The development of highly efficient single junction and multijunction photovoltaics, coupled with the rise of bright and efficient LEDs with high fidelity and a wide color gamut, has placed halide perovskite materials at the centrestage of next generation technologies aimed towards combating climate change and promoting sustainability. During my PhD at Cambridge, I investigated the intriguing optoelectronic properties of solution-processed mixed lead-tin halide perovskites using a combination of fundamental spectroscopic investigation and applied device integration in solar cells and transistors. At Oxford, my postdoctoral research primarily focused on developing thermally evaporated perovskite thin films and heterostructures for high-performance light emitting diodes. 

Since March 2026, I have moved to Imperial College London as a Research Associate in Chemical Engineering, where my work is centred on developing and understanding the mechanistic insights of earth-abundant photocatalysts and photoelectrodes for solar-driven production of essential fuels and chemicals. Concurrently, I maintain my association with Trinity College Oxford as a part-time Stipendiary Lecturer in Engineering Science until September 2026.
