  • Dr Ting Wang of the University of Otago Visits Peking University

    19/10/2016 - The New Zealand Centre of Peking University hosted Dr Ting Wang, from the University of Otago, as a 2016 Visiting Research Fellow. Her guest lectures were well attended and provided Peking University students a refreshing insight into a specialist field of research prime for China-New Zealand cooperation.

    The New Zealand Centre hosted Dr Ting Wang, who is a NZC Visiting Research Fellow specializing in mathematics and statistics. Her lecture host is Professor Shiyong Zhou of the Department of Geophysics at Peking University. She made a very good use of her time at PKU and took a very active part in the academic activities together with her host. She delivered two lectures: “Long-term Spatiotemporal Variation of Seismic Activity” on 14 October and “From China to New Zealand: Post and Pre-seismic Signals in Auxiliary Data” on 19th October.

    Dr Ting Wang is originally from China. She did her undergraduate studies and her Masters specialising in mathematics and statistics at Beijing Normal University. She finished her PhD in statistics at Massey University and worked as a Research Fellow in Japan. She mainly researches epidemic processes such as earthquake and volcanic hazards.

    Dr Tina Wang delivers a lecture to students at Peking University.

    Her first lecture has two main sections: a state-transition model for earthquakes, and a state-transition model for non-volcanic tremors. She shared her experience of using Hidden Markov Models (HMM) to analyse seismic cycles. She explained the application behind the models by relaying to two case studies: her investigation of a Markov-modulated Hawkes process to capture the cyclic parent-generating-offspring features of the temporal behaviour of earthquakes, and an examination using different types of HMM of spatlotemporal migration of non-volanic tremors to explain how it distinguishes segments of tremor source regions and identifies the spatiotemporal migration pattern among the segments.

    In her second lecture, she started by sharing case studies in applying statistics to forecast earthquakes. She shared her studies in post-seismic effects of a Chinese case (Tang shan), in which she used signals from the groundwater level created by the earthquakes. She also shared her more recent forecasting investigation of using GPS measurements of ground formation in the Central North Island of New Zealand (Taupo) comparing it with Southern California and Kanto in Japan. Her presentation was well-structured and successfully stimulated audience interest both in and outside of her specialised field.

    Dr Tina Wang prepared her lecture as part of a Visiting Fellowship with the New Zealand Centre. If you are a member of the academic staff from any of our eight partner institutions and you are interested in attending a fellowship at Peking University, get in touch with our liaison officers to learn more about the application process. Visiting fellowships for New Zealand academics are held year-round at Peking University, across a broad range of departments, forming a significant contribution to the advancement of academic exchange between China and New Zealand.
