Autorenporträt

Series Editor:
Paul T. Anastas joined Yale University as Professor and iserves as the Director of the Center for Green Chemistry and Green Engineering at Yale. From 2004-2006, Paul Anastas has been the Director of the Green Chemistry Institute in Washington, D.C. Until June of 2004 he served as Assistant Director for Environment at e White House Office of Science and Technology Policy where his responsibilities included a wide range of environmental science issues including furthering international public-private cooperation in areas of Science for Sustainability such as Green Chemistry. In 1991, he established the industry-government-university partnership Green Chemistry Program, which was expanded to include basic research, and the Presidential Green Chemistry Challenge Awards. He has published and edited several books in the field of Green Chemistry and is one of the inventors of the 12 principles of Green Chemistry.

Volume Editors:
Philip Jessop is the Canada Research Chair of Green Chemistry at Queen's University in Kingston, Ontario, Canada. After his Ph.D. (Inorganic Chemistry, UBC, 1991) and a postdoctoral appointment at the University of Toronto, he took a contract research position in the Research Development Corp. of Japan under the supervision of Ryoji Noyori, investigating reactions in supercritical CO2. As a professor at the University of California-Davis (1996-2003) and then at Queen's University, he has studied green solvents, the conversion of CO2 to useful products, and aspects of H2 chemistry. He has presented popular chemistry shows to thousands of members of the public. Distinctions include the Canadien Catalysis Lectureship Award (2004), a Canada Research Chair (2003 to present), and the NSERC Polanyi Award (2008). He has chaired the 2007 CHEMRAWN and ICCDU Conference on Green Chemistry, and serves as Technical Director of GreenCentre Canada.

Walter Leitner was born in 1963. He obtained his Ph.D. with Prof. Henri Brunner at Regensburg University in 1989 and was a Postdoctoral Fellow with Prof. John M. Brown at the University of Oxford. After research within the Max-Planck-Society under the mentorship of Profs. Eckhard Dinjus (Jena) and Manfred T. Reetz (Mülheim), he was appointed Chair of Technical Chemistry and Petrochemistry at RWTH Aachen University in 2002 as successor to Prof. Willi Keim. Walter Leitner is External Scientific Member of the Max-Planck-Institut für Kohlenforschung and Scientific Director of CAT, the joint Catalysis Research Center of RWTH Aachen and the Bayer Company.
His research interests are the molecular and reaction engineering principles of catalysis as a fundamental science and key technology for Green Chemistry. In particular, this includes the development and synthetic application of organometallic catalysts and the use of alternative reaction media, especially supercritical carbon dioxide, in multiphase catalysis. Walter Leitner has published more than 170 publications in this field and co-edited among others the first edition of "Synthesis using Supercritical Fluids" and the handbook on "Multiphase Homogeneous Catalysis". Since 2004, he serves as the Scientific Editor of the Journal "Green Chemistry" published by the Royal Society of Chemistry. The research of his team has been recognized with several awards including the Gerhard-Hess-Award of the German Science Foundation (1997), the Otto-Roelen-Medal of Dechema (2001), and the Wöhler-Award of the German Chemical Society (2009).
