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 trading behavioral analysis, Hawkes process in finance and fractal activity time geometric Brownian motion (FATGBM) pricing models. 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 her research is to improve pricing and risk modelling framework for financial markets. Recently, she mainly focuses on trading behavoiral patterns in crypto markets and blockchain-based financial network reactions to systemic events.

My research interests include time series models of financial returns, trading behavioral analysis and Hawkes process in finance. I have 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 existing pricing and risk evaluation framework, especially from the systemic perspective, for financial markets. I work on applications of a variety modelling techniques, such as time series and stochastic models, optimization strategies, machine learning algorithms, in finance. I am experienced in finance data analysis and computing techniques.
