Cathal Gurrin is an Associate Professor at the School of Computing, at Dublin City University, Ireland and he is a co-investigator at the Insight Centre for Data Analytics and the Adapt Centre where he leads a research group of 10 people. His research interest is personal analytics and lifelogging (a search engine for the self). He is especially interested in how wearable sensors can be used to infer knowledge about the real-world activities of the individual and how such sensor data can be used to enhance the performance and health of the individual. He has developed WWW search algorithms, multimedia content mining tools and he has gathered a digital memory since 2006 (incl. over 15 million wearable camera images) and hundreds of millions of other sensor readings. He regularly speaks at Quantified Self events and is the author of Lifelogging: Personal Big Data, published in 2014 in the FNTIR series.
