My research investigates how the solar system formed and evolved by studying the composition of extraterrestrial materials. I’m especially interested in volatile elements and organics—the building blocks of life as we know it. In the lab, I employ a range of high-tech tools, including noble gas mass spectrometry, Raman spectroscopy, NanoSIMS, and Scanning Electron Microscopy (SEM).
Currently, my PhD student and I are focused on studying extraterrestrial dust particles. These tiny grains, expelled from comets and asteroids during collisions and outgassing, are the most pristine solar system materials we can access. Virtually unmodified since their parent bodies formed some 4.6 billion years ago, they give an exciting glimpse into the infancy of our solar system. We want to understand what these building blocks of the solar system look like, and we are investigating whether dust particles could have delivered life-essential volatile elements and organics to the early Earth.
However, perfect samples are hard to come by. The dust grains heat up when they collide with Earth's atmosphere, altering their original state. To understand how heating affects our samples, we conduct experiments. Another fun challenge is their tiny size—comparable to the width of a human hair! This requires us to develop special handling methods and use high-sensitivity tools to analyze them. But the hard work pays off because these samples are truly one-of-a-kind!
The upcoming Lunar Gateway space station which will orbit the Moon is a unique opportunity to study extraterrestrial dust in a clean environment. I'm a part of ESA's Facility Definition Team for dust science on the Lunar Gateway space station, where I help prioritize scientific exploration objectives and define essential measurements to fulfil those objectives.
A few years ago, I had the privilege of being part of the early analysis team in JAXA's sample return mission to asteroid Ryugu. Together with my colleagues, I analyzed noble gases in bulk material, container gases, and macromolecular organic matter. This mission was a unique opportunity to study samples that had never been exposed to Earth's atmosphere. Unlike meteorites, which always have some degree of terrestrial alteration and whose parent asteroids are usually unknown, sample return missions provide us with untainted samples and precise origins.
Beyond my research, I’m enthusiastic about improving management and leadership in academia. I've earned a Project Management Professional (PMP) certificate, which has helped me develop an agile project management approach suitable for experimental research. Currently, I’m pursuing a Master of Advanced Studies in Management, Technology, and Economics at ETH.
