David Gleich, professor of computer science in the College of Science and University Faculty Scholar, has been named to the Class of 2025 Fellows of the Society for Industrial and Applied Mathematics (SIAM). He is recognized for his research contributions to matrix-based network analysis and his contributions to the foundations of higher-order network analysis.
His work in the Department of Computer Science focuses on developing novel models and fast large-scale algorithms that advance scientific data analysis, bioinformatics, and network analysis. His research has transformed the way scientists analyze complex datasets, using innovative computational methods to extract insights from massive networks, matrices, and tensors.
"His pioneering work in network analysis and numerical linear algebra has pushed the boundaries of data-driven scientific computing. From studying brain networks to optimizing jet engine noise, his research has had a profound interdisciplinary impact. His widely used software packages, with tens of thousands of downloads, have empowered researchers across disciplines,” said Petros Drineas, professor and head of the Department of Computer Science.
He added, “David's innovative approaches to large-scale, complex data analysis continue to shape the future of computing, and we are proud to celebrate his achievements at Purdue CS and beyond."
One of Gleich’s areas of expertise is Google’s PageRank algorithm and how it is used in diverse areas across science from biology, chemistry, and physics to engineering such as traffic monitoring.
Beyond theoretical advancements, enabling researchers worldwide to efficiently process large-scale graph and network data. His work has been supported by the National Science Foundation (NSF), the Department of Energy (DOE), the Defense Advanced Research Projects Agency (DARPA), the Intelligence Advanced Research Projects Activity (IARPA), and NASA.
Gleich received the SIAM Outstanding Publication Prize (2018), a Sloan Research Fellowship (2016), and an NSF CAREER Award (2011). Before joining Purdue, he was awarded the prestigious John von Neumann postdoctoral fellowship at Sandia National Laboratories, where he further developed his expertise in large-scale scientific computing. His selection as a SIAM Fellow reflects both his technical contributions and his leadership within the scientific computing and applied mathematics communities.
About the Society for Industrial and Applied Mathematics (SIAM)
Society for Industrial and Applied Mathematics (SIAM) is an international community of 14,000 individual members. Almost 500 academic, manufacturing, research and development, service and consulting organizations, government, and military organizations worldwide are institutional members. SIAM was incorporated in 1952 as a nonprofit organization to convey useful mathematical knowledge to other professionals who could implement mathematical theory for practical, industrial, or scientific use.
About the Department of Computer Science
Founded in 1962, the Department of Computer Science was created to be an innovative base of knowledge in the emerging field of computing as the first degree-awarding program in the United States. The department continues to advance the computer science industry through research. Graduates of the program are able to solve complex and challenging problems in many fields. The increasing centrality of computer science in academic disciplines and society, and new research activities - centered around data science, artificial intelligence, programming languages, theoretical computer science, machine learning, and cybersecurity - are the future focus of the department.
