Information Systems Laboratory

Information System Laboratory (ISL) was founded in 2016 as a part of the Department of Electrical and Computer Engineering at Ajou University. Our research focuses on algorithms for information processing, their mathematical analysis, and a broad range of applications. Core topics include information and coding theory, machine/deep learning, probabilistic graphical model, optimization, and wireless communications.

[Openings] There are 2~3 open positions for Ph.D./M.S. students and Post-doctoral researchers starting Fall 2018/Spring 2019. I am looking for students with a strong mathematical background (e.g., probability and linear algebra). Please see our recent publications and projects. Each student will be supported for full tuition and stipend. If you are interested in, please feel free to contact me.

[Openings] We are looking for undergraduate intern students who are interested in i) 6G wireless communications; ii) Machine/Deep learning; iii) Coding for memory; iv) Coded distributed computing. Each student will be supported for stipend and encouraged to participate in international conferences. If you are interested in, please feel free to contact me.
