Professor

Youngmin Yi is a Professor in the Department of Artificial Intelligence at Sogang University, which he joined in September 2024. He is also with the Department of Computer Science and Engineering. Before joining Sogang University, he had been a professor at the School of Electrical and Computer Engineering at the University of Seoul since March 2010, where he was also with the Department of Artificial Intelligence and the Department of Urban Big Data Convergence.

He received his B.S. and Ph.D. in Computer Engineering from Seoul National University in 2000 and 2007, respectively. He was a postdoctoral researcher in the Parallel Computing Lab at the University of California, Berkeley from 2007 to 2009, and worked for the Multi-core Software group at Samsung Advanced Institute of Technology (SAIT) till February 2010.

On his sabbatical leave from 2016 to 2017, he had the privilege to work with Prof. Xipeng Shen at NCSU as a visiting scholar.

His research interests include on-device deep learning, heterogeneous parallel computing, an architecture-algorithm codesign methodology for Deep Learning systems, and various deep learning and ML applications.
