Johan Lambert Trudo Maria Bollen (born 1971) is a Belgian scientist currently investigating Meme diffusion, the relation between social media and science, markets and sentiment and metrics from usage data. He presently works as associate professor at the Indiana University School of Informatics and Computing. He is best known for correlating Twitter mood to stock market prices, although with controversies of data mining bias.[2] He has taught courses on data mining, information retrieval and digital libraries. His research has been funded by The Andrew W. Mellon Foundation, National Science Foundation, Library of Congress, National Aeronautics and Space Administration and the Los Alamos National Laboratory.
Biography
Bollen received his MS in Experimental Psychology from the Free University of Brussels in 1993 after a master thesis "Learning to Select Activities: a Conditionable System for an Autonomous Robot that Learns to Use Drive Reduction as Reinforcement."[3] He defended his Ph.D. in psychology from the Free University of Brussels in October 2001 on the subject of cognitive models of human hypertext navigation.[4] From 2002 to 2005 he was an Assistant Professor at the Department of Computer Science of Old Dominion University. He was a Staff Scientist at the Los Alamos National Laboratory from 2005-2009. He is currently an Associate Professor at the Indiana University School of Informatics and Computing.
Work
As a result on his work on predicting the stock market based on Twitter mood, Derwent Capital Markets started the Absolute Return fund, the worlds's first Twitter hedge fund.[5] However, it later shut down after thirteen months.[6]
