What is AI and Data Science? 

AI is really a science of data, where computer vision engages with visual data and NLP delves into linguistic data. Moreover, the vast array of data types including tables, matrices, tensors, graphs, and time-series pervades across industries and organizations, emanating from diverse sources. Unearthing value from such data constitutes the very essence of AI and data science.

Our current research interests are in NLP & trustworthy LLMs, recommender system, time-series & anomaly detection, and multi-modal learning.

Our lab is recruiting MS/PhD students and also undergraduate research interns. Please, contact me first if you want to join our lab. I am especially excited about working with exceptional (undergraduate or graduate) students. My goal for students is to maximize their potentials and abilities to draw out influential research results. Specifically, my research guidance emphasizes 1) identifying fundamental and important research problems by a thorough understanding of literature and working on real-world problems, 2) developing technical skills through comprehensive implementations and experiments, and 3) presenting and writing out ideas and results into top-tier conference or journal publications. 


Our lab has the strongest publication records nationwide in the area, and my students have won prestigious awards such as top prizes in world data mining competitions, awards at top-tier conferences, fellowships from Microsoft, Naver, and Samsung. We have maintained close relationships with academia and industry in the United States, and most of our PhDs have been offered full-time researcher positions at major industries in the United States (e.g., Amazon, Oracle, Adobe, Yahoo Verizon) or faculty positions at first-class universities  (e.g. UTexas, KAIST, Yonsei Univ., Pusan National Univ.).

Undergraduates interested in research interns are encouraged to apply after taking CSED342 Artificial Intelligence. (학부생 연구 인턴에 관심있는 학생은 CSED342 인공지능 수업을 들은 후에 지원하기를 권장합니다.)
