Our research examines the neural mechanisms that underlie flexible behavior and cognition.
We are interested in how humans carry out and maintain goal-directed behaviors and how the brain reacts to sudden events that put their goals in peril (such as unexpected events or action errors).

We investigate the dynamic interplay between brain networks that subserve:
- The monitoring of the external and internal environment.
- The evaluation of action outcomes.
- The adaptation of ongoing behavior and cognition in the short and long term.
Wessel, Psychophysiology 2018
We use a variety of methods to study these questions, including (but not limited to):
- Scalp-recorded Electroencephalography (EEG).
- Invasive recordings of brain activity (ECoG and DBS-LFP recordings).
- Transcranial magnetic stimulation (TMS).
- Functional Magnetic Resonance Imaging (fMRI).
- Computational modeling.
- Pupil tracking.
Finally, we study how pathological processes, brain lesions, and (ab)normal aging affect these networks.
