors, and a link to the thesis or report where one is available. My thesis roster is currently full, so I am not taking on new PhD or MSc students except in exceptional circumstances.
