Doctoral ResearcherMax Planck Institute Of Colloids And Interfaces Jun 2021 - May 2024Potsdam, Brandenburg, AllemagneI led a research project delving onto the drying process of mesoporous ceramic gels (silica aerogels) using dynamic X-ray imaging methods (μCT) combined with automated 3D image processing and data analysis (Python, Dragonfly, Excel, Origin). By correlating the evolution of the materials composition with the evaporation models in porous materials, I aim at understanding the drying process to improve the manufacturing of aerogels.• Thesis: "Kinetics of reversible deformations during the evaporative drying of silica aerogels".• Led all aspects of a research project.• Planned and conducted experiments worth 75'000+ euros.• Chemical synthesis and self-assembly of silica nanoparticles.• Designed, executed and validated a semi-automated method to generate composition maps of gels during drying with an 11 μm resolution using X-ray micro-computed tomography (μCT).• Collaborated in 3 interdisciplinary projects to leverage evaporation mechanisms, image processing and data analysis.• Mentored 2 bachelor and master students.• Published 3 peer-reviewed articles in top-tier journals and participated to 2 international conferences in 3 years.• Analyzed over 4 TB of data in Python. -
Simulation EngineerEmpa Aug 2020 - Mar 2021St. Gallen, SwitzerlandI Conducted 100+ simulations on the cooling of fresh fruits upon cargo transport to monitor and predict fruits shelf-life. This work built the premises of a new deliverable for the stakeholders to assist their customers on when and where food quality is lost in their supply chains.• Enhanced the computation time from 100 h to 20 min in a very short timeframe by implementing a porous media airflow approach.• Academic-industrial collaboration with a large multinational sensor company.• Heat transfer and fluid dynamics modeling using finite element method (FEM).• Proficiency with the software Comsol Multiphysics®.• Data analysis and statistical analysis using VBA in Excel.• Co-author on 1+ publication in top-tier journals. -
Research And Development AssistantHeidelbergcement Feb 2020 - Jul 2020Heidelberg, GermanyI was responsible for the testing of cementitious materials to quantify their mechanical properties and microstructure upon enforced carbonation (carbon sequestration).• Optimized a multi-methods experimental workflow that boosted operation efficiency by 50%.• Supervised technicians on the implementation of the procedure.• Contributed the project initiation phase for the production of carbon-neutral concrete by 2050. -
Municipal EmployeeCommune De Sainte-Croix Sep 2018 - Dec 2019Sainte-Croix, Vaud, SwitzerlandResponsible assistant at the municipal waste collection center during weekends and holidays.• Guided and sensitized the public on the disposal of solid waste. • Recognized for my communication skills and diplomatic attitude. -
Research AssistantEpfl (École Polytechnique Fédérale De Lausanne) Jul 2019 - Aug 2019Lausanne, Vaud, SwitzerlandI evaluated and modeled the binding process of chlorides in 30+ cement pastes to understand and predict the concrete lifetime against chloride attack.• Presented the findings of our group at the international conference Microdurability 2020.• Proficiency with materials characterization methods: XRD, SEM, TGA, titration.• Co-author of 1 publication in a top-tier journal. -
Retail CashierDenner Ag Apr 2014 - Jul 2018Sainte-Croix, Vaud, SwitzerlandI worked as a cashier during the weekends and holidays for over 4 years to help finance my studies.• Skills acquired: neat organization of items on a shelf, how to keep calm with impatient customers, spotting thieves.
