APPROACH

From micrometers to kilometers

Synthesized iron mineral suspension in the laboratory

Geochemistry on the bench

In the lab, I synthesize iron minerals to reconstruct environmental conditions on ancient Mars.

NASA's Perseverance rover on Mars

Robotic field geology

With rover data, I investigate Martian rocks up close, bridging the lab bench and the view from orbit.

ESA Trace Gas Orbiter above Mars

Mapping habitability from orbit

With ESA and NASA orbiters, we map water-rich minerals, tracing where Mars was once habitable.

Water frost on Martian mountaintops

Evidence for transient morning water frost deposits on the Tharsis volcanoes of Mars

With the TGO/CaSSIS team, we discovered morning water frost on the solar system's tallest volcanoes — where it was thought impossible. The finding made the cover of Nature Geoscience.

Properties of Phobos and Deimos

With the CaSSIS camera on ESA's Trace Gas Orbiter, we imaged Mars' two small moons in colour and tracked how their brightness and colour change with viewing angle — clues to what their surfaces are made of.

Is the Moon still geologically active?

I mapped young tectonic features and surprisingly young-looking surfaces in the lunar maria to test whether the Moon's nearside is still active today.
