Dong-Wan Choi is an Associate Professor in the Department of Computer Engineering at Inha University.

Prior to joining Inha University, he worked as a research associate with Dr. Thomas Heinis at Imperial College London from 2016-2017, and as a postdoc fellow with Dr. Jian Pei at Data Science Research Group of Simon Fraser University from 2015-2016. In 2014, he earned his Ph.D. in Computer Science from Korea Advanced Institute of Science and Technology (KAIST) under the supervision of Dr. Chin-Wan Chung. His Ph.D. dissertation is about processing and managing a large spatial database, which was honored with the annual Outstanding PhD Thesis award from the CS department at KAIST. He received his M.S. degree from KAIST in 2010, and his B.S. degree from Inha University in 2008.

Career and Education

Research Interests

Dong-Wan's research interests cover the areas of data mining, databases, big data analytics, computational geometry, and scalable machine learning. Main theme of his research is to develop novel algorithmic tools for speeding up the task of mining a massive volume of data that classic algorithms and conventional computing platforms are hard to analyze. Currently, he is working on making deep learning models more lightweight, continually adaptive, and decentralized for AI-as-a-Service (AIaaS) in resource-constraint devices. For the research, he always pursue his work to be theoretically rigorous as well as practically efficient.

All his works (see publications) can fall into one (or more) of the following topics:
