About Me

Hi, my name’s James, and I’m a physics research student. I currently work at The Australian National University’s Centre for Gravitational Astrophysics as part of the theoretical arm of the quantum-squeezing research group and the detector network benchmarking group.

My research interests include Quantum Optics, Gravitational Waves, and Quantum Squeezing. I enjoy discovering a simple understanding of physical phenomena from complex analytic models. I believe in Open Research and Open Source. My CV is available as a PDF here.

Education

Australian National University (ANU)

Doctor of Philosophy (PhD) in Physics

2022 - present

I have accepted an offer to commence a Physics PhD at ANU in June 2022. This will hopefully involve close collaboration with and visits to The California Institute of Technology (Caltech) in Pasadena CA, USA. My research will involve theoretical work in quantum opto-mechanics motivated by similar goals outlined in my Honours thesis (see below).

Australian National University (ANU)

Bachelor of Philosophy (Honours) in Science with First Class Honours in Physics

2018 - 2021

During my time at ANU, I enjoyed learning through asking many fruitful questions and found good company and help from my peers.

My First Class Honours thesis is available here, in which I explored a novel use of quantum squeezing to improve the sensitivity of gravitational-wave detectors (called Nondegenerate Internal Squeezing). The slides for my final Honours talk to the ANU School of Physics are available here.

Employment

Australian National University (ANU)

Research Officer Grade 5/6 (full time)

February - June 2022

I am currently working as a research assistant at CGA on benchmarking future gravitational-wave detector networks to assess the science case for a detector in Australia. This involved Python programming using an existing package (gwbench) and Bash scripting to interact with Swinburne’s OzStar supercomputer.

Media

Outside of academia

When I am not working in the quantum realm, I enjoy playing games and music with friends. I love storytelling and Dungeons & Dragons. I play the trombone (jazz) and piano accordion (folk) and adore Don Ellis’s Autumn.
