Bio

Xin (Eric) Wang is an Assistant Professor of Computer Science and Engineering at UC Santa Cruz. He obtained his Ph.D. degree from UC Santa Barbara and Bachelor's degree from Zhejiang University, both in Computer Science. His research interests include Natural Language Processing, Computer Vision, and Machine Learning, with an emphasis on building embodied AI agents that can communicate with humans using natural language to perform real-world tasks. He worked at Google AI, Facebook AI Research, Microsoft Research, and Adobe Research.
Xin has served as Area Chair for NAACL 2021, CoNLL 2021, NLPCC 2021, and EMNLP 2020, Senior Program Committee (SPC) for IJCAI 2021, and Session Chair for EMNLP 2020 and AAAI 2019. He organized multiple workshops and tutorials at ACL, CVPR, ICCV, AACL, etc. He received the CVPR Best Student Paper Award in 2019.

Research Interests

Xin's research interests include Natural Language Processing, Computer Vision, and Machine Learning, with an emphasis on building multimodal embodied agents that can communicate with humans using natural language to perform real-world tasks.

Natural Language Processing (natural language grounding, knowledge-based reasoning, fairness and bias)
Computer Vision (vision and language, visual navigation and robotics, activity understanding in videos)
Machine Learning (multimodal machine learning, self-supervised learning, reinforcement learning, deep learning)
