Alexandre Rothan

• Responsible for product quality and throughput of 8 production lines - Improved first pass yield from 99.4% to 99.7% over 4 years and 5 products - Achieved 100% timely closure of quality deviations and CAPAs across production unit • Preparation and support for client audits - Zero major findings in 4 client audits and 3 ISO audit • Served as internal SME supporting project managers • Frequent contact with clients regarding deliverables, and specification revisions • Optimizing process parameters to decrease costs and increase volumes and reliability - Delivered CHF 300k/year OpEx savings (4% of the energy and raw material budget) through process optimization • Drafting of SOPs for production instructions and analytical methods for production operators • Providing material, process, and safety-related training for shift colleagues • Monitoring in-process analyses, identifying trends, and troubleshooting issues - OEE increase from 96% to 98%, through optimized process parameters and standardized SOP • Since 01/2024: deputy Head of Production, with 36 FTE • SAP production super-user / point of contact

• Development and production of poly alkyl methacrylate-based oil additives • Project coordination regarding new raw material approval and lab to plant upscaling • Troubleshooting and manufacturing process improvement for the production units • Management of a team of 2 senior technicians

• Installation of a production unit for high-performance ceramic • Outsourcing and coordination of structural analysis (X-ray diffraction, Neutron diffraction) • Conducted a chemical risk assessment, and implemented measures to improve coworker safety

• Provided a solution, based on bibliographic review, to produce thermally and electrically insulating polymer thin films, for infra-red sensor applications • Prepared the resulting experimental R&D project: feasibility evaluation, research of suppliers and subcontractor, quote and provisional schedule preparation

• Title: “Rheological study of thermoset formulations, for the modelling of moulding processes like Sheet Moulding Compound” • Scientific publication: “Unusual time dependent rheological behaviour of a concentrated suspension” DOI: 10.3933/ApplRheol-27-64182 • Optimized a Sheet Moulding Compound formulation to tune its mechanical and thermal properties, as well as its reactivity. • Used various analytical methods to characterize the above-named properties. • Acquired a wide knowledge of the different processing ways of thermosetting resins and composite materials. • Co-ordinated the activities of suppliers, sub-contractors, and multiple industrial partners. • Supervised an undergraduate intern and master students during practical work.

Development of multi-layer printed organic photovoltaic cells. -Improved the adhesion between the upper hydrophilic layer on top of the lower hydrophobic layer, in order to upscale the photovoltaic cell production by allowing the use of ink-jet printing. -Plasma treatment -Ink formulation
