Currently interested in: - infinitesimal futamura projections on staged abstract interpreters - the symmetries between Butcher trees, Dyck words, Cayley Operads, and Pachner moves - Kunita flows as time-unrolled RG flows - the statistics of unknown non-stationary processes

- mirror-descent and the geometries of generalized deformed-log entropies - color theory - online streaming methods for topological data analysis - developmental models of automorphic forms and harmonic oscillators - physical game theory models (eg games as spinning tops)
