Wei Zhang (张威) is currently a Postdoctoral Researcher in Scientific Data Management Group at Lawrence Berkeley National Laboratory (LBNL), USA. He received his Ph.D. degree from Texas Tech University in 2021. His research interests generally lies in the intersection of high performance computing (HPC) and big data management. Specifically, his research areas include metadata search and querying, graph data management, geospatial data analytics, and storage resource management. Before joining LBNL, he had many years of industrial experiences working for some of the prominent large scale distributed storage systems, including the storage system of Weibo.com (the Chinese version of Twitter) as well as the Big Data Service of Oracle Cloud Infrastructure.
