Stokesian Particle Dynamics for microrheology applications between chemistry and engineering

Hans Fraaije

Chief Science Advisor

Siemens, Netherlands

Dr. Fraaije started his industrial career in the mathematics research department of Akzo chemical company in the Netherlands in the late 1980s. At that time, while working on a paint application, he invented the ‘Mesodyn’ for predicting mesoscale patterns in polymer blends; the algorithm has been distributed commercially since 1997. Since 2000, Dr. Fraaije is a professor at Leiden University, where he started Culgi computational chemistry company in 2004. In 2020, Siemens acquired Culgi; Culgi is now part of the Simcenter portfolio of solutions in the process industries. Dr. Fraaije currently serves as Chief Science Advisor within Siemens’ industrial software division (DI SW) and is on leave from Leiden University. Dr. Fraaije has been working in industrial computational chemistry throughout his career, in triple capacity: as an inventor, entrepreneur, and as a professor.
