Anyone who has ever used Hamiltonian Monte Carlo samplers before has probably encountered the so-called tuning problem: in short, it is not at all obvious how to pick the algorithm’s … Read More
Very fortunate to have Bob Carpenter (Flatiron Institute) visiting Rutgers Camden during the week of March 18th. Seminar details are linked here.
Will be taking a sabbatical leave from Rutgers for the academic year 2024-2025. As much as I enjoy teaching, it seems opportune to devote my full effort to research, particularly … Read More

Very fortunate to have Sonja Cox (University of Amsterdam) visiting Rutgers Camden during the week of Oct. 16th. Seminar details are linked here.
With Tore Selland Kleppe (Stavanger, Norway), released a preprint presenting 2.5/3.5-order L^2-accurate Randomized Runge-Kutta-Nyström methods to approximate the Hamiltonian flow within unadjusted Hamiltonian Monte Carlo and unadjusted kinetic Langevin chains.
Together with Katharina Schuh (TU Wien), released a preprint on a nonlinear generalization of Hamiltonian Monte Carlo for sampling from nonlinear probability measures of mean-field type.
Together with Stefan Oberdörster (Bonn), released a preprint presenting a new tool for total variation mixing time analysis of Metropolis-adjusted Markov kernels via couplings without restrictive assumptions on either the … Read More
Together with Milo Marsden (Stanford), released a preprint that constructs a randomized time integrator for Hamiltonian MCMC and analyzes the L^2-Wasserstein contractivity and asymptotic bias of the corresponding unadjusted Hamiltonian … Read More
