My overall research program has two branches. The first is Space Exploration and Analog Environments. The second is that of Entertaining and Affective Intelligent Interfaces, and is a continuation of the work I was doing before coming to UH.

Recently, I have been involved in a number of projects investigating how technology can best support human space exploration, in particular in overcoming challenges related to isolation, high-latency low-bandwidth communications, critical data overload, team selection and training, and hazardous/stressful environments (see my recent papers for several examples). In addition to this research, I have acted as a 'matchmaker' between computer science students and astrobiology research projects. As a co-investigator at the UH-NASA Astrobiology Institute, I have identified a number of needs in the NAI community that are suitable for research projects, ranging from well-specified software engineering projects appropriate for an undergraduate student to open-ended research projects appropriate for a PhD thesis.

Past computational astrobiology projects include:

As part of this effort to bring astrobiologists and computer scientists together, I am organizing the Computational Astrobiology Summer School, a three-week program designed to introduce computer science graduate students to astrobiology.

The second branch of my research program is that of Entertaining and Affective Intelligent Interfaces. This includes the continuation of my earlier research on computational humor as well as work on other forms of intelligent interface. Projects include:
