Dr Robert D. J. Oliver is a Lecturer in Sustainable Materials in the Department of Materials Science and Engineering, University of Sheffield. Robbie is interested in studying materials that have the potential to mitigate the effects of climate change, especially through developing more efficient solar energy generation.  To achieve this goal, his research focuses on understanding the interplay between the photophysics, device physics and materials properties of novel semiconducting materials with an emphasis on metal halide perovskites. 

Robbie received his MPhys in Physics from Corpus Christi College, Oxford in 2018. Following this, Robbie was at St Anne's College, Oxford where he conducted his DPhil studies under the supervision of Prof Henry Snaith FRS and Prof Michael Johnston, defending his thesis entitled "Interfaces in Metal Halide Perovskite Photovoltaics" in 2022. Robbie won the prestigious MRS Graduate Student Award in 2022 for the quality of his DPhil work. In 2022, Robbie moved to the Department of Physics and Astronomy, University of Sheffield where his postdoctoral work studying the influence of strong light-matter coupling on the photophysics of organic materials was supervised by Prof Jenny Clark and Prof Julia Weinstein. In October 2023, Robbie began his Lectureship in the Department of Materials Science and Engineering, University of Sheffield.

Robbie has been recognised as a 'SuperVisionary' by his group for the quality of his PhD supervision. In October 2025, Robbie will join the Institute of Physics Energy Group Committee.

Charlie comes from Kendal in the Lake District and finished his MChem at Oxford in 2024. In his Masters project, Charlie worked on perovskite nanoplatelets studying their growth chemistry and stability. Charlie’s PhD focuses on tracking the energy transfer in solar cell devices; in particular probing energy losses and examining the stability of mixed halide perovskite solar cells. In his spare time, Charlie enjoys a wide range of sports such as running, cycling, cricket and football.

Charlie is the recipient of the prestigious Overli Foundation Scholarship. Charlie is co-supervised by Dr Alex Ramadan (Sheffield Physics).

Shahad comes from Saudi Arabia, she started her Masters in Material Science and Engineering at the University of Sheffield. Her research focuses on halide segregation in 2.0 eV metal halide perovskites. Previously, she worked in the semiconductor field in Saudi Arabia, specializing in metal organic chemical vaper deposition (MOCVD) and processing LEDs. 

She enjoys art museums and exploring nature, especially scuba diving in the Red Sea.

Amber comes from Hong Kong and is a final-year bachelor's student in the Department of Materials Science and Engineering at the University of Sheffield. Her current research focuses on assessing the stability of perovskites in technologically relevant applications. In particular, she will analyse charge transport layer / perovskite heterojunctions under space-like conditions. Amber is enthusiastic about working with the team to conduct drift-diffusion simulations and experimental work over the coming year. 

Beyond her academic pursuits, she has a keen interest in music and art, and has explored various sports such as archery and ice skating during her stay at the university.
