Emeritus Scientific Members

Stephan Borrmann, Director of the Particle Chemistry Department from 2001 until 2025

Stephan Borrmann was born in 1959 in Mainz.1991 he completed his PhD in physics focusing on Experimental Meteorology at the Johannes Gutenberg University in Mainz. From 1998 to 2000 he headed the Research Group for aerosols of the Institute of Chemistry and Dynamics of the Geosphere at Research Centre Jülich GmbH. In 1999 he completed his habilitation in the field of meteorology. In 2001 Stephan Borrmann was appointed Director of the newly founded Cloud Physics and Chemistry Department. (The Department was renamed in 2005, becoming the Particle Chemistry Department). At the same time, Mr. Borrmann was appointed Professor of Experimental Meteorology in the Physics Department of Mainz University. The department's research focused on physical and chemical processes in clouds, with a particular focus on polar clouds in the border region between the troposphere and the stratosphere.

Profile

Albrecht W. Hofmann, Director of the Geochemistry Department from 1980 until 2007

Albrecht W. Hofmann (born in 1939) was appointed Director of the newly founded Geochemistry Department in 1980. His department researches large-scale geological processes, such as the formation of continental and oceanic crusts, the chemical differentiation of the Earth's mantle and the circulation of present-day and former oceans. The department uses mass spectrometric measurements of isotopic abundancies to determine the absolute age of rocks. It also uses isotopic abundancies and trace element contents to determine the origin of volcanic lava from the Earth's mantle or crust and studies the long-term processes used by the Earth's mantle to recycle old crust. The department also performs experiments to study the pressure, temperature and other physical-chemical properties in fusions and mineral transformations that take place deep inside the Earth. Albrecht Hofmann retired in 2007.
