preprints
I make an effort to post my research early as a preprint whenever possible. Feel free to leave peer commentary on any of the preprints below or to email me with suggestions. They are all works in progress!

The NeuroFreq toolbox for MATLAB, introduced in this paper, enhances the analysis of M/EEG data through consistent implementation of multiple time-frequency (TF) transformation algorithms. It addresses the inconsistencies in current toolboxes by offering comprehensive features for linear and quadratic TF decomposition, along with utilities for resampling, averaging, baseline correction, and visualization across multiple channels. This toolbox simplifies TF analysis for newcomers and facilitates community comparison of various TF methods, demonstrated through applications to both synthetic and EEG data.

This study on PTSD in U.S. military veterans finds that somatomotor beta bursts (BBR) rates, observed during a cognitive control task, correlate with response direction and conflict monitoring. Increased BBRs are associated with greater posttraumatic stress symptoms and mediate the link between these symptoms and decreased conflict monitoring accuracy. The results suggest that cognitive control deficits in PTSD are due to a failure in adaptively disinhibiting target motor representations, indicating BBR as a potential marker for cognitive control assessment in various brain disorders.
