My primary research interest is the development of novel nanofabricated device platforms for manipulating light and sound waves at the nanoscale and engineering controlled interactions between them, and other solid state systems. My current research thrusts are along three main directions, all underpinned by advances made in my group on pushing the operation frequency and efficiency of light-sound interactions in guided wave devices: building resonant acousto-optic quantum transducers to translate quantum states between the microwave and optical frequency domains for connecting distributed superconducting, spin and trapped ion qubit platforms [Balram et al., Nat. Phot. 2016; Valle et al., Opt. Lett. 2019; Wu et al. Phys. Rev. Appl. 2020]; shrinking mobile RF front-ends by ~100x by applying ideas from integrated photonics to guided wave acoustics [Valle et al., Appl. Phys. Lett. 2019]; and applying modern developments in RF engineering to an old problem (spin detection) and providing a route towards improved sensitivity by ~8 orders of magnitude.

My work pushes the state of the art in nanofabrication methods and, the performance of devices and systems enabled by this establishing Bristol as a centre for excellence in nanofabrication. To enable this, my group also develops novel metrology tools that allows us to probe and quantify wave phenomena at the nanoscale. My interest in metrology is a natural outgrowth of spending three very enjoyable years as a postdoctoral fellow, working with Kartik Srinivasan at NIST Gaithersburg. Before that, I was a PhD student with David Miller at Stanford.
