Dynamics of Consciousness

The structure and dynamics of consciousness are closely related to the structure and dynamics of neural activity. I study this relationship using mathematical and computational models.

Interactive Neural Networks

To study the behavior of neural networks (simulated brain circuits) in virtual environments, I developed and maintain a computer program called Simbrain, which is open-source, visually-oriented, and free. Simbrain is currently being developed in collaboration with students and researchers at UC Merced. Check out www.simbrain.net.

Visualizing High-Dimensional Objects

I have developed another computer program in collaboration with Scott Hotton called HiSee. HiSee projects high-dimensional datasets to two dimensions so that they can be visualized. The datasets I focus on allow me to study the relationship between possible brain states and possible conscious states.

Edmund Husserl

Edmund Husserl developed a systematic philosophy of consciousness at the turn of the 20th century. Though I have little time for it now, I launched and maintain a site, Husserl.net, which features a variety of interactive tools for Husserl scholars.

Argumentation Maps

Logicians have analyzed the structure of arguments and statements. But inter-argument relations have received little attention. As senior writer on the project I was involved in the development of a technique for mapping out academic debates.  The original maps can be viewed here.  An online version of the maps is available here.
