We’ve recently been interested how multiparameter models in many fields of physics (from systems biology to cosmology) have collective behavior which depends only loosely on their parameters; these sloppy models work in some ways for the same reasons that underly the continuum limits and the renormalization group. In materials physics, we are exploring plastic deformation and dislocation dynamics in metals – our models show fractal dislocation structures and earthquake-like crackling noise. We have recent interests in Bayesian and machine learning methods, applied to economics and also to experimental data analysis.
