Probability & Statistics Group Heidelberg-Mannheim

Peter received his diploma in Mathematics from the University of Heidelberg (in topological dynamics supervised by Prof. Wolfgang Krieger). He completed his PhD in Mathematics at the Saarland University in 2013 (in stochastic analysis supervised by Prof. Christian Bender). He joined the research group in 2012 and is working on:

  • Stochastic analysis

Helmut is a member of RTG1953 since August 2018.

He received his diploma in Mathematics from the University of Tübingen in 2012. He completed his PhD in Statistics at the Oxford University (2013-2015), was Assistant Professor at UC Berkeley (2015-2017) and Postdoc at TU Dresden (2017-2018).His research interests lie in probability theory and its applications as well as statistics. The problems he considers are motivated by questions arising in mathematical population genetics, statistical physics, and computer science. These questions often fit into the more general topic of large-scale limits of random combinatorial structures. More specifically, they include:

  • limit theorems in probability,
  • random trees and stochastic processes,
  • coalescent processes.

Philip received both B.Sc. (2013) and M.Sc. (2016) in Business Mathematics from the University Mannheim. During his studies he specialized in probability theory ans statistics. Since 2016 Philip is a PhD Student at the University of Mannheim where he is working on stochastic processes. His research focuses on Lévy processes and self-similar Markov processes, especially their relation through the Lamperti transformation. He defended hit thesis "Lévy processes conditioned to avoid and hit intervals" on December 17th, 2018 and continues with his work as a Postdoc in RTG.
