Measure, Probability and Functional Analysis

Hannah Geiss is a Senior Lecturer of Mathematics at the University of Jyväskylä (Finland), where she has been employed since 2001. She obtained her PhD at the Friedrich Schiller University Jena (Germany). From 2010 to 2014, she served as an Assistant and Associate Professor at the University of Innsbruck (Austria). Her research interests lie in stochastic analysis and stochastic processes.Stefan Geiss is a Professor of Mathematics at the University of Jyväskylä (Finland). He obtained his PhD and habilitation from the Friedrich Schiller University Jena (Germany). After research stays at the University of Paris 6 (as a Marie Curie Fellow) and the Technical University of Vienna (Austria), he accepted a professorship at the University of Jyväskylä in 2000. From 2009 to 2014, he held a professorship at the University of Innsbruck before returning to Jyväskylä. Stefan Geiss’s research focuses on probability and functional analysis, with a particular emphasis on the interconnections between the two fields.
