Dr. Pei-Ching Chen's research focuses on two major areas. First, he continues to develop advanced experimental technology for earthquake engineering, covering a wide range of applications including shake table control methods with artificial intelligence, actuator control methods with image-based measurement feedback, and real-time hybrid simulation that incorporates physical experiments into numerical simulations. In addition, Dr. Chen's recent research has focused on vibration control of structures using either active or semi-active devices. Particularly, he has proposed and verified novel and practical control methods for active structural control. Dr. Chen also dedicates his efforts to developing novel active and semi-active control devices. His passion and dedication quickly establish him as one of the most valued and outstanding researchers in earthquake engineering laboratories.
