Dr. Joyce SchmatzDr. Joyce Schmatz

Geologist | Managing Director

Joyce Schmatz heads Research & Service Innovation and is managing director at MaP – Microstructure and Pores GmbH, Aachen, Germany. As a geologist holding a PhD in Structural Geology from RWTH Aachen University, in the last decade her research was focused on rock-fluid interaction in the Earth’s upper crust, aiming to characterize the physical properties of rocks and pore fluids and their role in flow and transport mechanisms in porous and polycrystalline rocks. Schmatz proved the existence of asperity pinning effects in two-phase fluid flow interactions between brine and enclosed oil droplets via high-resolution Cryo-SEM imaging and continues to contribute to a better understanding of mass transfer and transport processes to improve predictions on the long-term stability of nuclear waste repositories and to better understand two-phase flow properties in subsurface reservoirs. More recently her work inside MaP has extended beyond geological applications of these technologies into material, health and life-sciences, pushing the boundaries on what is possible to achieve in microstructural imaging and analysis with technology available today.

Dr. Jop Klaver

Geologist | Managing Director

Jop Klaver is managing director of MaP – Microstructure and Pores GmbH. After finishing a BSc degree in civil engineering with specialization in geotechnology he started a joint MSc degree in geology at the VU University Amsterdam in the Netherlands and Bergen University in Norway. He obtained a PhD at the RWTH Aachen University on the pore space characterization of organic-rich shales using Broad Ion Beam milling and Scanning Electron Microscopy (BIB-SEM). In the frame of his PhD project he developed an integrated multiscale imaging workflow by using BIB-SEM mapping and quantitative analyses resulting in highly cited papers related to the pore space morphology and microstructure of Posidonia, Haynesville and Bossier shales. He subsequently further developed the liquid metal injection method for assessing the 3D pore connectivity via 2D BIB-SEM mapping of metal injected rocks as alternative to 3D methods. His main research interests are quantitative imaging of tight rocks for the evaluation of porosity and permeability data in porous media.

Mingze Jiang, MSc.

Software Engineer

Mingze Jiang is an image processing specialist and software developer at MaP – Microstructure and Pores GmbH, Aachen, Germany. He is currently working on microstructures and pore analysis for various project and different materials using image processing techniques, such as pore segmentation and classification based on Secondary Electron Images, as well as mineral segmentation and classification based on Backscattered Electron Images and EDS data, or ViP (Virtual Petrography) optical microscopy. He holds a M.Sc. degree in electrical engineering from University of Aachen. Before he finished his study, he worked as an intern at Bosch GmbH, where he was involved in developing an object recognition system for monitoring different scenarios. During this time, he deepened his knowledge in the field of deep learning and image processing.
