NEWS: Our lab team won 2nd place award in CVPR 2022 LOng-form VidEo Understanding (LOVEU) challenge track3 (2nd in Recall@1 and 1st in Recall@3) [tech report]. Congratulations Hyeonyu, Jongeun and Jeonghun!

NEWS: Starting from Aug. 2021, I joined Artificial Intelligence Graduate School and Department of Computer Science and Engineering at Ulsan National Institute of Science and Technology (UNIST) as an assistant professor. Currently I am looking for self-motivated and curiosity-driven graduate students and undergraduate interns to join my group. If you are interested, please send me an email with your CV and transcript.

Currently, I am
an assistant professor in Artificial Intelligence Graduate School and Department of Computer Science and Engineering at Ulsan National Institute of Science and Technology (UNIST). Previously, I was an applied scientist at Amazon Alexa AI and a lead research scientist at a start-up company, ObEN. Before then, I was a postdoctoral scholar in the Computing and Mathematical Sciences department at the California Institute of Technology working with Prof. Yisong Yue. I completed my PhD in 2016 at Toyota Technological Institute at Chicago, a philanthropically endowed academic computer science institute located on the University of Chicago campus, and my advisor was Prof. Karen Livescu. I did my master in Computer Science at USC and bachelor in Computer Science & Engineering and Mathematics at POSTECH.

My main research interests span various problems related to the fields of Machine Learning and applications to Computer Vision and Language Processing. Specifically, I am interested in Deep Learning, Generative Models, Multimodal Learning, Transfer Learning, and Spatial-Temporal Data Analysis.
