Overview


I am a surgeon-scientist specialized in the treatment of epilepsy and movement disorders.  My laboratory conducts basic and translational neuroscience research on cortical inhibitory circuits.  We are interested in 1) understanding the cellular design of inhibitory circuits in mice and humans, and, 2) advancing interneuron transplantation as a therapeutic strategy for inhibitory circuit repair.

Shared latent representations of speech production for cross-patient speech decoding.

Journal article Nat Commun · July 16, 2026 Speech brain-computer interfaces (BCIs) can restore communication in individuals with neuromotor disorders who are unable to speak. However, current speech BCIs limit patient usability and successful deployment by requiring large volumes of patient-specifi ... Full text Link to item Cite

Thalamic interictal epileptic and non-epileptic events during NREM sleep in patients with focal epilepsy: a Stereo-EEG study.

Journal article EBioMedicine · June 2026 BACKGROUND: Thalamic recordings are increasingly incorporated into stereo-electroencephalography (SEEG) evaluations of drug-resistant focal epilepsy to guide neuromodulation targeting. Human thalamic electrophysiology, however, is poorly defined, limiting ... Full text Link to item Cite

Thalamo-cortical synchrony shapes seizure expression in human temporal lobe epilepsy.

Journal article Nat Commun · May 25, 2026 In drug-resistant temporal lobe epilepsy (DR-TLE), some seizures are clinically symptomatic while others remain electrographic despite arising from the same seizure-onset zone (SOZ), suggesting that clinical expression reflects network dynamics beyond seiz ...
