Consultancy & Support on Microbial Protection of Products and Manufacturing Processes- Analysis and Evaluation of Biocide Systems (existing & alternative)- Safe & Legally Compliant Application of Biocide Systems- Expertise in Product Formulation and Manufacturing Process Optimization- Assessment of Plant Hygiene

• The heritage Microbial Control Business was integrated into Lanxess MPP (Material Protection Products).
• Technical Support to our tollers re. upscaling, production, special tests, reworks, cleaning procedures, product wheel, compatibility of materials of construction, optimisation of processes with the aim of production.
• Technical Support to internal groups such as quality assurance, product development & formulation, distribution, Regulatory etc. e.g. for special batch releases (quality waivers), raw material qualification, stability.
• Managing the technical know-how of our business unit, including the drafting of comprehensive technical product documentation (technology packages).Achievements:
• Saving substiantial amounts of money each year alone by guidance through complex reworks of failed batches (instead of material disposal).
• Critical Support enabling the successful transfer of production to a new toller.

• The heritage Microbial Control Business was acquired by IFF.
• Technical Support to our tollers re. upscaling, production, reworks and root cause analysis of failed batches, special tests, cleaning procedures to minimize risk of cross contamination, optimisation of processes with.
• Technical Support to internal groups such as quality assurance, product development & formulation, distribution, Regulatory etc., e.g. for special batch releases (quality waivers), raw material qualification, stability.
• Critical technical support enabling the successful transfer of production of entire product portfolio from internal site to an external toller.
• Saving substantial amounts of money each year alone by guidance through complex reworks of failed batches (instead of material disposal).

• Dow Microbial Control was acquired by DuPont.
• Formulation: Development and stabilisation of liquid and pasty biocidal formulations for microbial control (bacteria, yeast, fungi, algae) in finished products for all kinds of applications, e.g. for household and.
• Hands-on execution of stability studies, material compatibility testing (e.g. w.r.t. corrosion) and phys.-chem. analyses incl. HPLCAchievements:
• guided the successful development and characterisation of 2 product formulations.

• The former Acima Business was integrated into Dow Microbial Control.
• Formulation: Development and stabilisation of liquid and pasty biocidal formulations for microbial control (bacteria, yeast, fungi, algae) in finished products for all kinds of applications, e.g. for household and.
• Stability studies, material compatibility testing (e.g. w.r.t. corrosion) and phys.-chem. analyses incl. HPLC
• Screening and identification of synergistic biocide combinations with/without booster with the help of an automated screening equipment (robot). and comprehensive patent analysis in the area of in-can preservation.
• Raw material evaluation and Technical Support to production (upscaling, reworks), quality assurance etc.Achievements
• managed the development and characterisation of 12+ formulated products commercialized successfully

Buchs, St Gallen, Switzerland

• Acima AG was acquired by Dow in 2009.I was supervisor of 3 lab technicians in the R&D lab.Similar job activities as in the sections described above (2013-2022).Achievements:
• managed the development and characterisation of 13+ formulated products commercialized successfully
• achieved 4 granted patents

• Development and stabilisation of liquid or lyophilised pharmaceutical preparations of active ingredients for parenteral administration, e.g. as blood substitute and/or for maintaining the human immune system.
• Thermal analysis (TA) and use of differential calorimetry (DSC) for the determination of the glass transition temperature of protein preparations as basis for the optimisation of lyophilisation processes.
• Evaluation of primary packaging containers for their suitability for aseptic filling and packaging of pharmaceutical products under GMP.Achievements:
• Implemented the Thermal Analysis / DSC equipment platform in the R&D lab as basis for developing lyophilisation processes most efficiently.
• Identified the primary packaging material with most robust performance in the aseptic filling process out of a selection of materials.

Buchs, St Gallen, Switzerland

• I worked for the heritage Fluka Chemie AG that was acquired by Sigma-Aldrich around 1993.I was the Technical Service Manager as of 1996, supervising 3 technical assistants (2 part-time).
• I supported the international clientele and subsidiaries in German, English and French in the use of Fluka chemicals (> 20'000).
• I used the inputs from my group's customer contacts to make suggestions to the marketing department regarding product range extensions.
• I compiled technical product information from suppliers, dealt with customer complaints and was the interface to the laboratory.Achievements:
• Each year I proposed dozens of chemicals and analytical kits that were subsequently selected for the annual product range extension campaign.
• Supported our product management in OEM projects with customers (incl. visits) using our fluorescent dyes as chemical component. (OEM: Original Equipment Manufacturer)
