Xunfei Jiang Defends and Heads to Earlham College

Xunfei Jiang

In summer 2014, Xunfei Jiang successfully defended her dissertation. Currently, Dr. Jiang is an Assistant Professor of Computer Science at Earlham College, IN.

Dr. Jiang received her Ph.D. degrees during the Auburn University commencement ceremony held in August 2014 (see a photo here).

Xunfei Jiang received the BS. and M.S. degrees in Computer Science from Huazhong University of Science and Technology(HUST), China, in 2004 and 2007. Then she joined Digital Video Networks Co., Ltd. in 2007 and Cisco Systems (Shanghai) Video Technology Co., Ltd in 2010. She received her Ph.D. degree in the Department of Computer Science and Software Engineering, at Auburn University in 2014. Her research interests include Parrallel and Distributed System, Energy-Efficient Storage Systems, Thermal Modeling, Thermal-Aware Task Scheduling and Data Placement, and Hybrid Data Storage Systems.

In the past few years, Dr. Jiang has been working on several projects related to thermal-aware resource management in data centers. In her dissertation study, she investigated the thermal impact of storage systems. In the first phase of Dr. Jiang's research, she generated the thermal profile of a storage server containing three hard disks. The profiling results show that disks have comparable thermal impacts as processing and networking elements to overall storage node temperature. She developed a thermal model to estimate the outlet temperature of a storage server based on processor and disk utilizations. The thermal model was validated against data acquired by an infrared thermometer as well as build-in temperature sensors on disks. Dr. Jiang also applied the thermal model to investigate the thermal impact of workload management on storage systems.
