Research interests and activities

My primary research interest is the development of novel nanofabricated device platforms, at the intersection of RF-MEMS and integrated photonics, for manipulating light and sound waves at the nanoscale and engineering controlled interactions between them, and other solid state systems (single-spins and nanomagnets).

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 fortunate to work as a PhD student with David Miller at Stanford.

Contact me

I am currently looking for PhD students in the general areas of piezoelectric microwave to optical quantum transducers (Wiley AQT 2022) and applying modern RF engineering to develop efficient interfaces to spin systems. If you are interested in these areas, or want to chat about nanofabrication for quantum engineering in general and how it will change the world, please get in touch.
