Past and Current ResearchIf I had only one line to summarize my past and current research, I would describe myself as a geophysicist focused on measuring, mapping, and understanding the diverse magnetic fields encountered in Earth's environment and in near-Earth-like planets' space. Over the course of my career, I have concentrated on several key areas of research: - Measuring Earth's Magnetic Field: I have been actively involved in global efforts to measure and monitor the Earth's magnetic field, employing a wide range of techniques—from ground-based observations to satellite missions. - Core Magnetic Field and Temporal Variations: A significant part of my work has been dedicated to modeling the Earth's core magnetic field and its temporal variations. I have focused on phenomena like geomagnetic jerks and studied the various contributions to the magnetic field, including those from the lithosphere and external sources like the ionosphere and magnetosphere. - Deep Earth Properties: I have utilized geomagnetic data to infer physical properties of the Earth's deep interior, particularly investigating the conductivity of the lower mantle and the dynamics of fluid motion at the core-mantle boundary. These studies contribute to a better understanding of the processes governing Earth's interior. - Planetary Magnetism: I have long considered that Earth's magnetism should be studied within the broader context of planetary magnetism. This perspective has fueled my interest in the magnetic fields of other planets, such as Mars, Mercury, and Venus, and has guided my research in planetary science and comparative geophysics. - Gravity Fields and Broader Geophysical Studies: While magnetic fields have been the core focus of my research, I have also explored other geophysical domains, particularly gravity fields. This multidisciplinary approach broadens our understanding of planetary interiors and contributes to the wider field of geophysics. Solid Earth and Space Observations: As a geophysicist, I am deeply interested in the use of space-based observation techniques to study the Solid Earth. This encompasses not only magnetic fields but also gravity and other parameters critical to understanding the dynamics of the Earth and other planetary bodies. In my view, science is more than just a profession—it's a passion and a hobby that must be shared with others. I have always sought to pass on my knowledge, guiding students through internships and PhD projects, many of whom have gone on to successful careers. I take great pride in their achievements and enjoy continuing to engage with them as colleagues and collaborators in the field of geophysics. Moreover, I believe it is our duty as scientists to contribute to the well-being of the scientific community. Throughout my career, I have been involved in a variety of activities aimed at advancing the field of geophysics and supporting the broader scientific community, whether through public outreach, collaboration, or service in scientific organizations.
