Biography:
Dr. Jaime Arguello teaches courses and conducts research in the areas of information retrieval, data mining, and machine learning. His main area of research is aggregated search, where the goal is to develop search systems that integrate results from multiple independent sources. Dr. Arguello develops algorithms and evaluation methodologies for deciding which sources to select and how to display them. His most recent research studies how users interact with aggregated search displays and how differences in display affect users’ expectations and behaviors.
Dr. Arguello’s second main area of research focuses on search assistance, where the goal is to develop interactions to help search engine users working on complex tasks. This research aims to understand when and how people employ search assistance. The ultimate goal is to develop systems that automatically provide assistance at the right times and in the appropriate ways.
Dr. Arguello holds a Ph.D. in Computer Science from Carnegie Mellon University. He publishes regularly at information retrieval venues such as SIGIR, ECIR, CIKM, and IIIX.  He was a recipient of the SIGIR 2009 Best Paper Award and the ECIR 2011 Best Student Paper Award, and was awarded the NSF CAREER Award in 2015.
