Aufried studied Applied physics at the HTS in Enschede from 1980 till 1984 and received his degree in 1984. His first internship was at Delft university Developing a measurement method to determine the gas residence time in a mixed gas-liquid system. The second internship was at KEMA institute in Arnhem developing/testing a SF6-gas leak detection system. The third internship was at the HTS Enschede working on developing a PID-controlled water heating system used as test setup for practical lessons.


From 1984-1986 ; As Research Technician at the Low Temperature division at the University of Twente developing a horizontal-feed-through cryostat with a vibrational isolated but temperature conduction cooling mechanism. It is presented as a chapter in a thesis.

From 1986-1988 ; As Process Engineer at STORK-Ketels in Hengelo, developing Software for thermal boiler performance calculations, thermal boiler performance calculations for customers and participation in a development team for new boiler types.

From 1988-now ; As Research Technician, first at the BioPhysical Engineering group BPE and later the Medical Cell BioPhysics group MCBP. Supported the development of new techniques and developed instruments on several research areas such as; SPR-sensors, waveguide sensors, Single Molecule Microscopy and Raman Spectral Microscopy. Beside this a important part of the work is also guidance of students and PhD’s inside the projects.

From 2008-now he is running an company TWENSPEC in which the main activities are the development of prototype instruments. For instance the developed and manufacturing of 6 Blood Waste Collection Devices used within the CTC-project has been an recent assignment for Twenspec.
