John received a BSc in Biochemistry from Imperial College London, UK before completing a DPhil in Biochemistry at the University of Oxford, UK in membrane protein structural biology under the guidance of Prof. Simon Newstead. In 2016, John moved to the UK synchrotron facility, Diamond Light Source, where he developed serial crystallography techniques on beamline I24. John was then awarded a PSI-Marie Skłodowska Curie Fellowship in the MX group at PSI in 2019 to continue these investigations. John is now the serial femtosecond crystallography (SFX) beamline scientist on Cristallina, the third experimental station of SwissFEL's ARAMIS beamline.

Scientific Research

Since 2018, John has tried to develop strategies to create the samples required for modern serial crystallography experiments at either synchrotrons or XFELs. These include methods to create large volumes of micro-crystals and fixed-target mounting and loading techniques. John is now also working towards the realization of a fixed-target endstation on Cristallina. The endstation's primary purpose will be high-throughput SFX for room-temperature time-resolved experiments.
