-Managed day-to-day operations of a biological safety lab, ensuring reliable workflows and safe compliance with lab procedures. -Conducted research using custom bioreactor setups and designed experiments to evaluate the effect of mechanical stimulation on biological samples. -Supported teaching activities in Mechanics I–III (exercise sessions, student support, grading).

-Maintained and supported an R package (PhysioSpace), including documentation and workflow upkeep. -Explored RNA-seq and single-cell datasets within the PhysioSpace framework to support robust data analysis pipelines.

-Performed sterile cell culture and routine cell counting; prepared collagen-based hydrogel samples. -Executed Live/Dead staining and microscopy imaging; supported quantitative image analysis (ImageJ/Fiji). -Conducted compression testing on hydrogel samples and documented test conditions/results for reproducibility.

-Produced magnetoresponsive microgels using the PRINT method and supported iterative optimization of fabrication parameters. -Performed biofunctionalization (e.g., RGD peptides, fibronectin fragments) to tailor material–cell interactions.

-Selected and quoted technical solutions based on customer requirements and project specifications. -Created budget calculations and supported planners with technical alternatives aligned with available product portfolios. -Followed up on quotations and coordinated with internal stakeholders to ensure feasibility and timely responses.

-Supported mechanical site supervision on an industrial plant project; coordinated daily execution with contractors and client representatives. -Oversaw welding and piping activities, tracked progress, and produced daily technical reports. -Participated in coordination meetings to align work plans, safety, and quality expectations.

-Supported offer preparation and product homologation activities within the Low Voltage and Products business unit. -Developed virtual configuration tools in Excel/VBA to streamline internal workflows and improve efficiency. -Assisted cross-functional teams (sales/marketing/technical) and supported event organization.

-Conducted inspection, installation, troubleshooting, and maintenance of medical equipment in customer environments. -Supported device software management (updates/configuration) and provided technical support to internal teams. -Tracked corrective maintenance cases and ensured structured follow-up and reporting for service quality.

-Supported course delivery through workshop facilitation, student support, and structured feedback. -Evaluated and graded assignments and workshops according to course standards.

-Supported process documentation for planning and transport management workflows. -Monitored operational planning tools (EnRuta) and supported coordination of pipeline transport nomination/planning activities.

Master’s thesis: Development and construction of a bioreactor for mechanical stimulation of vocal fold samples through stretching and vibration, including mechanical system development, Python-based control and image analysis.
