Research Interests:
Geologist who codes
I try to understand the fault mechanics in rifts by considering the faults as a network that evolves.
Originally a field and structural geologist by background, I have learnt programming during my various experiences and enjoy using it to develop innovative techniques to understand geodynamic processes. Developer of Fatbox, the fault analysis toolbox. I am also very interested in analogue modelling to recreate earth processes in a sandbox and see millions of years of evolution in live.
I like to share science and marvel at the beauty of the Earth.
Career:
Doctoral researcher in GFZ since January 2023
Mapping and analysis of fault networks evolution in continental rifts using digital elevation map, image processing and machine learning techniques.
