My research focuses on developing algorithms and models that promote cooperative intelligence in mixed teams of humans and autonomous robotic vehicles. I currently work in three problem areas:
-cooperative sensing and perception in human-robot teams
-modeling and prediction of human decision making and task performance
-robust fusion of complex information in dynamic sensor networks
I'm looking for motivated PhD students, MS students, and undergraduates with strong backgrounds in engineering, physical science, computer science, or applied math to join my new research group at CU Boulder. If you're interested, please e-mail me your resume along with a brief (~1 paragraph) description about yourself, your goals and your specific research interests -- no form letters please!

MS students Matthew Aitken and Nicholas Sweet successfully defended their MS Theses on July 19 and 20, respectively.
Matt's thesis: "Assured Human-Autonomy Interaction through Machine Self-Confidence"
Nick's thesis: "Semantic Likelihood Models for Bayesian Inference in Human-Robot Interaction"
We all wish them both the very best as they kick off exciting futures in robotics!
