Sungchul Kim

Data Scientist

San Jose

Sungchul is a data scientist at the Systems Technology Lab of Adobe Research. I received my Ph.D. in Computer Science and Engineering at Pohang University of Science and Technology (POSTECH) in summer 2015 under the supervision of Prof. Hwanjo Yu. My thesis was on constructing mutation profiles for top-k patient search and stratification of cancer subtypes.

My research interests focus on user behavior modeling and visitor stitching and include representing and analyzing data by using data-mining techniques including regression, ranking, and dimensionality reduction, and also I have been working on recommender system, online advertisement and named entity recognition.
