About

I’m a Space Engineer specialising in spacecraft thermal systems, currently contributing to the NewATHENA Wide Field Imager (WFI) at the Max Planck Institute for Extraterrestrial Physics. My work lies at the intersection of engineering precision and scientific exploration — ensuring that space instruments like WFI operate flawlessly in some of the most extreme thermal environments imaginable. Over the past few years, I’ve built a diverse portfolio across thermal design, propulsion, and nanosatellite systems, working with organisations such as DLR and GomSpace. From optimising cryogenic turbopump performance to developing nanosatellite thermal models and thermal test procedures, I’ve learned how to translate scientific challenges into engineering performance. Core Competencies: - Space Thermal Control & Subsystem Integration - Thermal Modelling, Correlation & Testing (ESATAN TMS, TVAC testing) - Rocket Turbopump and associated Fluid Systems Design and Testing - Multidisciplinary Collaboration & Supervision I’m passionate about enabling space exploration through system-level thinking and strong collaboration, and I’m now looking to broaden my perspective towards thermal systems engineering and systems engineering for space in general — connecting multiple domains to build resilient, efficient spacecraft architectures.
