I am a computational scientist interested in complex and stochastic systems, statistical inference, inverse problems and emergent phenomena. I am especially interested in using statistical computing to better understand complex human-based problems such as traffic management, economics and epidemiology.

Detecting Multi-Spin Interactions in the Inverse Ising Problem

2017

We consider inferring the coupling parameters of an Ising spin glass with multi-spin interactions. We show that the method of 'pseudo-likelihood maximization' is equivalent to fitting an identity presented by H. Callen in 1963, and present simulations testing the validity of this method of inference.

Cluster simulations of multi-spin Potts models

2015

We present simulation results for a generalized Potts model with 1-, 2-, and 4- site Hamiltonian terms, using an extended Fortuin–Kastelyn transformation. We report critical temperatures and exponents by MCRG and a comparison of thermalization times between the cluster-percolation method and a simple Metropolis alogrithm.

Testing procedures for extracting fluctuation spectra from lipid bilayer simulations

2014

Using simulated data we test the validity of a 'direct Fourier' method used to analyze simulated lipid bilayers with periodic boundary conditions. In a 1-D analogue we found that the plane-projected density of lipid head groups added high-q noise to fluctuation spectrum given by the direct Fourier method.
