Keun Soo Yim leads an Android systems testing project at Google, Inc as a technical lead and engineering manager. He started his career as an embedded software developer in 1999 (using a 32-bit DSP and code mostly written in assembly code). He continued his kernel work at Samsung Research (in Korea) where he developed multiple real-time operating system (RTOS) kernels and tools for consumer electronic devices. Part of his such works (about flash memory management) was presented at Ottawa Linux Symposium (OLS) in 2008. He then obtained his Ph.D. degree in Computer Science from the University of Illinois at Urbana-Champaign (UIUC) based on his works on characterizing and detecting soft errors in CPU-GPU hybrid super computers. Currently, he is a member of the Android platform engineering department at Google, Inc and is actively developing and launching various software engineering services and tools for the Linux kernel communities and Android platform ecosystem. He believes that every one should be given the opportunities to not only build kernel, but also use open source tools to test and ship kernel.
