Ymchwil
Anqi’s research interests include behavioural finance, sentiment 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. She believes that interpretations to irrational trading behaviour will provide insights to market inefficiency. Recently, she mainly focuses on Hawkes process of modelling interactions between price and investor sentiment jumps.
