I have lived and worked in six countries on three continents,
Germany, the USA, Japan, Austria, Czechia and Sweden.
My personal interests are astronomy, chess and travel.
My professional interests are mathematics, physics
and macromolecular crystallography..
My favorite programming language by far is Python.
Currently I work mostly on research in special relativity,
quantum mechanics and nonlinear time series and nonlinear
partial differential equations.
Most of my professional career I spent as a research scientist
in academic and industrial research in the field
of protein crystallography, covering experimental, theoretical
and computational aspects of the field. My most important contribution
was to the development and first succeessful application of a technology
called multi-wavelength anomalous diffraction. It is now the default
method for new structures. My postdoctoral work involved the
first successful application of the method in 1987.
Cauchy Integral Formula
$$\Large{f(a) = \frac{1}{2\,\pi\,i}\,\oint_\gamma\,\frac{f(z)}{z - a}\,dz}$$
