Evrim Acar is a Senior Research Scientist at Simula Research Laboratory. Her research interests are data mining
and mathematical modeling; in particular, tensor decompositions, data fusion using coupled factorizations of higher-order tensors and matrices, and their applications
in social network analysis, computational neuroscience, metabolomics and chemometrics. Evrim has also been with the Chemometrics and Analytical Technology group at the University of Copenhagen,
Denmark since March 2011. She was a recipient of the Danish Council for Independent Research Sapere Aude Elite Young Researcher Award in 2012.
Evrim received her MS and PhD in Computer Science from Rensselaer Polytechnic Institute (Troy, NY)
in December 2006 and May 2008. She got her BS in Computer Engineering from Bogazici University
(Istanbul, Turkey) in July 2003. (see
