Current Group

Post-doctoral Research Associates

Callum Rosenberg 2024-

Callum is an EPSRC Postdoctoral Pathways Fellow and has an interest in dye-sensitised Ti-oxo clusters. Callum studied at the University of Birmingham with the Champness Group for his PhD. His research in the Pike Group includes proton coupled electron transfer in Ce and Ti oxo clusters and studying photochemistry via single crystal top singel crystal transformations. Callum runs the Synthesis & Catalysis Journal Club at Warwick.

Master's Project Stories

Ryan Andrews joined the group in 2021/2022 with a project investigating the mechanism of photoredox reactivity of Ti-oxo clusters. Ryan synthesised new clusters and used them to understand photochemical pathways. His research contributed to a research article which was submitted to a leading journal soon after his project finished.

Alex Veale completed his MChem project in 2021. Alex studied the synthesis of brand new Ti-oxo clusters, using new techniques to functionalise the surface of these clusters whilst retaining the core cluster structure. Alex's new compounds undergo photochemical excitation and following Alex's project the group are now studying the EPR spectroscopy of these intriguing compounds.

Rebecca Murray-Watson studied organocopper chemistry as precursors for Cu based nanomaterials. During Rebecca's project she uncovered the crystal structure of an organocopper coordination polymer, a structure which had eluded full structural characterisation for over 50 years! Rebecca's work is published in organometallics.
