Profile summary

Professional biography

I have joined AstrobiologyOU as a Research Fellow in 2020. 

Prior to that I was a postdoctoral research fellow at the Lunar and Planetary Institute in Houston, USA modelling fluid-rock interactions on Mars and Venus and at the University of Campinas, Brazil, studying melting processes and granitoid formation in the Archean crust. I completed my PhD in Geosciences at th University of Oslo, Norway, modelling density variations in the lower crust and assessing their implications for geodynamic processes.


Research interests

My research covers a range of crustal processes on Earth and other planetary bodies in our Solar system from surface gas-rock interactions on Venus to understanding rock properties of deep crustal rocks and melting processes. Modeling the interaction of fluids with rock compositions in various environments such as in the subsurface of Mars or on Icy Moons is of special interest to explore the possibilities for habitable environments in our Solar System and is therefore my main focus within AstrobiologyOU.
