Frank joined COSMOlogic GmbH & Co KG (now Solvation Chemistry, a part of the BIOVIA brand of Dassault Systèmes) when the company was founded in 1999. He wrote most of the COSMOtherm code and is involved in the scientific development, quality management and maintenance of what are now the BIOVIA Solvation Chemistry program packages. Over the years, he has specialized in chemical engineering thermodynamics, including process modelling & CAPE-OPEN, and physicochemical properties. Frank is also an expert for the intersections of molecular modelling, quantum chemistry, and thermodynamics, for example in the modeling of reaction mechanisms and pKa calculation.
