Moved!

Since June 2016, I am with the EE department at KAIST as a postdoctoral scholar, working with Prof. Changho Suh. This page is not maintained anymore, and please visit my new web page.

Short Bio

I received my PhD in May 2016 from the Electrical Engineering and Computer Science department at UC Berkeley and my Master of Science degree from the same department in December 2012, both under the supervision of Prof. Kannan Ramchandran. I was a member of Berkeley Laboratory of Information and System Sciences (BLISS, aka Wireless Foundation) and BASiCS Group. I received my Bachelor of Science degree in Electrical Engineering from Korea Advanced Institute of Science and Technology (KAIST) in May 2010.
