Overview
Dr. Cogan's research focuses on speech, language, and cognition. This research uses a variety of analytic techniques (e.g. neural power analysis, connectivity measures, decoding algorithms) and focuses mainly on invasive human recordings (electrocorticography - ECoG) but also uses non-invasive methods such as EEG, MEG, and fMRI. Dr. Cogan is also interested in studying cognitive systems in the context of disease models to help aid recovery and treatment programs.

Distinct neural processes link speech planning and execution.
Preprint · July 3, 2026 Speaking is the primary way that humans communicate. This communication is enabled by a production system that can plan and execute unique combinations of speech sounds. Although a distributed network of brain regions has been implicated in speaking, it is ...

Journal article Epilepsia · May 2026 OBJECTIVE: Interictal epileptiform discharges (IEDs) are transients observed on the electroencephalogram (EEG) of patients with epilepsy. IEDs have traditionally been recorded from scalp or intracranial EEG macrocontacts, which coarsely sample neural activ ...

Journal article J Neural Eng · April 10, 2026 Objective. High-frequency oscillations (HFOs) are a potential biomarker of the epileptogenic zone (EZ) in patients with focal epilepsy. Previous research has estimated that HFOs arise from regions as small as a single cortical column (1 mm3), making events ... Full text Link to item CiteRecent Grants
