Sung-eok Jeon, Ph.D.

Short Bio.:
Sung-eok Jeon received B.S. degree from Electronic Engineering (EE) Department at Yonsei University, Seoul, Korea; M.S. degree from EE Department,
KAIST, Daejeon, Korea; and Ph.D. degree from the School of ECE at Georgia Institute of Technology, Atlanta GA. He worked at Microsoft between Jan/2008 and Aug/2015 about Windows system reliability analysis
(large system reliability analysis and probabilistic modeling; applying machine learning models on data analysis and modeling), data mining, and software engineering on data pipelines, user-mode debugging, and bug-filing systems.
He is now at Facebook since Aug/2015. 
His research interests are statistical modeling of large and complex systems based on the probabilistic graphical models in machine learning;deep-learning on complex data with variant neural networks; 
message-passing algorithms over graphical models; data modeling/analysis/mining and information retrieval with machine learning approaches.
