GTT-Technologies is a truly international company with people working from all around the world.
- Prof. Dr. Klaus Hack
Dr. Klaus Hack graduated in Physics from RWTH Aachen, Germany. He started working in thermochemistry while undertaking research for his diploma (high temperature mass spectrometry on ternary alloys) and continued in this field with his doctoral work (adiabatic high temperature calorimetry on ternary alloys). During his postdoctoral work at National Physical Laboratory, UK, he carried out assessments of boron-metal systems and also developed software for the assessment and calculation of binary and higher order substitutional solution properties.
- Dr. Ernst Münstermann
Dr. Ernst Münstermann graduated in Physics from RWTH Aachen University, Germany. He started his research work in experimental thermochemistry (thermogravimetry, emf measurements, high temperature mass spectrometry). For many years he was Oberingenieur at the department of Theoretical Metallurgy (later: Materials Chemistry) of RWTH Aachen University. He joined our company in 2011 as Managing Director.
- Dr. Gunnar Eriksson
Dr. Gunnar Eriksson is the developer of the successful thermochemical application software programs, ChemSage, and its equally renowned predecessor SOLGASMIX. He graduated in Chemistry at Umeå University, where his main interest was the development of software programs for the calculation of complex multiphase, multicomponent equilibria. He has published about 50 scientific papers in this and related fields. He has worked mainly in Canada and Germany; and for shorter periods, in the USA, England, Australia and Japan.
- Ursula Haese
Mrs. Ursula Haese is the executive signatory of GTT. She handles all administrative work in the company.
- Dr. Jürgen Korb
Dr. Jürgen Korb graduated in Metallurgy at Bergakaddemie Freiberg. He did research on single crystal silicon growth in industry prior to returning to akademie to perform scientific research on semiconductor materials and pyro metallurgical processes. He recieved his Ph.D. in 1977, and has authored 14 scientific publications. He joined GTT-technologies in 1991.
- Dr. Stephan Petersen
Dr. Stephan Petersen graduated in Materials Science at the RWTH Aachen in 1989. He subsequently joined the institute of Solid State Physics at Research Centre, Jülich, where he worked on highpressure solution growth and defect thermochemistry of gallium-arsenide. This formed the basis for his Ph.D. degree, which he recieved in 1994. He joined GTT-Technologies in 1992.
- Dr. Tatjana Jantzen
Dr. Tatjana Jantzen graduated in Physics at the Ural Polytechnic Institute, Ekaterinburg, Russland. She started to work in thermochemistry 1995 at the Department for Theoretical Metallurgy, RWTH Aachen, in the working group of Dr. P. Spencer. In 2002 she joined GTT-Technologies. Her professional area is the modeling of phases, thermodynamic evaluations of metallic and slagsystems, and creating of databases.
- Wajahat Murtuza Khan (M.Sc.)
Mr. Wajahat M. Khan obtained his Bachelors degee in Computers Science Engineering from Osmania University in Hyderabad, India. After working as an IT specialist in India he moved to Germany and graduated with a Masters degree in Software Systems Engineering from RWTH Aachen with a specialization in Artificial Intelligence, Informations Systems & Databases and wrote his Master thesis in the area of High Performance Computing. Prior to joining GTT-Technologies, he had worked on various R&D projects at the University and was a project engineer at DLR - The German Aerospace Research Center.
- Dipl. -Math. (SU) Lioudmila Greven
Mrs. Lioudmila Greven studied applied mathematics at the Tomsk Polytechnic University, Russia. She worked as a developer of algorithms and software programs, also implemented and serviced system software and databases at the Project Institute of Oil and Gas in Yekaterinburg, Russia. In 2007 she joined GTT-Technologies.
