Department Chemical Biology I (Dorothea Fiedler)

Group Leader

Dorothea Fiedler

Dorothea grew up in the most beautiful city in Germany: Hamburg. She went to college at the University of Wuerzburg and did her Diploma work at UC Berkeley. She decided she liked the United States for many reasons that include Thanksgiving (and also German beers are overrated), so she stayed at Berkeley for her Ph.D. She worked in the Raymond and Bergman labs, studying host-guest systems and their application to catalysis. She then moved across the Bay to UCSF, where she joined the Shokat lab to investigate signal transduction pathways. She started her academic career at Princeton University but recently relocated to the FMP, Berlin.

Administrative Assistant

Jennifer Trümpler

Jenny grew up in the most “chemical” part of Germany near the Leuna- and Buna-plants. However, she decided to become an animal farmer first. After working in an Irish company for some years, she went back to school to be a bilingual secretary. Assisting the management of a consulting company in Berlin since 2010, she made time to study three evenings a week and graduated in business administration (B.A.). Having found her interest in academia, she switched to the International Office at Eberswalde University for Sustainable Development to support students going abroad and international students studying here. She is happy to assist the Fiedler group in administrative matters. Chocolate is vital for her, she always stores a pile or two in her desk.

Technical Assistants

Katy Franke

Katy was born and raised in the vastness of Brandenburg. During her Abitur she felt that she favors practical work over dry theory. Therefore Katy chose becoming a chemistry laboratory technician over attending university. She started in Potsdam at AnalytiCon AG, later AnalytiCon Dicovery GmbH, and worked on compound libraries based on natural products. Her desire for a change let her defect to Jerini AG in 2006 where she worked in MedChem. In 2009 Katy switched to the compound managment of the Sceening Unit of the FMP. There she familiarized herself with the fascinating side of HPLC and LC/MS based analytics and robots. Since 2015 Katy is part of the Fiedler lab and finds her way through adventurous phosphor-chemistry. She also permanently increases her knowledge of HPLC and LC/MS instruments.
                                              Katy loves mountains, books and music. Some years ago she found her passion for Ju-Jutsu.

Lena von Oertzen

Growing up in the beautiful saxon countryside and graduating in Biotechnologie (B.Sc.) in a small town called Zittau, Lena decided it was time for some excitement. Berlin was calling and Lena, preferring good old work in a lab over dry studies, moved to start her first job at Jerini AG searching for small peptide drug compounds. When the company was sold (L. has nothing to do with that) Lena, figuring industry business was not her kind of thing, changed to academia and worked in N. Rajewsky's Lab at the MDC, focussing on microRNA studies in C. elegans, followed by the Haucke Lab at the FMP. She is happy to join the Fiedler Lab to support the biological part of the group and learn something about those phosphates everyone keeps talking about. Lena loves high mountains, swing dancing, cinema and eating a proper steak in Argentina.

Kathrin Motzny

Geboren und aufgewachsen im Ostteil von Berlin vor langer, langer Zeit. Nach der Schule habe ich ein Fachschulstudium zur medizinisch-techn. Laborassistentin absolviert. Direkt nach dem Ende des Studiums fiel plötzlich und unerwartet die Mauer…das ganze Leben stand nun auf dem Kopf. Auch ich musste mich in rasendem Tempo in diese neue Welt integrieren und ging für ca. 10 Jahre nach Stuttgart ins Schwabenländle in die bekannte Kinderklinik, genannt „Olgäle“. Dort arbeitete ich mit wundervollen Kolleginnen zusammen, heiratete meinen langjährigen Freund (auch aus Berlin), wir vermehrten uns und gingen dann mit unserem Sohn zurück in die Nähe unserer Eltern. Nun sollte es richtig zur Sache gehen… wir entwarfen und bauten unser Haus, ich fing am FMP in der Nachwuchsgruppe Protein Engineering von Dr. Freund an und hatte es hier mit völlig neuen Arbeitstechniken zu tun. Inzwischen ist mir vieles vertraut. Im Moment bin ich noch in der AG Computational Chemistry / Drug Design von Dr. Kühne und nun auch schon gleichzeitig hier. In meiner Freizeit habe ich jahrelang am Haus gebaut, nun wird der Garten flottgemacht und den Eltern unter die Arme gegriffen.

Postdoctoral Fellows

Jeremy Morgan

Jeremy grew up in Dunedin, at the bottom of the South Island of New Zealand. He completed a BSc (Hons) in Chemistry at the University of Otago, where his dissertation work on catechol-O-methyl transferase inhibitors was undertaken with Eng Wui Tan. He then moved to the Australian National University in Canberra, Australia to find out what it was like to feel his toes all year round. He obtained his PhD under the supervision of Chris Easton, where he investigated mechanisms controlling the biosynthesis of peptide hormones in human cancer cell lines using techniques from analytical chemistry and chemical biology. Having developed an interest in intracellular signalling and wishing to round out his chemical biology skill set, Jeremy joined the group of Dorothea Fiedler as a postdoctoral fellow to investigate the pyrophosphorylation of peptides and proteins.

PhD Students

David Furkert

David was born and raised in Berlin; by definition the most interesting city in europe. He grew up in Berlin Marzahn-Hellersdorf, the most underrated area of Berlin. In 8th grade he told his teacher that he will study chemistry and so he studied chemistry at Humboldt University. After his bachelor thesis, where he worked on small molecule FRET sensors for sphingolipids, he decided to join the Fiedler lab for his master thesis. He has a passion for judo, which he is practicing for almost 20 years now.

Sandra Schlomach

Sandra was born and raised in Hamburg, in the north of Germany. Although she knew that she would miss Franzbrötchen and Schietwedder, she decided to go further south and study Biochemistry at the University of Bayreuth (B.Sc.). During her Bachelor's studies she discovered an interest in Organic Chemistry. Therefore she decided to combine both of the fields and study Chemical Biology at the Friedrich-Schiller University of Jena (M.Sc.). She spent one semester abroad at the University of Oulu in the beautiful and cold country of Finland where she went ice hole swimming at -23 °C. In her spare time she loves indoor and outdoor climbing.

Minh Nguyen Trung

Being born in Waren on the Müritz but growing up in the Berlin district Friedrichshain Minh early appreciated the advantages of living in the centre of this manifold city. After his Abitur and a coin toss Minh decided to study chemistry at the Humboldt University where he did his bachelor thesis on organocatalysis. Minh came to the Fiedler group for a short research internship but got stuck here somehow and is currently doing his PhD thesis. In his spare time Minh likes indoor-bouldering, JRPGs, board games and making jokes about the outskirts of Berlin (like Spandau).

Tim Kröber

Tim grew up in the exciting city of Berlin, where he finished high school in 2013. After he couldn't decide whether to study some language or chemistry, he eventually chose the latter and definitely more promising path. For his Bachelor thesis in the Börner group at Humboldt University, and a research internship in the Perrier group at Warwick University, Tim investigated different types of peptide-polymer-conjugates. To broaden his scientific horizon he joined the Fiedler group for his Master thesis and learned a lot about chemical biology. The intriguing project and the nice working atmosphere prompted him to extend his stay for his PhD studies, where he interrogates the inositol pyrophosphate metabolism by a chemical-genetic approach. When he isn't occupied with chemistry, he enjoys playing the incredibly thrilling and upcoming sport Darts - and yes, it is a sport.

Arif Celik

Arif was born and raised in Berlin. Ever since he was in high school, he was fascinated by biological processes in the human body. After realizing that nearly everything is based on chemistry, he decided to study chemistry at Humboldt-University, where he did his Bachelor thesis on chemoselective antibody modification in the Hackenberger group. After an internship in the medicinal chemistry department of the Bayer AG, he was keen to combine chemistry and biochemistry, so he joined the Fiedler group for his Master thesis. After his Master thesis, he was seeking for a new adventure outside Germany, so he joined the Novartis AG for a six month internship in Switzerland. Currently, he is a Ph.D. student in the Fiedler group, where he is investigating the chemical pyrophosphorylation of pharmacologically relevant proteins. In his spare time Arif enjoys hiking, drinking black tea with an excessive amount of sugar, spending                                                 time with his family and friends, and spending way too much time to improve his                                                                  Muay Thai skills.
