Zhengji Zhao is a member of the Advanced Technologies Group at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. She has nearly 20 years of experience in high-performance computing (HPC), with a broad portfolio that includes supporting materials science and chemistry applications, participating in system procurements, developing workload analysis tools, and porting applications to many-core and GPU-based systems. She has led the development of checkpoint/restart standards for HPC production workloads and specializes in power and energy analsyis and modeling to improve data center operational efficiency. She has authored more than 40 publications in these areas. Zhengji holds a Ph.D. in computational physics from New York University.
