Unlike standard MR imaging, real-time fMRI techniques allow ongoing changes in brain activation to be monitored and used throughout an experiment. Potential applications include QA monitoring, neurofeedback, and dynamic experimental control.
My work focuses on developing comprehensive and flexible real-time fMRI software tools, and using these methods to ask questions about trained self-regulation of neuromodulatory regions.
Pyneal - real-time fMRI software
Open-source software for real-time acquisition and analysis of fMRI data.
Pyneal is a set of open source tools I developed for supporting real-time fMRI methods. It offers pre-built analysis routines, as well as the option of writing custom statistical models (using a provided template) that can be executed on each incoming volume. The output of the analyis is hosted via its own server, allowing experimental presentation software to access the results as needed.
Dynamic free gaze mapping
Wearable eye-trackers allow for more naturalistic viewing experiments, but present numerous analytic challenges for summarizing gaze behavior over time. The solution requires figuring out transformations that map between the coordinate systems of the eye-tracker, static reference images, and the physical world.
We use these mappings to measure viewing patterns as participants freely explore works of art in a museum setting
Face processing in visual art
Merging art & neuroscience to tackle questions related to perceptual phenomena.
As a postdoctoral researcher with the Bass Connections: Art, Vision, and the Brain project, my work focuses on studying patterns of eye-movement evoked by artistic representations of faces. In addition, I mentor a team of undergraduate scientists as they investigate what makes a face a face.
