I am a PhD candidate in the Department of Computer Science at University of Maryland in College Park, MD, USA. I am advised by Prof. Niklas Elmqvist. I am interested in visual analytics, where data science and HCI plays important role with information visualization. My research in human-data interaction focuses on cultivating a visual analytics approach for open-ended tasks in text mining. The visual analytics approach tries to augment and amplify human’s abilityby combining information visualization and statistical machine learning.
