Sung-eok Jeon, Ph.D.

Short Bio.:
Sung-eok Jeon received B.S. degree from 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, Seattle, WA, from Jan/2008 to 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 worked at Facebook from Aug/2015 to Oct/2017 (filed over 10 patents with Facebook patent lawyers and co-workers). He is now at Uber since Oct/2017. 
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.
