Jichuan Chang

Biography

Jichuan Chang is a Principal Research Scientist at HP Labs. His research interests are in computer system architecture and memory systems, with a focus on building cost and energy efficient, data centric datacenters. His past research contributions include component-based software reuse, software architecture support for software construction and runtime adaptation, multiprocessor cache coherence and chip multiprocessor caching. His recent contributions leverage emerging technology trends and cross-disciplinary co-designs to improve server efficiency (e.g., low-TCO microBlades, disaggregated memory, and dematerialized datacenter). Dr. Chang received his B.S. and M.S. degrees from Beijing University and his Ph.D. from University of Wisconsin-Madison. He has three papers selected as IEEE Micro's Top Picks.
