Experienced at all levels, including lab and lecture modules such as First year Lab Head, PHY102 lecturer (Light and Optics), PHY250/251 lecturer (Solids), 2nd Year Tutor, PHY382/482 (Semiconductor Physics and Devices), PHY391 (Quantum Information Lab), PHY480 MPhys project supervision.
Research-led teaching - I led the development of a specialist UG laboratory for quantum optics experiments that are closely aligned with key departmental research activities.
This unique (in the UK) UG lab facility, provides L3 students with a deep learning experience that equips them for further PhD or industrial research in quantum information science. The facility is used on Open Days as an example of our investment in innovative, research-led teaching.
- Professional activities and memberships

Internal roles
Head of Department (Sep 2022 - present)
Departmental Director of Teaching 2016-2018. Led our successful accreditation (all UG programmes) by the Institute of Physics in 2017, writing and preparing detailed documentation and hosting the visiting panel. Chair our Teaching Committee, Staff Student Committee and Exam Boards and I am a member of the Departmental Executive Committee and Faculty Learning and Teaching Committee. Organise and run an annual Departmental Teaching Away Day, providing time and space for staff in the department to reflect on teaching and to explore current issues such as PLA and assessment.
Assistant Faculty Director of Learning and Teaching 2015-2016. In this role I acted as Achieve More Faculty Lead (2014-2016), working closely with the FDLT, relevant University committees and professional services teams to provide leadership and direction for Achieve More in the Faculty of Science.
Previous roles include Disability Liaison Officer (DLO) and Chair of Condensed Matter teaching vertical committee.
