About me

I am a PhD student in Computer Science Department at UCLA. I am affiliated with Networked and Embedded Systems Lab (NESL) where I work under the supervision of Prof. Mani Srivastava. I received my M.S. degree in Computer Science and Informaion Engineering from National Taiwan University, where I had actively been working in Communications and Multimedia Laboratory directed by Professor Jia-Lin Wu, IEEE fellow. During that time, I was focusing on research areas of Multimedia System, Video Content Analysis, and Digital Signal Processing. I received my B.S. degree in Computer Science from National Chiao Tung University, where I was working in areas of Mobile Networks and Voice over IP (VoIP); I was co-advised by Professor Meng-Hsun Tsai and Professor Yi-Bin Lin, IEEE fellow.

Before I joined NESL, I was a protocol software engineer Mediatek Inc., the 2nd largest mobile phone chip maker. Prior to Mediatek, I was a firmware engineer in IBM Taiwan System and Technology Laboratory (which is acquired by Lenovo in 2014).

I love building systems and solving problems regarding computer networks, software systems, and various applications on mobile devices, including topics on context-aware systems, cloud computing and privacy, machine learning, wireless networks, and Named Data Networking (NDN).

Professional Summary

Before UCLA, I was a protocol software engineer at a fast-paced IC design company for 3+ years, and I served as a firmware engineer for 1+ years. In summer 2016, I worked as a Technical Intern in Synopsys, the leading in electronic design automation (EDA) and semiconductor IP company. I developed low-level APIs using C/C++ in Linux environment to read device memory and estimate power consumption of programs/instructions; this feature will be included in the next release of their EDA tool.
