PhD Students


Toby BiToby Bi
Toby has a BSc in physics and computer science, BSc (Hons) in physics, and an MSc in physics, all from The University of Auckland, New Zealand. His master’s research project was on parametric oscillations in magnesium fluoride microresonators supervised by Stuart G. Murdoch in the nonlinear photonics group. Toby joined the group at MPL in 2020 to pursue a PhD as part of the MICROCOMB Marie Skłodowska-Curie Innovative Training Network. [at]


Graeme Campbell
Graeme is an external PhD student located at the University of Strathclyde and supervised by Prof Gian-Luca Oppo. He achieved his BSc (Hons) in mathematical physics at the University of Edinburgh before moving to the University of Strathclyde to obtain an MSc in physics and start his PhD in the ‘theory and simulation of frequency combs in micro-resonator devices’.
