I have experience working at the intersection of engineering, customer success, and technical documentation, with a focus on helping customers adopt complex products successfully. In my most recent role, I delivered more than 100 customer demonstrations and technical training sessions, supported sales efforts, and handled remote and onsite technical support. I also closed around 250 support tickets annually and contributed to product quality by diagnosing, repairing, and testing acoustic gas leak sensors. I have owned end-to-end customer-facing technical documentation and multilingual manuals, and I have onboarded and trained about 50 new employees. I enjoy translating technical complexity into clear, practical guidance for users, teams, and stakeholders. Before that, I worked as a doctoral scientist at EPFL, where I conducted experimental research on water molecules and gas-surface interactions using advanced spectroscopy and ultra-high-vacuum systems. This experience strengthened my analytical thinking, experimental rigor, and ability to work on technically demanding problems. I hold a Ph.D. in Chemistry and Chemical Engineering, along with a Masters and Bachelors in Chemistry. My academic and professional path has given me a strong foundation in scientific communication, problem-solving, and cross-functional collaboration. I am open to opportunities where I can combine technical expertise, customer engagement, documentation, and product support. I bring an international perspective, multilingual communication skills, and a strong commitment to delivering value to both customers and teams. ## Skills 13 capabilities[Cross Functional Collaboration](https://jobicy.com/talent/cross-functional-collaboration.md)[Customer Success](https://jobicy.com/talent/customer-success.md)[Customer Training](https://jobicy.com/talent/customer-training.md)[Experimental Design](https://jobicy.com/talent/experimental-design.md)[Gas Systems](https://jobicy.com/talent/gas-systems.md)[Multilingual Communication](https://jobicy.com/talent/multilingual-communication.md)[Onboarding](https://jobicy.com/talent/onboarding.md)[Problem Solving](https://jobicy.com/talent/problem-solving.md)[Product Support](https://jobicy.com/talent/product-support.md)[Research](https://jobicy.com/talent/research.md)[Sales Support](https://jobicy.com/talent/sales-support.md)[Technical Documentation](https://jobicy.com/talent/technical-documentation.md)[Technical Support](https://jobicy.com/talent/technical-support.md) ## Experience Career history ### Senior Field Application and Customer Success Engineer · Distran AG Jan 2023 – Jan 2025Delivered customer demonstrations and technical training, supported sales, handled remote and onsite technical support, closed support tickets, maintained technical documentation and multilingual manuals, onboarded new employees, and coordinated user feedback for product development. ### Doctoral Scientist · EPFL Jan 2018 – Jan 2023Conducted experimental research on water molecules and gas-surface interactions, built and maintained gas systems, authored scientific papers, and presented findings at international conferences. ## Education Learning history ### Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland Jan 2018 – Jan 2023Ph.D., Chemistry and Chemical Engineering Doctoral studies in chemistry and chemical engineering with research at EPFL and the Max Planck Institute for Solid State Research. ### University of St Andrews, Scotland Jan 2013 – Jan 2018Masters and Bachelors, Chemistry Completed integrated masters and bachelors studies in chemistry.
