Wim De Pauw received a Ph.D. degree in computer science from the University of Ghent, Belgium, in 1991. At the Watson Research Center he has been a research staff member since 1992 and has led the software visualization projects Ovation (C++ visualization), Jinsight (Java visualization), Web Services Navigator (visualizing Web Services), Streamsight (visualization of streaming data), Zinsight (visualization of complex logs), FLEXsight (visualizing MapReduce jobs), DUCCsight (visualizing Watson DeepQA jobs) and analysis of events from logs. Most of these research projects have been transferred into IBM products, were offered as free tools on IBM alphaWorks, or have contributed to open source projects. Dr. De Pauw's current responsibility is to invent visualization tools for complex IT systems, such as service-oriented architectures, large streaming data applications and log analytics on Big Data. His scientific interests include addressing large horizontal complexities in systems by using visualization, pattern extraction, and adaptive tracing techniques. He has published articles in refereed journals, has chaired conferences, and holds several patents in software visualization, tracing and debugging.
