The CompGeoLab is a research group based at the Universidade de São Paulo, Brazil. We are experts in solving inverse problems in the field of Geophysics, particularly in gravity and magnetic methods (AKA potential-field methods). Inverse problems are the means by which geoscientists image the inside of the Earth and other planets. For example, we are able to determine the inner density distribution of the Earth from measured disturbances in the Earth’s gravity field. We are also champions of open science and reproducible research. All of our teaching and research efforts are symbiotic with the development of open source software for geoscience.
