Peter K. Friz studied in Vienna, Paris and Trinity College, Cambridge, before earning his PhD (2000–2003) at NYU's Courant Institute under the supervision of S.R.S. Varadhan. After holding positions at Merrill Lynch and Cambridge University, he moved to Berlin in 2009, where he is presently Einstein Professor at TU and WIAS Berlin. He works in stochastic/rough analysis and quantitative finance. Wolfgang König received his PhD at the University of Zurich in 1994. After holding postdoc positions in the Netherlands, the UK and Canada, and an assistant professor position at TU Berlin, he spent five years in Leipzig as a professor. In 2009 he moved back to Berlin to accept a joint position as professor at TU Berlin and head of a research group at WIAS. He works on applied probability, large deviations and statistical mechanics.  Chiranjib Mukherjee obtained his PhD in Mathematics at the Max Planck Institute Leipzig and the University of Leipzig in2011. After holding postdoc positions in Erlangen, Munich and Berlin, he was a visiting assistant professor at the Courant Institute, NYU, where he collaborated with S.R.S. Varadhan. Since April 2017 he has been an assistant professor of mathematics, specialising in probability theory, at the University of Münster, Germany. His research interests lie in stochastic analysis, PDEs and applications to statistical mechanics.  Stefano Olla earned his PhD at Rutgers University (1987) under the direction of Joel Lebowitz and was a postdoc at the Courant Institute, where he collaborated with S.R.S. Varadhan. After holding positions in Rome, Torino and Cergy-Pontoise, he has been a professor at the Université Paris Dauphine-PSL since 2002. He works in non-equilibrium statistical mechanics and hydrodynamic limits.
