Read here about my research interests; download papers and preprints:
- Mandelbrot set, matings, and complex dynamics. See also the videos.
- Scattering theory and quantum mechanics.
- Fracture mechanics and composite materials.
2005–2006 I was a teacher-in-training at the Erasmus-von-Rotterdam Gymnasium in Viersen, Germany. On Friday afternoons there was a study group on the Mandelbrot set with my former 11th-grade students.
Since 2007 I am teaching mathematics and physics at Gesamtschule Brand, a community college for grades 5–13, located in Aachen, Germany. We use ucloud4schools and Padlet, Logineo and Strato.
See our attempt at K-Pop, and a video explaining the matrix modeling a stochastic process (in German).
Binomial 2.2 is a program for illustrating the binomial probability distribution and its approximation by a Gaussian, and for calculations related to testing of hypotheses. The latest release is available here. Exercise sheets are included in the German version.
Processwork (or Process Oriented Psychology) is a method of awareness training with various applications in psychotherapy and facilitation. Look here for a brief introduction. I have done various trainings in Portland Oregon, Zurich, Stuttgart, and Wuppertal. In 2022 I have completed the basic training and the phase-I exams at Institut für Prozessarbeit Deutschland to enter the diploma training.
