    • About

    Over the past six years I have created tutorials on the imaging modalities I have used in my research, including fMRI, structural MRI, functional connectivity, diffusion analysis, and multivariate pattern analysis (MVPA). These tutorials consist of both a written description of the method, and a series of videos demonstrating how to use the technique or software. These tutorials have been used by universities and laboratories all over the world. I have also spent several years as a consultant for labs using different imaging methods to examine a wide range of research questions. This has given me extensive experience with introducing students to imaging methods and with training researchers in more advanced techniques.

    Research Overview

    My research applies computational modeling to fMRI data by empirically testing model predictions and evaluating how well model outputs fit neuroimaging data. I spent the latter half of my graduate studies at Indiana University extending our computational modeling work of the medial prefrontal cortex (mPFC) to primate neurophysiological studies as well as translational studies in drug addiction. I collaborated with Dr. Ben Hayden’s lab at the University of Rochester to implement our modeling work into a primate neurophysiological study, which I designed and analyzed. Another facet of my research has been the use of individual difference measurements to examine how neuroimaging data is modulated by test scores, personality traits, and task performance. For example, my studies with collaborators at Ohio State University have found that measures of withdrawal and approach anxiety modulated amygdala activation depending on whether aversive stimuli approached or receded from the participant.

    At Haskins Laboratories I applied these computational modeling and neuroimaging skills to the analysis of structural and functional MRI data from reading experiments. In addition to studies of the association between structural measurements (e.g., grey matter volume and fractional anisotropy) and reading skills, I recently applied computational model predictions to a combined eye-tracking and fMRI study. In this approach, we used different models (e.g., word surprisal calculated by n-gram or context-free grammar) to modulate the hemodynamic response to individual words. Using this method, our data has shown that the different models are fits for distinct anatomical regions, particularly the left inferior frontal gyrus and left anterior temporal lobe. This suggests that these regions perform fundamentally different processing of surprisal as calculated by the models.
