I have recently started a project analyzing the infinite limits of models of random networks.
• Preferential Attachment Processes Approaching The Rado Multigraph; submitted. ArXiv Link.
I am interested in evolution and pattern-formation within nonlinear and complex systems. With Andy Lewis-Pye and George Barmpalias, I have been analyzing a fascinating model of racial segregation first proposed by the Nobel-Prize winning economist Thomas Schelling:
• Digital Morphogenesis via Schelling Segregation, with Barmpalias and Lewis-Pye (FOCS 2014: 156-165, Arxiv Link)
• Tipping Points in Schelling Segregation, with Barmpalias and Lewis-Pye (Journal of Statistical Physics, February 2015, Volume 158, Issue 4, pp 806-852, Arxiv Link)
• From Randomness to Order: Unperturbed Schelling Segregation in Two or Three dimensions, with Barmpalias and Lewis-Pye, Submitted. Arxiv Link)
My background is in Model Theory, a branch of mathematical logic, and its applications to algebra. I’m interested in simple theories, geometric stability theory, the model theory of groups and fields, and the interplay between these.
