I'm currently a PhD student from Computer Science Department at Rutgers University (since 2017 Fall), under the supervision of Prof. Mubbasir Kapadia. Before that, I received my Bachelor of Engineering in Computer Science and Technology in 2017, and Bachelor of Arts in TV Editing and Directing (Post-production of Television) in 2016, both from Communication University of China.

I'm currently a Research Intern at Salesforce Research working with Dr. Juan Carlos Niebles and Dr. Roberto Martín-Martín on instructional video understanding (I'm a part of the AI for Multimodal and Temporal Reasoning research team).

I've done internships at NEC Laboratories America (Mentors: Dr. Asim Kadav and Dr. Farley Lai), and Google YouTube (Mentors: Dr. Wei-Hong Chuang and Dr. Hassan Akbari).

I'll graduate soon - welcome to email me for job opportunities! ;P

Research Interests:

Deep Learning, Computer Vision, Multimodal Understanding.

  • Instructional video representation learning

  • Multimodal scene boundary detection in long videos

  • Group activity recognition from videos

  • Video spatiotemporal reasoning and object tracking

  • Crowd trajectory prediction with computer vision techniques and virtual simulations

  • Learn low-dimensional vector representations for graphs with innovative applications (e.g., automatic floorplan design)

  • Foresee human interaction patterns in online environment (e.g., information/product adoption patterns)

Particularly, I'm passionate about the next-generation machine intelligence, especially machine learning and reasoning that enables a deeper understanding of the semantics of data (video, image, text, graph, human skeleton and other modalities). Currently, my research is focusing on multimodal video understanding and representation learning.
