Hello, this is Yingchaojie Feng (封颖超杰). I am currently a Ph.D. candidate in Computer Engineering at Zhejiang University under the supervision of Prof. Wei Chen in VAI group. Before that, I received my B.S. degree from Zhejiang University of Technology.

My research interests include visual analytics and natural language interaction. Specifically, I design and develop visual and interactive systems to facilitate the understanding and utility of NLP models for downstream tasks, including creative tasks (e.g., text-to-image, painting-to-poetry) and analytical tasks (e.g., NLI-based data analysis).
