About

Hi all! This is Leeje. I am a Ph.D. student in Computer Science at the University of Minnesota, advised by Prof. Yao-Yi Chiang in the Knowledge Computing Lab. My research spans computer vision, natural language processing, and multimodal learning, and I am particularly motivated by building machine learning models that address the needs of real-world domains involving geospatial data and the medical domain.

Research Interests

Computer Vision Vision-Language Models Natural Language Processing Machine Learning Multimodal Learning Spatial Data Analysis Geospatial AI Medical AI
