Ms Hannah Stern

Junior Research Fellow, Trinity College

PhD Supervisor: Prof Richard Friend

Optoelectronics Group


Bachelor in Physical Chemistry from University of Otago, New Zealand.

PhD, Optoelectronics Group, Cavendish Laboratory. 

Research Interests

Hannah currently works on using super-resolution microscopy techniques to study emitters in 2-dimensional materials, in collaboration with the Department of Chemistry and Department of Engineering.

During her PhD Hannah used ultrafast spectroscopies to investigate the photophysical properties of organic semiconductors. During her PhD she has worked on understanding the mechanism of singlet exciton fission in solution and the solid state.
