About Us

Welcome to the Perception, Neuroimaging, and Modeling (PNM) lab at Georgia Tech. We investigate the brain processes that allow us to perceive the world. In particular, our focus is on the top-down mechanisms that modulate the normal visual process. We use a variety of methods such as functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS), psychophysics, and computational modeling. One particular focus of the lab is on open science by sharing data and code, as well as pre-registering our studies.

Open Ideas

We share our ideas. Take a look at our Projects page to see what we are working on. We pre-register our studies before collecting data and would love your feedback on them. Check out our Blog or Twitter feed to see what we think about recent issues in the field.

Open Data

We share our data. Every piece of behavioral data that we collect is uploaded on our GitHub page. We use NeuroVault to upload maps from our functional MRI studies.

Open Code

We share our code. We are scientists and our code is not perfect but we make every effort to write clean, easy to follow, and correct code. You can download our scripts from our GitHub page.
