Hi, I am Ke Xu (徐科)
I am curently a researcher at Huawei. I am leading the DataArts Insight team to build an intelligent, A I-augmented and easy-to-use Business Intelligene (BI) platform in the Huawei Cloud. I was a Postdoctoral Research Associate in the Visualization and Data Analytics Research Center (VIDA) at New York University (NYU), advised by Prof. Enrico Bertini and Prof. Claudio Silva.
My research interests, broadly, are Data Visualization, Human-Computer Interaction, Big Data Analytics and Machine Learning. Specifically, I am interested in domains of visual anomaly detection, explainable AI, automated data insights, temporal data analytics and healthcare.
I earned my Ph.D. in Department of Electronic and Computer Engineering from the Hong Kong University of Science and Technology (HKUST) in 2019, where I worked with my supervisor Prof. Huamin Qu and VisLAB. Prior to my Ph.D. studies, I received my B.S. in Electronic Science and Engineering from Nanjing University (NJU) in 2015.
