7+ years front office experience at Citadel and a leader in the firm's alternative data research. Currently, I manage the data featurization team, extract alpha-generating features from trillion-scale alternative data, and develop algorithms to enhance signal quality. My research outputs (including forecasts, machine learning algorithms, AI-based signals and web apps) are deployed in production for forecasting and trading; some of which are used weekly by >30% members of the Citadel Investment Group. Previously at Center for Network & Data Science at University of Notre Dame, I developed network models to solve interdisciplinary problems from tracing information diffusion on investor network to preventing species invasions via global shipping. My research has been published at top journals such as Science Advances (including a paper ranking top 5% impact by Altmetric), as well as top data mining conferences such as KDD. I also worked with leading research institutes: with U.S. Army Research Lab on anomaly detection using higher-order networks, and with IBM Research on cell phone location data mining. I serve as the reviewer for top data mining & AI journals since 2013, and serve as the organizer and on the program committee board for top data mining conferences since 2017.Website: http://www.jianxu.net/en/CV: http://jianxu.net/en/files/JianXu_CV.pdf
