Welcome!
Welcome!
I'm a 5th-year Ph.D. candidate in Electrical Engineering at Columbia University, advised by Prof. Nima Mesgarani. My research is dedicated to transforming how people hear in complex acoustic environments. I develop brain-controlled hearing systems that decode neural signals in real time to determine the talker a listener is focused on. These systems then selectively amplify that voice, enabling effortless communication in noisy, multi-talker settings.
My work involves analyzing multi-channel time series data from audio signals and invasive brain recordings, bridging signal processing, auditory neuroscience, and machine learning. Recently, I’ve been exploring GenAI, with a focus on how foundation models and large language models can augment human auditory perception.
In industry, I interned at Bose in Summer 2024, where I developed feed-forward noise cancellation algorithms. I am currently with Meta Reality Labs as a Summer 2025 Research Intern, working on multimodal sensing for smart glasses.
Outside the lab, I enjoy listening to soulful music and experimenting with smoothie recipes. I hold a bachelor’s degree in Electrical Engineering from the Indian Institute of Technology (IIT) Palakkad, where I graduated as class valedictorian and received the Institute Gold Medal. I'm passionate about traveling, learning new skills, and connecting with people.
I invite you to explore my work, and I hope you enjoy your visit.
Sincerely,
Vishal Choudhari
