Research Interests

Nonlinear Dynamics

Nonlinear dynamics is an area of dynamical systems analysis dealing with systems that have nonlinear components. Examples of such systems include logistic growth, neuron spiking, and chaos. A portion of my research is geared towards creating new methods for understanding nonlinear systems, and applying methods developed for understanding physical systems to psychological and behavioral systems.

Nonverbal Synchrony

My applied interests revolve around nonverbal synchrony. Nonverbal synchrony refers to a synchronization and coordination of motion between two individuals engaged in information transfer with one another. High levels of nonverbal synchrony have been associated with many positive outcomes between individuals. My current nonverbal synchrony projects involve treatment disparity in patient-physician dyads, individual differences in conversation dynamics, and the roles oxytocin plays in conversation dynamics.

Structural Equation Modeling

Structural equation modeling (SEM) is a general framework for hypothesis testing and statistical modeling. A portion of my research involves using SEM to analyze nonlinear dynamical systems and model latent differential equations. I also contribute to the OpenMx SEM software development project by creating tutorial videos that I host on YouTube (Link at the top of this page).
