DOI: 10.1007/s10652-020-09771-5
Abstract: The quantification of turbulent mixing in nature is predicated by inherent randomness of causal events, and obtaining relevant turbulence statistics requires ensemble averaging of identical realizations that are unachievable in field observations or onerous in… read more here.

DOI: 10.1109/tmi.2016.2595329
Abstract: We propose an algorithm for electrical source imaging of epileptic discharges that takes a data-driven approach to regularizing the dynamics of solutions. The method is based on linear system identification on short time segments, combined… read more here.

DOI: 10.1167/jov.23.1.5
Abstract: Many studies have shown that observers can accurately estimate the average feature of a group of objects. However, the way the visual system relies on the information from each individual item is still under debate.… read more here.

DOI: 10.1175/jcli-d-17-0197.1
Abstract: AbstractWhen comparing climate models to observations it is often observed that the mean over many models has smaller errors than most or all of the individual models. We will show that a general consequence of… read more here.
