About Me

I am an Assistant Professor in the Department of Computer Science Engineering, Kyung Hee University, leading the Vision and Learning Lab. I obtained a Ph.D. from the Bradley Department of Electrical and Computer Engineering, Virginia Tech, in 2020 advised by Jia-Bin Huang. I am lucky to have the opportunity to work with Gaurav Sharma, Samuel Schulter, and Manmohan Chandraker from NEC Labs America. From March 2010 to July 2015, I completed my military duty at the Electronics and Telecommunications Research Institute (ETRI), the Republic of Korea as a computer vision researcher. Before that, I completed my master's degree at Seoul National University (SNU) advised by Sang-Uk Lee. During my master's course, I closely collaborated with Chang-Su Kim


Research Interests

Computer Vision and Machine Learning 

I am especially interested in human activity understanding, video representation learning, domain adaptation and mitigating biases in visual recognition.

I am also interested in object detection, semantic segmentation, scene understanding and other visual recognition problems.
