Staff profile

Gustavo is an Assistant Professor in X-Ray Computed Tomography with Environmental Applications in the Department of Engineering at Durham University, where he is a member of the SMART (Soil Microbiome Augmentation and Restoration Technologies) Soils team. He obtained Engineering Diplomas in Mechanical Engineering and Civil Engineering from Universidad de los Andes (Colombia) in 2017, followed by an MSc in Geotechnical Engineering in 2019 from the same institution. He completed his PhD in 2022 at Université Grenoble Alpes (France). His research career has focused on the mechanics of materials, with particular emphasis on advanced material characterisation using X-ray Computed Tomography (XCT). He has worked at the European Synchrotron Radiation Facility, gaining extensive experience in XCT imaging across a broad range of materials. Since 2019, he has also been a core developer of the open-source spam software, a Python-based tool for quantitative analysis of 2D images and 3D volumes for mechanics applications built around X-ray and neutron tomography.
