Full professor at UPF
Research area: Probability / Statistics

PhD in Mathematics obtained at Lancaster University UK (2003)


Omiros Papaspiliopoulos (PhD, Lancaster University, 2003), I am ICREA Research Professor at Universitat Pompeu Fabra and Affiliated Professor at the Barcelona Graduate School of Economics. Previous positions include Research Associate at Lancaster and Oxford University, Assistant Professor at Warwick University, and Professor at UPF.

My research has appeared in the top journals in Statistics, and I have been an Associate Editor for the Journal of the Royal Statistical Society Series B, Biometrika and Statistics and Computing. I have delivered more than 80 invited talks, and have given courses at ENSAE in Paris, the Berlin Mathematical School, the Department of Mathematics at University of Copenhagen, and the Engineering Department at Osaka University. In 2010 I was awarded the Royal Statistical Society’s Guy Medal in Bronze.
