Biography

I am a staff engineer at Samsung Research (Data Intelligence team). Before joining Samsung Research, I earned my Ph.D. from KAIST Data Intelligence Lab in 2024 and was fortunate to have been advised by Professor Steven Euijong Whang. I received my bachelor's degree in Electrical Engineering from KAIST in 2018.

My research interests lie in Data-centric and Responsible AI. While model-centric AI focuses on improving the training algorithm to increase model accuracy, data-centric AI focuses on improving the data itself to increase model accuracy. Moreover, I believe that Responsible AI problems such as fairness and robustness also need to be solved in a data-centric fashion as AI is only as good as its data. To this end, my current research aims to develop fundamental solutions to realize Responsible and accurate AI from various data-centric perspectives, which include data acquisition, labeling, and cleaning.
