Dieter Mueller | Vacuum Science World

Dieter Müller


After obtaining his M.Sc. Physics degree from Technical University Darmstadt, Germany, Dieter has deepened his knowledge in low temperature and solid-state physics at the University of Hamburg. Dieter worked for Leybold in Cologne for more than 35 years. In the last 7 years he was responsible for the analytical instruments market and since 2016 in the Scientific Vacuum Division of Atlas Copco Vacuum Technique.

Dieter is currently a deputy manager of the training committee of the German Vacuum Society DVG and for several years was a member of the board of the DVG. Dieter retired from Leybold in 2018, now working as a consultant for Atlas Copco‘s Scientific Vacuum Division. He is also lecturer for vacuum applications at the University of Applied Sciences in Giessen, Germany.


Peter Lambertz | Vacuum Science World

Peter Lambertz


After graduating in Environmental Process Engineering at the RWTH Aachen University and in Industrial Engineering at the Fernuni Hagen, Peter gained his first professional experience in Project Management and Team Leader functions in Research and Industry.

He has been working in the vacuum industry in different Marketing and Business Development related functions for more than 10 years, with a special focus on vacuum solutions for research and scientific applications for Leybold, Edwards and Gamma Vacuum.  He is now Business Line manager for the Scientific Business of the Leybold Europe South Customer Centre.

In November 2018 Peter was invited to be an active Vacuum Science World contributor, and to share his knowledge and experience with our visitors.


Andrew Chew | Vacuum Science World

Dr Andrew Chew

GLOBAL Applications Manager

After completing a PhD in Vacuum Physics at the York University (UK), Andrew held a post-doctoral fellowship there collaborating with the KFZ in Karlsruhe investigating a New technique for the measurement of the intrinsic drag torques of high temperature superconductor bearings. He has worked in the Vacuum Industry since 1993 in a variety of technical, marketing and sales roles and is now Global Applications Manager for the Atlas Copco Scientific Vacuum division which includes the Leybold, Edwards and Gamma Vacuum global brands. 

Andrew is the Chair of the UK Institute of Physics Vacuum Group Committee.

In November 2018 Andrew was invited to be an active Vacuum Science World contributor, and to share his wealth of vacuum expertise and application know-how across our community and is now Editor of Vacuum Science World.

Jinane Haddad - Vacuum Science World

Jinane Haddad

Global Application Manager

Prior to working in Atlas Copco, I was a Doctoral candidate at the Forschungszentrum Juelich and the University of Cologne, where I worked in Perovskite Solar Cell research. I have a Diplome Ingenieur from the INP de Bordeaux in France where I graduated in 2015 as an Ingenieur de Chimie et Physique with a specialty in energy storage and conversion. I have been working at Atlas Copco since July 2020 as Global Applications Manager in the Scientific Vacuum Division, where I am mainly in charge of Leybold Cryogenic products.

In 2021 I was invited to become a contributor to Vacuum Science World, to share knowledge in applications know-how for cryogenic vacuum applications and in areas relating to my research.
