Stoichko Dimitrov joined Prof. Durrant’s group in March 2011 as a postdoc to study the mechanism of charge photogeneration at organic donor/acceptor interfaces. Stoichko employs various optical spectroscopic techniques with focus on time-resolved pump-probe spectroscopy, from femtosecond to second time scales. This is combined with device and film fabrication, and device characterisation to reveal the factors determining device short circuit currents and fill factors. His final goal is to communicate with chemists and engineers why their devices do or do not work and how to improve their device performance. In addition, he manages the group laser labs and is the laser safety person of the group.
Prior to joining Prof. Durrant’s group, Stoichko received his Ph.D. in Physical Chemistry from Boston College. His dissertation focused on photoinduced ultrafast processes in semiconductor nanocrystals, SWNT and DNA. During his Ph.D. he acquired technical expertise in femtosecond pump-probe spectroscopy, time-correlated single photon counting, and other basic spectroscopic techniques. He has a M.Sc. from Sofia University and one year experience as a chemist in the Institute of Physical Chemistry of the Bulgarian Academy of Science.
Outside of lab, he enjoys exploring London and spending time with his family.
