Dr. Yosuke Yamazaki
Space and Atmospheric Physicist, Freelancer for Leomagnetics
Freelancer for Leomagnetics and our top expert in data analysis. Studies in-situ space environment observations from low-earth-orbiting satellites (wind, density, temperature, plasma parameters) and magnetometer data from ground and space. Prolific scientist (ORCiD). PhD from Kyushu University, Japan. Worked at NCAR, US, Lancaster University, UK, GFZ, Germany and now at IAP Kühlungsborn.
P.D. Dr. Alexander Grayver
Geophysicist and Computational Scientist, Freelancer for Leomagnetics
Geophysicist with expertise in high-performance computing, geomagnetic and electromagnetic modeling, ML-based data analysis and inverse problems (ORCID). Programs in C++ and Python. Works at the University of Cologne, carrying out independent research and teaching on topics related to geophysical imaging, geothermal exploration, and geomagnetic field modelling using ground and space observations. In the past, he held research positions at GFZ Potsdam and ETH Zurich.
M. Sc. Marcos Vinicius Siqueira da Silva
Geophysicst, Programmer and Data Specialist, Freelancer for Leomagnetics

We promote Sustainability
Downstream Sustainability
Space activities provide means to improve life on our planet. With our know-how on the space environment we can help keeping space clean, orbits sustainable and satellites alive.
Geomagnetic surveying methods are used to find minerals and metals. These are key materials that drive the energy transition. Geomagnetism is one of our core competences.
Upstream Sustainability
As a lean company, we have a small footprint. Wind energy fuels our virtual servers and their heat is not wasted, but used. We are enthusiastic about our new photovoltaic system and favor environmental friendly means of transportation. As often, less is more.
As a company with a global approach, we see merit in engaging with local and regional suppliers all over the world. We believe in talent and in empowering people everywhere on our planet.
