Cornelius Stefan Rampf

Dr. Cornelius Stefan Rampf is a theoretical cosmologist currently serving as Permanent Staff (equivalent to Assistant Professor) at the Division of Theoretical Physics, Ruđer Bošković Institute in Zagreb, Croatia since February 2024. Previously, he held postdoctoral positions at the University of Vienna (2021-2024), Observatoire de la Côte d'Azur in Nice as a Marie Skłodowska-Curie Fellow (2018-2021), University of Heidelberg as a DFG Research Fellow (2016-2018), and several other prestigious institutions including the Technion, University of Portsmouth, Albert Einstein Institute, and University of New South Wales.

Dr. Rampf earned his PhD in Theoretical Physics from RWTH Aachen University in Germany (2010-2013, magna cum laude) and completed his Diploma in Theoretical Physics at the University of Karlsruhe/KIT (2004-2009, magna cum laude). His research focuses on the fluid dynamical aspects of cosmic large-scale structure formation, with particular expertise in perturbation theory, asymptotic methods, numerical simulation techniques, and general relativity applications in cosmology.

His research interests encompass cosmic structure formation, perturbation theory for cosmological fluids, shell-crossings and singularities in cosmic structure evolution, numerical simulation techniques for cosmological structure formation, and the application of general relativity to large-scale structure modeling. Dr. Rampf has made significant contributions to understanding gravitational collapse as a critical phenomenon, developing fast and accurate N-body simulation techniques, and modeling massive neutrinos with high accuracy in cosmological contexts.

Dr. Rampf's publication record shows a consistent focus on theoretical cosmology with recent work emphasizing the intersection of fluid dynamics, numerical methods, and cosmological structure formation. His most recent papers demonstrate increasing sophistication in handling non-linear effects, singularities, and relativistic aspects of cosmic structure formation. The publications reveal a trajectory from foundational work on perturbation theory toward more complex modeling of cosmic evolution, with growing emphasis on computational efficiency and accuracy.

Dr. Rampf actively supervises multiple graduate students across institutions in Zagreb and Vienna, including master's and PhD candidates. He has secured significant third-party funding including a highly competitive Marie Curie Fellowship and multiple DFG research grants. As Scientific Coordinator of the TRR33 "The Dark Universe" collaborative research center, he managed a substantial budget of 12.5 million euros and implemented effective gender equality initiatives that significantly improved resource utilization for female researchers. Dr. Rampf is also a prolific reviewer for numerous prestigious journals and research organizations, and regularly organizes international conferences and winter schools on cosmology.

Dr. Rampf is a co-organizer of the annual Winter School on Cosmology in Passo del Tonale (Italy) and has organized multiple international workshops including the upcoming "Putting the Cosmic Large-scale Structure on the Map" conference in Vienna (2025) and the "Cosmology in the Adriatic" workshop in Split, Croatia (2024). He maintains active research collaborations across Europe and internationally, with frequent seminar presentations at leading institutions worldwide.
