Biography
Dr Anqi Liu holds BSc in Mathematics and Applied Mathematics from the Northwest University, China; MSc and PhD in Financial Engineering from Stevens Institute of Technology, USA. She received Stevens Innovation and Entrepreneurship Scholarship for 4 years during her PhD.
Anqi’s research interests include time series models of financial returns, trading behavioral analysis and Hawkes process in finance. She has been collaborating with a number of financial researchers in the area of quantitative finance and computational finance, and has published a series of papers in international journals and conferences. The overall goal of this research line is to improve the existing pricing and risk modelling framework for financial markets. Recently, she mainly focuses on modelling Hawkes-type extremal returns, and hedging strategies of fractal activity time geometric Brownian motion (FATGBM) pricing models.

My research interests include time series models of financial returns, trading behavioral analysis and Hawkes process in finance. I has been collaborating with a number of financial researchers in the area of quantitative finance and computational finance, and has published a series of papers in international journals and conferences. The overall goal of this research line is to improve the existing pricing and risk modelling framework for financial markets. I implement a variaty of modelling techniques, such as time series models, stochastic models, machine learning algorithms, in analysis of financial markets. I am experienced in using advanced computing techniques to explore valuable insights in financial market data.
