Scientific research. I am interested in formal mathematical analysis of two unexplained phenomena: consciousness and emergence. To understand the biological basis of consciousness, my research has focused on how the spatiotemporal scale of conscious experience emerges in the brain, issues around falsifying contemporary theories of consciousness, and using information theory to track the differences in neural activity between consciousness and unconsciousness. Another central goal of my research is to develop formal measures of emergence. Specifically, I have focused on how dimension reductions can improve causal models of Boolean networks, how macroscales can act as error-correcting codes to reduce the noise in causal relationships, as well as under what conditions of connectivity networks develop informative macroscales. Recently, I have become interested in deep learning and creating toolkits to examine the causal structure of artificial neural networks. This has also led to developing a theory of the neural purpose of dreaming, wherein the goal of dreams is to combat daily overfitting of the brain, which I also think just might be the purpose of fictions themselves.
