Hello! I've recently completed my Ph.D. in Computer Science & Engineering at the University of Washington. I am moving to California soon to join Rubrik, Inc., an exciting startup building data protection systems.

At UW CSE, I worked with three awesome advisors, Prof. Thomas Anderson, Prof. David Wetherall and Prof. Arvind Krishnamurthy, and also closely collaborated with Dr. Matthai Philipose (MSR). Prior to joining UW, I worked as a software engineer at Naver Corp. for three and half years. Before then, I received my B.S. and M.S. degrees from KAIST.
