Sung-eok Jeon, Ph.D.

Short Bio.:

Sung-eok Jeon received B.S. from EE at Yonsei University, Seoul, Korea; M.S. from EE at KAIST, Daejeon, Korea; and Ph.D. from the School of ECE at Georgia Institute of Technology, Atlanta GA.

He worked at Microsoft, Seattle, WA about Windows system reliability (large system reliability analysis and probabilistic modeling; applying machine learning models on data analysis and modeling), user-mode debugging, backend Windows services, at Facebook from 2015 to 2017 (filed over 10 patents), also at Uber and a startup, having worked on ML, backend of services and backend of platform. And he is now at Meta (Facebook), working as a software engineer with ML focus since Feb/2022.

His research interests are machine learning, feature engineering, deep-learning variations; statistical modeling of large and complex systems based on the probabilistic graphical models in machine learning; message-passing algorithms over graphical models; data modeling/analysis/mining and information retrieval with machine learning approaches.
