Prof. Kausik Si

Dr. Kausik Si is a neuroscientist and Scientific Director at the Stowers Institute for Medical Research. Renowned for his groundbreaking studies on the molecular basis of memory, Dr. Si investigates how stable, self-sustaining protein aggregates, such as prion-like proteins, can encode long-term information in the brain. His work has revealed that specific RNA-binding proteins, including CPEB, exhibit prion-like properties that are critical for the persistence of synaptic changes underlying memory. By bridging molecular biology, neurobiology, and biophysics, Dr. Si has brought new insights into the physiological roles of protein aggregation, reshaping our understanding of memory storage and functional amyloids.
