Hobin Yoon is a Ph.D. student in the College of Computing at the Georgia Institute of Technology, advised by Dr. Karsten Schwan. Prior to joining Georgia Tech, he was a Senior Researcher at Samsung Electronics from 2005 to 2010 and a Senior Engineer at Thinkware Systems from 2001 to 2005. He earned his BS and MS in Computer Engineering from Seoul National University. Hobin's research interests center on operating systems and distributed systems. He is currently exploring cloud storage management systems with virtualization technology.

My research interests center around distributed systems, storage systems, and operating systems.

Current research project is providing an efficient multi-datacenter storage management system by analyzing and configuring applications’ data consistency/urgency requirements and optimizing their inter-datacenter communication. The research targets globally distributed applications such as Facebook or Google’s services. The storage system includes distributed key-value stores such as Apache Cassandra and object stores. As an experimental test bed, I am running a storage cluster, where each of the participating nodes is virtualized by Xen hypervisor and grouped by data centers with realistic inter-data center network packet delays among them. It provides Amazon EC2-like environment with more control on the underlying platform.
