| Bibliography: | Manuela Wallesch joined the Karlsruhe Institute of Technology (KIT), Germany, to study chemistry in 2007. She graduated in 2012 (organic photovoltaics) and started her Ph.D. thesis (ongoing) in the group of Prof. Dr Stefan Bräse, in collaboration with Prof. Dr Clemens Heske (KIT and University of Las Vegas, Nevada, USA) on the physical properties and advanced spectroscopy on copper complexes, which can be used as OLED-emitters. She is a fellow at the Biointerfaces International grad school at KIT and is currently obtaining an Master in Business Adminstration (MBA) with the Collège des Ingenieurs in Paris, France, in parallel to her scientific studies. Charlotte Fléchon studied Chemistry and Physics at the Ecole Nationale Supérieure de Chimie et de Physique de Bordeaux (ENSCPB), France. After graduation, she completed a Ph.D. focused on Organic Light-Light Emitting Diodes at University College London (UCL) and joined CYNORA in January 2013. Stefan Bräse studied in Göttingen, Bangor (UK) and Marseille and received his Ph.D. in 1995, after working with Armin de Meijere in Göttingen. After post-doctoral appointments at Uppsala University (Jan E. Bäckvall) and The Scripps Research Institute (K. C. Nicolaou), he began his independent research career at the RWTH Aachen in 1997 (associated to Dieter Enders). In 2001, he finished his Habilitation and moved to the University of Bonn as professor for organic chemistry. Since 2003, he is full professor at the Karlsruhe Institute of Technology and since 2012 director of the Institute of Toxicology and Genetics at the KIT. His research interests include methods in drug-discovery (including drug-delivery), combinatorial chemistry towards the synthesis of biologically active compounds, total synthesis of natural products and nanotechnology. Michael Danz studied chemistry at the Universtity of Marburg, Germany, where he graduated in 2008. Between 2008 and 2011 he worked on his Ph.D. thesis in the group of Prof. Dr Gerhard Hilt (department of organic chemistry, University of Marburg) in the field of transition metal catalyzed transformations. In November 2011, Michael joined CYNORA and is now working in the R&D department on the development of new organoelectronic materials. Daniel M. Zink studied chemistry in Karlsruhe, Germany (Karlsruhe Institute of Technology), where he graduated in 2010. Between 2010 and 2013 he worked on his Ph.D. thesis in the group of Prof. Dr Stefan Bräse (department of organic chemistry, Karlsruhe Institute of Technology) in a collaboration project with CYNORA about new emitting TADF materials based on polynuclear copper complexes. Since 2013, he works as R&D scientist at CYNORA in the field of developing new iridium-free TADF materials for solution- as well as vacuum-processed OLEDs. Jose Navarro has studied Physics and Electronics at the University of Seville, Spain. After completing his Masters and Ph.D. in organic electronics at the University Paul Sabatier (Toulouse 3)/Essilor International, France, in 2008, he has worked as a Project Manager and R&D director in the photovoltaic industry in Spain (CENER and Gadir Solar), and in parallel, he obtained a Masters in business administration (MBA) and in Quality Management. In 2011 he was employed as an R&D engineer for the CNRS in Strasbourg. Jose Navarro has been employed at CYNORA as R&D scientist since February 2013, and his work as quality manager began in March 2014. Thomas Baumann is the CSO of CYNORA and the scientific coordinator in the company. He has a strong background in organometallic synthesis, along with an in-depth understanding of the field of organic electronics. He graduated from the University of Bayreuth, Germany and completed his Ph.D. in organic chemistry at the Karlsruhe Institute of Technology under the supervision of Prof. Dr Stefan Bräse in 2007. After his Postdoc at the University of Cambridge with Prof. Dr Rachel O'Reilly, he joined CYNORA as Co-CEO in 2008. Since then, he is responsible for the R&D and IP unit at CYNORA. He is co-author of several publications and co-inventor of most of CYNORA's patent applications. Anand Verma has gained an engineering degree from Manipal Institute of Technology, India and MSc. from TU Chemnitz, Germany, in Printing & Media Technology. He has four years of professional experience spanning from commercial printing and quality management to R&D, with a focus on Organic & Printed electronics at Novaled AG, Germany and Holst Centre, The Netherlands. Anand has experience in developing inks and printing of OLEDs and OPVs through digital & conventional printing processes. He is working with CYNORA since May 2014 as an R&D Scientist, being responsible for the development of inks and printing of TADF OLEDs through Inkjet printing. Daniel Volz studied chemistry in Karlsruhe, Germany (Karlsruhe Institute of Technology), where he graduated in 2011. He joined the Karlsruhe School of Optics and Photonics (KSOP) in 2011 and worked on his Ph.D. thesis in the group of Prof. Dr Stefan Bräse, in a collaboration project with CYNORA. After completion of his thesis, which was aimed on the development and studies of new copper complexes and new processing concepts, he received his Ph.D. in 2014. At CYNORA, he his engaged in the R&D department and acting as a connector between R&D and the IP unit. His research interests as a R&D scientist at CYNORA are aimed towards the development of new, sustainable emitting materials for OLEDs and exploration of their photophysical properties. Daniel was awarded with the Carl-Roth-prize for sustainable use of chemicals in 2015. ObjectType-Article-1 SourceType-Scholarly Journals-1 ObjectType-Feature-2 content type line 23 |
