Dr. Yu received his bachelor’s degree and doctor’s degree in biology from the University of Science and Technology of China in 2000 and 2005, respectively. From 2005-2014, he conducted postdoctoral research at the Max-Planck Institute of Brain Research in Frankfurt, Germany (2005-2008) and the National Institute of Mental Health in Bethesda, USA (2008-2014). He joined the Institute of Automation, Chinese Academy of Sciences (CASIA) from Sep. Since then, he is a professor at the Brainnetome Center and National Laboratory of Pattern Recognition, CASIA.
1. Network mechanisms underlying neuronal information processing
A fundamental challenge for systems neuroscience is to explain functions of the brain by studying neuronal activities. While a huge amount of knowledge has been accumulated regarding the behavior of single neurons, it is still far from clear how the brain achieves its remarkable feat as an organ of information processing, as well as how its functions are interrupted in various pathological conditions. To fill such an explanatory gap, we need to understand how numerous neurons, often with different response properties, can form an orchestrated network to perform computation, and how such computation is regulated according to the behavioral context. To develop such an intermediate-level description of neuronal information processing is my long-term goal. To this end, my research combines highly parallel electrophyiological recordings from macaque brain and advanced computational/theoretical approaches (e.g., network theory, information theory, statistical mechanics, etc) to investigate the structure and operation of neuronal networks, with focuses on understanding both how the brain works in normal conditions and the network mechanisms underlying major mental disorders.
2. Brain-inspired computing
The brain is a powerful machine for information processing, while capability of individual neurons seem to be rather limited. To understand how information processing emerges from interactions from relatively simple elements is a key to develop brain-inspired computing systems. Regarding emergent properties in complex systems, statistical physics provides by far the most important insights. Among them, the theory of criticality has been suggested to be highly relevant for understanding the brain. Critical systems exhibit a variety of functional advantages in terms of information storage, transmission and processing. At the same time, experimental brain research has provided ample evidence suggesting that the brain is operating at or close to a critical point. We would like to study the mechanisms underlying brain’s critical state and how such a state can facilitate computation in a complex, non-deterministic system. The aim is to translatethis knowledge to computational power in man-made systems. That is, to study how to exploit the functional benefits of a critical system to develop more powerful, flexible and efficient computing machine for practical applications.
