Professor of Computer Science
Jamie Callan is a Professor at the Language Technologies Institute in the School of Computer Science, with a joint appointment in the Heinz College's School of Information Systems & Management. Prior to joining Carnegie Mellon, he was a Research Assistant Professor at the University of Massachusetts, Amherst, and worked for seven years as a software engineer for Digital Equipment Corp. Callan received his BA in Applications of Computer Science at the University of Connecticut, his MS in Computer and Information Science from the University of Massachusetts, and his PhD in Computer Science from the University of Massachusetts.
Callan's research and teaching focus on text-based information retrieval and analysis. His recent research studies advanced search engine architectures, federated search of groups of search engines, adaptive information filtering, and text analysis, organization, and mining. He has published more than 150 research papers on these subjects.
Callan participates regularly on the program committees of conferences such as SIGIR, CIKM, WSDM, and ECIR. He has been a Program Chair of the CIKM and SIGIR conferences, and has co-organized a variety of workshops. He has served on the editorial boards of several information retrieval journals, and is currently the Editor-in-Chief of ACM Transactions on Information Systems. He is a past Treasurer (1999-2003) and Chair (2003-2007) of ACM SIGIR.

For more than a decade, Professor Callan has been co-PI of the Lemur Project, which creates and distributes open-source search engine software, search tools, and datasets that are used by a broad international research community. Each year dozens of the scientific papers published in leading conferences and journals describe research done using resources created by the Lemur Project.
