Research

My main research interests comprise Early Earth evolution including Earth processes (tectonics, geodynamics) and deformation of Earth (supercycles). I am currently a PI in two international initiatives. One is focused on trying to understand Earth evolution in deep-time and the emergence of life, and the other involves Fingerprinting Earth resources with innovative next generation plate reconstructions, using paleomagnetism and potential field data for 4D reconstructions, as well as machine learning with topical big data science.

My collaborative multidisciplinary research is also addressing applied research topics like the use of magnetic minerals as an environmental proxy on different timescales, impact of anthropogenic activities on environment, and the role of magnetic particles in human health (i.e., geohealth).
