Research group: Groundwater and Hydrogeochemistry
I obtained my diploma in engineering (equivalent to M.Sc.) in the study programe ‘Geotechnical Engineering and Mining’ from TU Bergakademie Freiberg, Germany. Consequently, my main background is in applied rock mechanics and soil mechanics with a focus on the mitigation of geohazards.
In addition, I wrote my diploma thesis in the field of reservoir engineering. Its principal subject related to the numerical modelling of hydromechanically coupled processes in a fractured reservoir at the Geretsried Deep Geothermal Project in Germany.
Since July 2021, I have been working as a PhD student in the GeoREST research project at IDAEA-CSIC. My main field of investigation is the ‘Prediction of Induced Seismicity by the Application of Machine Learning’.

GEoREST (ERC StG)
GEoREST aims at developing a novel methodology to predict and mitigate induced seismicity.
GEoREST aims at developing a novel methodology to predict and mitigate induced seismicity. Fluid injection related to underground resources has become widespread, causing numerous cases of induced seismicity. If felt, induced seismicity has a negative effect on public perception and may jeopardise wellbore stability and infrastructure, which has led to the cancellation of several projects. Therefore, forecasting injection-induced earthquakes is a big challenge that must be overcome to deploy geo-energies to significantly reduce CO2 emissions and thus mitigate climate change and reduce related health issues.
