I am a Research Fellow in the Physics Department at the University of Warwick.

Research interests

• understanding, controlling and exploiting the properties of colour centres and dopant atoms in diamonds.
• developing quantum and classical sensors that exploit the extreme and unique combination of properties offered by diamond.
• developing and applying processing, functionalisation, and micro- and nano-fabrication techniques suitable for diamond.
• developing new techniques in magnetic and optical spectroscopy.
