Expert has been active in aersol physics for more than 25 years. His PhD covers also the areas of environmental, indoor and cleanroom aerosols.

He worked in a variety of scientific and technical projects covering the health effects of particles to the effects of particles to µelectronic products.

Since he has been working in the field of turn-key design and construction of cleanroom facilities for all applications and cleanliness, the aerosol filtration have been alway s one of the focus points of each and every project.

He has been responsible or working in more than 200 projects in the past decades including all applications like biotech, bio-cleanrooms, pharmacy, semiconductor and nanotechnology industry, medical device, cosmetics and food industries (mostly dairy or steril and aseptic filling).

He published a scientific article about the dynamic effects of aerosol filtration over long term periods on the ICCCS conference in Bonn/Germany in 2004.

He worked as an application manager and sales manager for the American company TSI and installed more than 5 filter scanners for the major aerosol filter companies in the world.

He built (and operated) 4 filter scanners in the past 25 years (starting in 1984) for the inline filter test for the installed filters onsite.
He personally scanned some 10.000 m² of cleanroom ceiling filters.

He is an expert on all kinds of aersol measuring devices like:
- laser particle counters
- impactors
- differential mobility sizers
- aersol spectrometers
- Aerodynamic Particle sizers
- Electrometers
- Photometers
- Off line analysis with TEM, AFM

In the past 2 years Expert consulted two BSL 3 and BSL 4 laboratories in the risk management and compliance with international biosafety standard (UAE and Germany).

Expert has performed GMP compliance audits for two biotechnological active pharmaceutical ingredients facilities with each more than 500 m³ fermenter capacities in Russia.

He consulted with 2 facilities in Romania for the production of APIs in 2004 and 2005. Currently he is lecturer for the GMP aspects of API production and handling. In the moment he is finishing as a chairman a German guideline dealing with separative devices for personnel and product protection including the production and handling of APIs.

Expert has intense knowledge in the qualification and validation of pharmaceutical and medical device manufacturing facilities (more than 100 GMP projects in the past 20 years).

Expert more and more was contacted and is consulting the food industries in the areas of contamination control and certification in the past 5 years. Due to contamination control the due date for sensitive food can be extended up to the factor of 3.

Expert wrote in cooperation with an American colleague the automation system worldwide policy for ROCHE, Switzerland, including the aspects of 21 CFR Part 11 compliance.
He was for the short period of 1 year (2002) a member of the DACH GAMP organization. In addition he has been the external validation supervisor for a big vaccine production MES system in Austria supplied by Emerson Process Management in 2002.

Beside these he has been the European sales manager for cleanroom monitoring systems and has been responsible for the installation and qualification/validation of building control systems, monitoring systems in at least 30 projects over the past 25 years.

Expert intensively worked on the effects of air pollutants onto the cleanroom facilities.

He published his first research results about Clean Air Purifications for the > 64 MB Chip Generations on 12th ICCCS Conference, Yokohama, 1994. The results have been generated by an one year research project together with IBM chip manufacturing facitlity in Germany and former company HOECHST. Mainly airborne molecular contamination have been addressed and the influences from outdoor pollution as well as the filtration aspects investigated.

Today he is the co-chairman for the German AMC cleanroom guideline currently published. As a member of the ISO 14644 German mirror group he supported the internation guideline ISO 14644, part 7, dealing with AMCs.
He worked with all standard measurement devices to measure gaseous pollutants (GC, GC-MS, etc.).

He worked in the development of condesation nuclei counters and the effects of gase to particle conversion process in the outdoor and cleanroom environment.

Pollution and environmental measurements are essential parts of his PHD thesis.
More and more the influences of the outdoor to the indoor cleanroom environments become part of the consulting activites (from semiconductor industries to fertilization) from gases, vapors to living or dead particles.

Expert is currently working in 3 projects for adhesive material as medical devices or as combined products (medical devices + drug -coated plasters with fentanyl) in Germany, Switzerland and Russia.

In addition he is active in the area of Tissue Engineering with Chitosan based structures.

Expert delt with all kinds of filter materials (including PTFE or GoreTex material) in his filter test studies. Some experiments have been performed for the use of this type of filters in the sterile and aseptic filling of food industries.

Expert is currently consulting three companies in the area of antimicrobial medical devices (coating implants or antimicrobial bandages /plasters).

Expert made his degree in physics in thin film coatings of substrates. Due to his activities in semiconductor manufacturing, disc drives, optical data storages and coatings of optical surfaces in the past decades he gained some additional experiences.
He worked for 2 years as the contamination control engineer for Digital Equipment Corporation HDA manufacturing. Here he has been responsible for the cleanliness of the manufacturing environment as well as the cleaning of surfaces, the inspection of surfaces and monitoring of the cleanliness.

Expert has established in the VDI contamination control regulations together with his colleagues the guidelines for contamination control and cleanroom compatibility specification and testing. He currently is consulting and testing around 10 products / manufacturers (partitions, ceilings, equipments, components) per year for product cleanliness requirements.

Expert has been a member of the purified water regulatory guideline group in the 90'. Today he is the moderator for the necessary rework in the guidelines dealing with the today requirements in the pharmacy, semiconductor and other cleanroom industries (VDI 2083, Part 13).
He has been the project manager for various purified water systems of several sizes (his last project for a sterile aseptic pharmaceutical manufacturer): 40 m³/d highly purified water, 280 m³/d WFI, some kilometers of piping, including qualification and validation).

Expert has been dealing with cleanroom garments very often in his expert life:
- as the contamination control manager he tested garments, gloves and other consumables 3 month every year for the evaluation of the compatibility of this material in the production process
- as the member of the VDI 2083, part 4, guideline activities he worked on the specification of the requirements for garments, gloves and other consumables
- he consulted and built 2 cleanroom laundries for garments for bio- and other applications
- today he is training cleanroom personnel and cleanroom operators also in the area of garments and gowning (VDI 2083, Part 15), where he has been the co-chairman in the German guideline activities.
