Bio

Dong Xie is an assistant professor in the computer science and engineering department at Penn State University. He received his Ph.D in Computer Science from University of Utah in 2020, and received his bachelor’s degree from ACM Honored Class of Shanghai Jiao Tong University in 2015. He received the Google Research Scholar Award in 2023, Microsoft Research PhD Fellowship in 2018, and SoCC best paper runner-up in 2019.
His research interest lies in building data systems to address the challenges of processing and analyzing real-world large-scale data. His research span in multiple areas including data systems on modern hardware, distributed databases, main-memory databases, stream processing systems, approximate query processing, spatio-temporal data processing, data privacy, and system security.
