Title: Toward effective visual analytics for large-scale temporal event data
Speaker: David Gotz, NCDS Data Fellow and Associate Professor of Information Science, UNC-CH School of Information & Library Science
About the Talk: In this talk, Gotz will focus on his research as an NCDS Data Fellow:
Large-scale temporal event data, with vast numbers of long and complex sequences of time-stamped events, are found in a wide range of domains including social networking, security, and healthcare. In the medical domain, for example, electronic health record data with thousands of variables and millions of patients, can be used in comparative effectiveness studies, epidemiological investigations, and patient-centered outcomes research. However, exploratory analysis of this data is often slow, cumbersome, and error prone. This talk will review some of the challenges associated with this form of data and discuss new visual analytics methods being developed by Dr. Gotz to provide practitioners with exploratory analysis tools that are faster, more intuitive, and more reliable.
About the Speaker: David Gotz is an Associate Professor of Information Science in the School of Information and Library Science (SILS) at the University of North Carolina at Chapel Hill. He leads the Visual Analysis and Communications Lab (VACLab), where he conducts research related to the study and development of visual methods for information analysis and communication. He also serves as the Assistant Director for the Carolina Health Informatics Program.Prior to joining SILS, Gotz was a research scientist at the T.J. Watson Research Center at IBM Research. During his final years at IBM, he was part of the Healthcare Systems and Analytics Research Department. He also spent several years working for the Intelligent Information Interaction Department, which he joined immediately after earning his Ph.D. in Computer Science from UNC-Chapel Hill in 2005. Prior to his Ph.D. studies, Gotz received his MS in Computer Science from UNC-Chapel Hill in 2001. He graduated with highest honors from Georgia Tech in 1999, where he majored in Computer Science and received a certificate in Economics.
