Personal profile
Academic background
• 2023, Assistant Professor, Applied Geophysics | Department of Geoscience and Engineering, Delft University of Technology, Delft, The Netherlands.
• 2016-2023, Research Associate, Institute for Geophysics | Department of Physics, University of Münster, Münster, Germany.
• 2010-2015, PhD Geophysics | Department of Physics, University of Alberta, Edmonton, Canada.
• 2005-2010, BSc Astrophysics | University of Alberta, Edmonton, Canada.
Research profile
• Expertise: Applied Electromagnetic Geophysics and Quantitative Interpretation of Data.
• Primarily engaged in acquiring and applying electromagnetic geophysical data to answer questions related to volcanic and geothermal regions, mineral systems, and tectonics -- at various scales and with the integration of other geoscientific data.
Research interests
• Mapping and understanding the plumbing and sources of volcanic and geothermal systems, at both shallow and deep scales.
• Investigating the deep sources of mineral systems, their crustal-scale footprints, and their links to major crustal boundaries.
• Applying joint inversion schemes to geophysical data to extract new model constraints and new quantitative interpretations.
• Examination and modelling of extreme magnetotelluric data potentially caused by high-contrast conductive anomalies and current channeling effects in features of interest.
• Using thermo-mechanical modelling to explore the dynamics and evolution of the lithosphere with the integration of electromagnetic models and derived viscosity/rheology constraints.
• Electrical structure of the upper-crust to the whole-lithosphere and implications for tectonic evolution (including faulting, suturing, and mountain-building), crust-mantle interactions, and geodynamics.
