Management

Dr. Arnd Greiling

Chief Executive Officer (CEO)

Dr. Arnd Greiling is an outstanding expert in the development of innovative material systems for III/V semiconductors on silicon. The doctorate chemist began his research on material systems during his studies and scientist work at the Philipps-Universität/Marburg. After completing his doctoral thesis on the topic of "Elementorganical Compounds of Arsenic – Alternative Sources for CVD" he set up a forerunner company and started the research project "development and synthesis of novel precursors for MOCVD" (in cooperation with Siemens and Alcatel). Within only two years of developing a complete new material system for semiconductor-production, his innovation was honored with the prestigious "Karl-Heinz-Beckurts Preis" award from the German Federal Ministry of Education, Science, Research and Technology. Following the sale of the company to Akzo Nobel and subsequently its repurchase, Dr. Greiling directs Dockweiler Chemicals as CEO with a focus on expansion in international businesses.

Dr. Andreas Salzmann

Chief Technology Officer (CTO)

Dr. Andreas Salzmann started his career in science at the Chemical Department and Structure and Technology Research Lab of Philipps-Universität/Marburg. The main focus of his works is research in the field of metalorganics from main and subgroup-elements (cyclopentadienyl of Na,K,Sb,Hg,Zn,Cd). During his scientific work he also got to know Dr. Arnd Greiling and, together with Prof. Wolfgang Stolz, he founded the then forerunner company Mochem. As company representative and production manager he established production. His current work’s focus remains in the building and expansion of production capacities for the international market.

Dr. Jörg Koch

Chief Marketing Officer (CMO)

The doctorate physicist Dr. Jörg Koch also began his career in science at the Structure and Technology Research Lab of Philipps-Universität/Marburg. The main focus of his research was in the deposition and analysis of semiconducting materials. Within this time, project work on device development with Infineon Technologies was established. In his later years he became specialized in the area of marketing, initially as manager in the Compound Semiconductor Division at Mochen, where he was responsible for the international direct marketing of novel process-chemicals for CVD applications, later as Technical Marketing Manager at Akzo Nobel. There his functions were primarily in technical marketing and sales support for high purity metalorganics, where he internationally launched several new products as well as joined development projects with customers to implement new technologies. Dr. Jörg Koch is responsible for international marketing at Dockweiler Chemicals.

Bernd Scheld

Chief Financial Officer (CFO)

Bernd Scheld is an experienced business manager and responsible for Dockweiler Chemicals’ entire area of finance. After his studies in business economics, Mr. Scheld was successfully employed as a system analyst at large, well-known German companies such as Allianz and the German Association of Transaction Systems (Gesellschaft für Zahlungssysteme; GZS) in Frankfurt. Subsequent to working for ten years in systems analysis, Bernd Scheld took over as head of a medium-sized company group and was appointed there as Chief Representative. He has considerable business management orientated leadership experience, far-reaching experience in corporate finance and in the establishment of new companies. Joint ventures and exit scenarios are also among his field of competencies.

Kai Ronzheimer

Head of Production

Kai Ronzheimer is responsible for the entire production techniques and processes as well as the entire quality management at Dockweiler Chemicals. The Philipps University laboratory technician is a state certified environmental protection engineer trained at the University for Environmental Technology in Frankenberg. His career started as the laboratory head at Mochem, out of which Dockweiler Chemicals later emerged. During the time the company belonged to Akzo Nobel, Kai Ronzheimer was head of the entire production. His expertise in the safe and sustainable manufacturer of high purity process-chemicals for CVD applications now spans over 15 years.

Prof. Dr. Wolfgang Stolz

Scientific Advisor

Dr. Wolfgang Stolz is co-head of Structure and Technology Research Laboratory at the Department of Physics at Philipps-Universität Marburg. After his studies, diploma thesis and PhD thesis in Karlsruhe, Heidelberg and Stuttgart, the physicist Dr. Wolfgang Stolz started his scientific career at Max-Planck-Institute for Solid State Research in Stuttgart, which led to a longer research residence at the Basic Research Laboratories of Nippon, Telegraph and Telephone Corp. NTT Tokyo/Japan. 1989 resulted in a move to the Phillips-Universität Marburg/Germany as Head of the Central Technology Laboratory at the Structure and Technology Research Lab and Department of Physics. He was the cofounder of Mochem, a spin-off of the research activities “Novel precursors for semiconductor epitaxy”. In 1994, the Habilitation in Experimental Physics on “Material science aspects and physical properties of novel III/V semiconductor heterostructures” took place. Dr. Wolfgang Stolz is supervisor and speaker in several international research committees, entrepreneur and adjunct professor at the College of Optical Sciences, University of Arizona/Tucson. In addition, he is the managing coordinator of the Joint Research Program “Monolithic integration of GA/NAsP)-based laser structures on silicon” of the German Ministry of Education and Research (BMBF).

Prof. Dr. Kerstin Volz

Scientific Advisor

Prof. Kerstin Volz is partner at Dockweiler Chemicals GmbH and since 2009 Heisenberg Professor for Experimental Physics and Co-Leader at the STRL (Structure and Technology Research Lab) of Philipps University Marburg. She received her diploma in physics from Augsburg University in 1996. In 1999 she obtained her PhD from the same university. After several research visits at Osaka National Research Institute and Nagasaki Institute of Technology, as well as a postdoctoral stay at Stanford University, she joined Philipps-Universität Marburg as a Junior Group Leader (in the framework of a Topical Research Group of the DFG). After a professorship at the Humboldt-Universität of Berlin, she was appointed as a professor in Marburg and will serve there as speaker of the Research Training Group “Functionalization of Semiconductors” starting in 2012. She has received the following awards: Graduate Student Award of EMRS (1996); Feodor-Lynen scholarship of Alexander von Humboldt foundation (2001); guest professorship of Humboldt Universität of Berlin (2008); Heisenberg professorship of DFG (2008); and the Patricia Pahamy Prize for best teaching (2009). Her research interests include the synthesis (MOVPE) and quantitative transmission electron microscopy of novel functional materials.
