I enjoy solving exciting computer security problems of deep learning and cloud computing. I am currently working under the supervision of Prof. Tudor Dumitraș. Before moving to Maryland, I received my B.S. in Electrical Engineering and Computer Science from Seoul National University in Feb. 2015. During my undergraduate years, I carried out several projects with LG Electronics Inc. (LGE) as a lead researcher. Also, I founded Openwise Inc. (in South Korea), a start-up company where I conducted and supervised research projects carried out with Samsung Electronics Co., Ltd. (SEC) as a Chief Technology Officer.
