## About

### Overview

Dr Shiqiang Yan obtained a BEng in Marine Environmental Engineering and Msc in Environmental Sciences from Dalian Maritime University, China, in 1999 and 2004, respectively. He received his PhD degree in hydraulics from City University London in 2007. Immediately afterwards he joined the Hydrodynamic Research Group of the same university as a post doctoral research fellow and Leverhulme Trust Early Career Research Fellow focusing on the research on wind-wave-current interactions with offshore structures with Prof. Qingwei Ma. He was appointed as lecturer in Hydrodynamics at City University London in October 2012.

Dr Shiqiang Yan has engaged in research on marine pollution modelling and control since he joined Zhejiang Ocean University, China, as an associated lecturer in 1999. In his early work, he studied the tidal current modeling, the behaviors of marine pollutions and control technologies. From 2004 when he jointed City as a PhD student, he started his research on numerical simulations of fully nonlinear water waves and their interaction with offshore structures. He has contributed to the development of two numerical methods modelling extreme/breaking waves with/without wind and currents, wave loads on and dynamic responses of offshore to steep waves.
