Matthew Leonard

Matthew Leonard is an Associate Professor at the University of California, San Francisco (UCSF) School of Medicine, affiliated with the UCSF Weill Institute for Neurosciences. With a PhD in Cognitive Science from UC San Diego, his work focuses on neural systems in auditory and speech categorization, leveraging intracranial recordings and neuromodulation techniques like vagus nerve stimulation.

• Education: BA (Cognitive Science, Occidental College), MS & PhD (Cognitive Science, UC San Diego)

His research spans auditory neuroscience, speech processing, and cognitive neurosurgery, supported by grants such as NIH R01DC015504 and DARPA N66001-17-2-4008. Key contributions include understanding neural encoding of speech sounds, cortical dynamics in bilingualism, and ethical considerations in intracranial electrophysiology.

Recent publications analyze melody encoding and single-neuron speech representation, with collaborations across UCSF, UCSD, and UCI. He works in the Chang Lab, advancing brain-computer interfaces and neural rehabilitation.

His work has strong implications for speech disorders, language acquisition, and neuroethics, with over 150 citations on his 2019 Neuron paper alone.
