My name is Jianhan Yu. I got my first phd degree at Southwest Jiaotong University, then I got my PHD at 2022 with Ted Stathopoulos at Concordia University, Canada. Then I got a position at Southwest Jiaotong University as an assistant professor. I majored in environmental wind engineering. I had conducted research with wind tunnel test and computational method before. And I would like to do some field measurement in the next few years. This course would be very helpful for my future study. I appreciate for the organiser for the opportunity. This is also a good opportunity to communicate with researchers from Hong Kong.
