FZ is developed by researchers from the University of Chicago, Indiana University, Florida State University, and Ohio State University. We work together with researcher all over the world to build the most advanced lossy compression library.
Principal Investigators
Franck Cappello is the director of the Joint-Laboratory on Extreme Scale Computing gathering six of the leading high-performance computing institutions in the world. He is a senior computer scientist at Argonne National Laboratory and an adjunct associate professor in the Department of Computer Science at the University of Illinois at Urbana-Champaign. He is an expert in resilience and fault tolerance for scientific computing and data analytics. Recently he started investigating lossy compression for scientific datasets to respond to the pressing needs of scientist performing large-scale simulations and experiments. His contribution to this domain is one of the best lossy compressors for scientific datasets respecting user-set error bounds. He is a member of the editorial board of the IEEE Transactions on Parallel and Distributed Computing and of the ACM HPDC and IEEE CCGRID steering committees. He is a fellow of the IEEE.
Dr. Sheng Di is a computer scientist at Argonne National Laboratory, USA. He received his Ph.D degree from The University of Hong Kong. He is an IEEE senior member. He is a scientist at Large through the Consortium for Advanced Science and Engineering (CASE) at the University of Chicago, and also an institute fellow of Northwestern-Argonne Institute of Science and Engineering (NAISE). Dr. Di's research interests include high performance computing, distributed computing, cloud computing, lossy compression, fault tolerance, etc. Dr. Di published 150+ papers in prestigious conferences and journals, including SC, ICS, HPDC, PPoPP, ICDCS, VLDB, ICDE, DSN, IPDPS, etc. He is the DOE 2021 Early Career Research Program Award Winner, and also the recipient of 2018 IEEE Chicago Section Distinguished Mentoring Award and 2019 IEEE Chicago Section Distinguished Research and Development Award. Dr. Di is the winner of the 2019 R&D100 award and 2021 R&D100 award.
Fengguang Song is an Associate Professor of Computer Engineering in the Luddy School of Informatics, Computing, and Engineering at Indiana University Bloomington. He earned his Ph.D. in Computer Science from University of Tennessee at Knoxville under the direction of the 2021 Turing Award Winner, Jack Dongarra. After receiving his PhD, he continued to work with Jack as a Post-doctoral Research Associate between 2010 and 2012, then worked as a Senior Research Scientist in the Computer Science Lab at Samsung Research America-Silicon Valley. Between 2013 and 2023, Dr. Song worked as an Assistant Professor then Associate Professor of Computer Science at Indiana University Purdue University.
Dr. Kai Zhao is a tenure-track assistant professor in the Department of Computer Science at Florida State University. He received his Ph.D. from University of California, Riverside in 2022 and his B.S. from Peking University in 2014. He received the Dean’s Distinguished Fellowship (2017), the Dissertation Year Program Fellowship (2021), and the Laxmi N. Bhuyan Fellowship (2021) from University of California, Riverside. His research interests include scientific data management, reduction, and analytics, and fault-tolerant computing. He is one of the key developers and researchers of the SZ lossy compression software which won the 2021 R&D 100 Award. He has published more than 20 papers in prestigious conferences and journals, including SC, HPDC, PPoPP, VLDB, ICDE, ACM ICS, PACT, and TPDS.
Dr. Hanqi Guo is an Associate Professor at the Department of Computer Science and Engineering at The Ohio State University, and he also holds a joint appointment at the Mathematics and Computer Science Division at Argonne National Laboratory. His research interests include visualization, analysis, and machine learning for large-scale scientific data. He is an awardee of the Department of Energy (DOE) Early Career Research Program (ECRP) in 2022 and received multiple best paper awards in premiere visualization conferences.
Post-Doctoral Researchers
Robert Underwood is a Post Doctoral Appointee in the Mathematics and Computer Science Division at Argonne National Laboratory focusing on using data compression to accelerate I/O for large-scale scientific applications including AI for Science. His library LibPressio, which allows users to experiment and adopt advanced compressors quickly, has over 200 average unique monthly downloads, is used in over 17 institutions worldwide, and is a contributor to the R&D100 winning SZ family of compressors and other compression libraries. He regularly mentors students and is the early career ambassador for Argonne to the Joint Laboratory for Extreme Scale Computing.
