Dr. Chelsea Yao
My name is Chelsea Yaqiong Yao. I am Associate Professor (Senior Lecturer) of Accounting and Finance and Director of PhD program at Lancaster University Management School. I was Visiting Research Professor in 2015 and hold the same position from 2019-present at New York University Stern School of Business. I received PhD in Finance from the University of Melbourne, Australia, and Master in Finance from Durham University, United Kingdom. I have published on momentum, contrarian, seasonality, mutual funds and firm’s ESG performance. My current research interests lie in ESG ratings, ESG disclosure, climate-related disclosure, green investments, machine learning, artificial intelligence, textual analysis, mutual funds, exchange traded funds, hedge funds, momentum, contrarian, profitability, and seasonality.
