Brief Autobiography
Dr. Yuan-Hao Chang (IEEE Fellow)
Dr. Yuan-Hao Chang (Johnson Chang) received his Ph.D. degree in Computer Science from National Taiwan University, Taipei, Taiwan in 2009. He is currently a Deputy Director and Research Fellow (Professor) of Institute of Information Science (IIS), Academia Sinica. He is also a Jointly Appointed Professor of National Taiwan University (NTU), Taipei, Taiwan and an Honorary Distinguished Professor of National Taiwan Normal University (NTNU), Taipei, Taiwan. Previously, he served as an Associate Research Fellow between Mar. 2015 and Jun. 2018 and Assistant Research Fellow between Aug. 2011 and Mar. 2015.
His research interests include Computer System, Computer Architecture, Embedded System, Operating System, Memory System, Storage System, and Non-volatile Memory.
Publications
Dr. Chang has published more than 100 research papers in top journals (including 50+ in premier ACM/IEEE Transactions, e.g., IEEE TETC, IEEE TC, IEEE TCAD, IEEE TVLSI, IEEE TIFS, ACM TECS, ACM TODAES, and ACM TOS) and top conferences (including 50+ in USENIX OSDI, ACM/IEEE MICRO, ACM/IEEE DAC, ACM/IEEE ICCAD, ACM/IEEE ISLPED, ACM/IEEE CODES+ISSS, ACM/IEEE EMSOFT, ACM/IEEE CASES, IEEE RTSS, IEEE RTAS, and IEEE ISSCC). He has also been granted for dozens of US and Taiwan patents.
Among these papers, he has published more than 25 papers in ACM/IEEE DAC, which is the #1 out of the 102 conferences listed in the Hardware and Architecture Domain of the Microsoft Academic Search. In addition, he has published two USNIX OSDI papers (OSDI'20 and OSDI'23), where OSDI is one of the two best venues in the fields of computer systems and operating systems. These are the only two OSDI papers solely contributed by Taiwanese teams over the past 30 years (1995-2024). He also published a paper in ACM/IEEE MICRO'22, one of the top three computer architecture conferences, where Taiwanese teams have published fewer than five papers in the past 30 years (1995-2024).
