My work as a theoretical physicist centres on addressing the fundamental question concerning how our macroscopic, classical world of everyday experience emerges from the microscopic, counterintuitive quantum world. Relevant investigations range from collaborating with experimentalists (Alex Rimberg, Dartmouth; Keith Schwab, Caltech) and theorists (Andrew Armour, Nottingham) on mesoscale electro(opto)mechanical systems that straddle the micro-macro worlds ... to constructing fundamental theories on the possible role of gravity as an enforcer of classicality in the macroscopic domain. I also work on analogue gravity in superconducting circuit systems, in particular finding ways to demonstrate Hawking radiation from analogue event horizons (in collaboration with Haruna Katayama, Hiroshima). And I have been exploring ways to use sound to learn about the quantum realm, both through creating quantum soundscapes (sonifying data from quantum device experiments) and quantum music.
