Hello! I'm a CS Ph.D. candidate at Georgia Tech working with Dr. Haesun Park and Dr. Alex Endert in the fields of text mining, machine learning, and visual analytics.

My research aims to help people explore and interact with large-scale data, focusing on improving interpretability, interactivity, and scalability, by designing and developing interactive systems that tightly integrate algorithm, visualization, and user interaction.
