Bio
I am currently a postdoc fellow at Coastal NLP group at University of Copenhagen, working with Prof. Anders Søgaard. I obtained my PhD degree in October 2023 at CUHK text mining group, supervised by Prof.Lam Wai. I obtained my bachelor’s degree at Harbin Institute of Technology in 2019, majoring in bioinformatics.
Currently, my research interest focuses on multimodal information retrieval and text mining problems, including social media based fashion analysis, multimodal dialogue systems, etc. I’m also interested in other aspects of NLP and IR in the multimodal domain.
Research Interests:
- Multimodal Information Retrieval
- Conversational IR
- Image-text based Multimodal NLP
- Natural Language Processing
- Machine Learning
