Nima Mesgarani

Associate Professor Of Electrical Engineering

Nima Mesgarani’s research is focused on the exploration of human speech communication. He studies representational and computational characteristics of the human brain areas involved in naturalistic speech communication.

He integrates these attributes into novel mathematical models used in machine emulation of speech communication. Better models of the underlying neural mechanisms involved in speech processing can critically impact research in artificial intelligence, neurolinguistics, systems neuroscience, translational medicine, and brain-computer interfaces.

Neurophysiology of Speech Communication

The process by which acoustic signals received by a listener are transformed into linguistic and non-linguistic categories is mainly unknown. Using the latest advances in invasive and non-invasive human recording techniques, Mesgarani’s group aims to uncover fundamental characteristics of cortical speech processing that enable a listener to extract information from the speech signal.

Neuro-inspired Computational Models

Mesgarani’s research in this area focuses on advancing and refining artificial neural network models used to emulate the cognitive abilities of humans. Furthermore, it is crucial to understand better the representation and transformation performed by these models to identify their limitations and compare them accurately with their biological counterparts, thereby reducing the performance gap between biological and artificial computing.

Brain-Computer Interfaces

A better understanding of how speech communication occurs in healthy brains enables better therapeutic approaches to help those suffering from speech and language disorders or those who suffer from peripheral and central auditory pathway disorders. Mesgarani’s research includes better neural decoding algorithms and novel solutions for cognitively controlled hearable devices.

Nima Mesgarani is an associate professor of Electrical Engineering at Columbia University. He received his Ph.D. from the University of Maryland, where he worked on neuromorphic speech technologies and neurophysiology of the auditory cortex. He was a postdoctoral scholar at the Center for Language and Speech Processing at Johns Hopkins University and the University of California San Francisco neurosurgery department before joining Columbia in the fall of 2013.
