Aus aktuellem Anlaß

Verschiedene deutsche wissenschaftliche Institutionen haben beschlossen, alle Kooperationen mit russischen Institutionen und/oder Wissenschaftlern einzustellen, sowohl laufende als auch zukünftige. Dazu folgender Kommentar:

  1. Russische Wissenschaftler setzen sich zu Tausenden privat und öffentlich für ein Ende des Angriffs auf die Ukraine ein, teils unter Gefahren für Leib und Leben, die wir uns in Deutschland kaum ausmalen können. Diesen Menschen sollten wir helfen und nicht zusätzlich schaden.

  2. Sowohl ein Ende der Aufnahme russischer Wissenschaftler in Deutschland als auch die Einstellung von Kooperationen vergrößert Leid, statt es zu mindern, und hat keinerlei tatsächlichen Nutzen. Ein solcher Ansatz erscheint mir voraufklärerisch und inhuman.

Der oben angesprochen Boykott ergibt nicht nur keinen Sinn, er ist auch moralisch rückständig. Ich distanziere mich ausdrücklich davon.

Upcoming Dates

  • My talk to high-school pupils on Mathematics in Electronic Music, originally scheduled for April 23rd, 2020, has been cancelled. I’ve replaced it with a streamed concert on that day; please see this page for details. We’re trying to find a date to realize the original event in 2022.

News

Research

I am developing numerical techniques for accurate and efficient computer simulations. A particular focus is on scalable algorithms that run on the largest supercomputers worldwide. A cornerstone of this research is the p4est software that I am lead-authoring.

Some geophysical applications are listed below.

  • Thermal convection (a.k.a. plate tectonics)
  • Seismic wave propagation (a.k.a. earthquakes)
  • Hyperbolic conservation laws (a.k.a. atmospheric flow)

The mathematical methods considered relate to the following fields.

  • Scientific computing and applied mathematics
  • Large scale parallel numerical solution of PDEs
  • Scalable algorithms for adaptive mesh refinement

Please see more details on my research pages. Check out my profile on Google Scholar and on the arXiv.
