Anna Köhler (scientist)

Anna Köhler FRSC is a German physicist who is a Professor of Physics at the University of Bayreuth. Her research considers electronic processes in organic and organometallic molecules. She makes use of optical and electrical spectroscopy to better understand photo-physical processes. In 2020 she became the first woman to win the Max Born Medal and Prize.

Early life and education

Köhler is from Germany. She attended the Karlsruhe Institute of Technology for her undergraduate studies, where she specialised mathematics. After graduating with a diploma in 1992, Köhler moved to the Faculty of Mathematics at the University of Cambridge.

Research and career

Köhler was appointed Professor of Physics and Chair of Soft Matter Optoelectronics at the University of Bayreuth in 2007. Her research considers organic semiconducting materials for solar cells and light-emitting diodes.[1] In particular, Köhler has studied the spin states of organic semiconductors.[2] Köhler was made Executive Director of the Bayreuth University Centre of International Excellence in 2019.

She is the lead of a Horizon 2020 international training network on thermally activated delayed fluorescence (TADF) OLEDs.[3][4] She has shown that the sidechains of conjugated polymers can serve to planarise the polymer backbone and tune the colour of emitted light.[5]
