Hello! I am a third year Ph.D. student in the Department of Computer Science & Engineering at University of Washington.
I am currently working with Prof. David Wetherall and Prof. Arvind Krishnamurthy, and also collaborating with Dr. Jaeyeon Jung (MSR), and Dr. Matthai Philipose (MSR).
Prior to joing UW, I worked as a software engineer at NHN Corp. for three and half years. Before then, I
got my B.S. and M.S. degrees from KAIST.
From Apr.~Jul., I'm interning at Telefonica I+D in Barcelona, Spain!

Research Interests
My research interests are primarily in mobile computing and networked systems.
It spans topics like computer networking, operating systems, mobile services, privacy and security.
Recently, I have worked on various project in mobile systems (e.g.,
natural language interface for third-party mobile applications[
hotmobile-demo13]
studying and providing solutions for smartphone privacy
issues[
spsm12,
nsdi-poster12,
ccs11].
Also, I've been involved in a project for creating a new Internet architecture with censorship resistant property[
hotnets11].
Prior to studying in UW, I participated in various research projects, such as GPU-accelerated SSL[nsdi11],
and online social network analysis[www07].
