Catalyzing Computing for Brain-Computer Interfaces

Series: Department Seminar

Speaker: Abhishek Bhattacharjee, A. Bartlett Giamatti Professor of Computer Science, Yale University

Date/Time: Dec 01 11:00:00

Location: CSA Auditorium, (Room No. 104, Ground Floor)

Abstract:
Brain??computer interfaces have the potential to treat debilitating neurological disorders, reveal new insights into brain function, and ultimately redefine the relationship between biological and artificial intelligence. Realizing this vision requires computer systems that carefully balance power, latency, and bandwidth to decode neural activity, stimulate neurons, and control assistive devices with precision.

This talk presents my groups design of a standardized, general-purpose computer architecture for future brain interfaces. Our architecture supports the treatment of multiple neurological conditions??most notably epilepsy and movement disorders??and is built around end-to-end hardware acceleration, spanning from the microarchitectural level to distributed systems. We validate these ideas through custom chip implementations and real-time experiments interfacing our chips with the brains of two human patients in the operating room.

Speaker Bio:
Abhishek Bhattacharjee is the A. Bartlett Giamatti Professor of Computer Science at Yale University. His research group designs computer systems for both high-performance data center servers and low-power processors used in implantable brain–computer interfaces. Their work has been deployed in billions of microprocessors and operating systems worldwide, earning Abhishek the ACM SIGARCH Maurice Wilkes Award in 2023. Abhishek teaches courses in computer architecture and computer systems, and has received the Dylan Hixon 88 Award—Yales highest teaching honor across the natural and physical sciences.
