Research Interests

The research is aiming at the correlation between atomic structure and observed optical properties.
New chiral substances are synthesized as models for structure-feature studies, for example from adding chiral ligands to Isothyocyanates. These new substances crystallize well and allow a multitude of variations of their chemistry while being strongly structurally related.


New optical measurement techniques are developed to collect data on chiroptical properties like optical rotation, Faraday Effect, circular dichroism, the electro-optic effect, and electrogyration. Such new methods allow to measure optical rotation in any transparent crystal,  to simultaneously detect transmission, retardation and extinction angles of heterogeneous materials (millipol), and to image circular extinction in solids.


Semi-empirical models are developed to be applied to the visible spectral range of light which allow calculating electrogyration, the electro-optic effect and the d-coefficients for frequency doubling, using the atomic structure and empirical polarizability volumes for the individual atoms.


X-ray structure determination and chemical analysis as part of the duties for the UW Department of Chemistry complement these studies.


I devoted some of my time to the development of software packages to aid the teaching of physical crystallography. This resulted in one program for the presentation of tensorial features in form of representation surfaces (WinTensor for Windows) and another program for the presentation of crystal morphology as virtual reality models (WinXMorph for Windows).
