Broadly, I am interested in the perceptual processes that enable us to coordinate with others. For example, how we understand actions, or how social contexts might modulate our perception of our surroundings.

Most of my work is experimental, but I also use meta-analysis to test theoretical accounts of widely studied phenomena.

A priori power analysis for ANOVA interaction effects with the anovapowersim R package: a short introduction

Preprint | 2026

Although power analysis has become increasingly accessible over time, researchers still find it challenging to compute power for complex ANOVA interactions. anovapowersim is an R package that enables users to easily specify between, within, and mixed interactions of varying complexity and simulate power based on a target effect size.
