I am a portfolio manager at WorldQuant, a systematic investment firm. My work includes trading, risk management, portfolio construction, and alpha research by quantitative methods. Previously, I finished my PhD in 2019 in the Machine Learning Department at CMU, advised by Artur Dubrawski in the Auton Lab. My doctoral research involved the development of statistical machine learning techniques with a focus on multi-view methods in the areas of prediction, signal processing, unsupervised learning, and factor analysis. I applied these ideas in practical scenarios by collaborating with scientific institutions to create data-driven solutions to real-world problems.
