Yorrick Boeije

Barnaby Lewis

Yorrick is interested in how nuclear dynamics affect exciton and charge transport at the femtosecond timescale in various optoelectronic materials. When combining this temporal resolution with nanometer spatial resolution, these interactions may be linked to local heterogeneous features, such as defects. This could elucidate the role of defects, as well as the intimate connection with nuclear dynamics involved in nonradiative decay, which should be minimized to enhance optoelectronic performance. Yorrick completed his BSc and MSc in Chemistry in Amsterdam. Started October 2021.

Barnaby graduated from the University of Warwick with an integrated master's degree in 2019. During his 3rd year, he completed a 14-week research project on the synthesis and structure of iron spin-crossover complexes in the Murray Group of Monash University, Australia. His final year MChem project with the Stavros Group, Warwick, focussed on the ultra-fast kinetics of molecular switches using transient absorption spectroscopy. After a 2-year break from research in industry, he will be using time-resolved spectroscopy to study emerging semiconductor materials including perovskites and perovskite-inspired materials. Started 2021.
