The people behind MTEX

Ralf Hielscher

Founder and lead developer

Invented MTEX in 2007 by implementing the algorithm that turns pole figures into an ODF, and has led its development since then.

Institute of Applied Analysis, TU Bergakademie Freiberg

Rüdiger Kilian

EBSD and grains

Joined MTEX in 2008 as a PhD student of Renée Heilbronner in Basel. He has answered hundreds of questions in the forum and keeps improving the EBSD and grain analysis of MTEX.

Martin-Luther-Universität Halle-Wittenberg

David Mainprice

Tensors and seismic properties

Joined MTEX in 2009 by sharing his code for tensor properties and seismic velocities, and has brought MTEX to the geoscience community ever since.

Géosciences Montpellier, France

Luiz Fernando Grafulha Morales

Physical properties, support and workshops

A structural geologist, electron microscopist and long-time MTEX user. He helps with physical properties, user support and the workshops.

ScopeM, ETH Zürich, Switzerland

Florian Bachmann

Grain reconstruction

Started with MTEX in his diploma thesis at TU Freiberg in 2008, where he implemented the grain reconstruction. He also built the import wizard and the documentation centre.

Xnovo Technology ApS, Denmark

Bjørn Eske Sørensen

Spectral diffraction and birefringence

Contributes to spectral diffraction and birefringence.

Department of Geoscience and Petroleum, NTNU, Norway

Tuomo Nyyssönen

Parent grain reconstruction

Worked on parent austenite reconstruction during his PhD at Tampere University of Technology, and wrote the first MTEX code for reconstructing parent grains and determining the orientation relationship.

SKF, Netherlands

Frank Niessen

Orientation relationships

Generalised the orientation relationship analysis and parent grain reconstruction to arbitrary phase combinations, and wrote the export to ctf and ang files.

Xnovo Technology ApS, Denmark

Vivian Tong

TrueEBSD

Uses MTEX to study plastic deformation in engineering materials. She developed TrueEBSD, the image registration for correlative microscopy, and contributed many features and fixes.

University of Birmingham, UK

Azdiar Gazder

Orientation relationships

Worked on the orientation relationship analysis and parent grain reconstruction for arbitrary phase combinations. Co-developer of the ORTools and phaseSegmenter toolboxes and author of mtexTools.

Electron Microscopy Centre, University of Wollongong

Felix Bartel

Spherical functions

Wrote the classes of spherical functions during his master's thesis at TU Chemnitz in 2019.

Scientific Computing, Catholic University of Eichstätt-Ingolstadt

Erik Wünsche

Functions on the rotation group

Wrote the classes of functions on the rotation group during his PhD at TU Freiberg.

TU Bergakademie Freiberg

Tim Pöschl

Function approximation

Works on the approximation of orientational and directional functions, in particular by moving least squares.

Oliver Kent Johnson

Misorientation colour key

Implemented the misorientation colour key. He finished his PhD in 2015 with Christopher A. Schuh at MIT.
