Year 2016

On 19th April, 2016, LESS members including Dr. Shao, celebrated the end of the Spring semester and had a farewell lunch @ Appelbee's Restaurant in honor of visiting scholar Zhongyuan Shen from Tongji University, Shangai, China. Zhongyuan came to visit LESS in October, 2015. During her six-month stay here, she worked with Dr. Shao on a journal paper about her disseratation work related to seismic anlaysis of immersed tunnels using multi-body discrete time transfer matrix method. The paper is to submitted soon.
