I am always eager to discuss and learn about cool new things from others who are equally excited about what they do, no matter the field. I look forward to meeting with students, other post-docs, and laureates alike to share ideas, advice, and foster new international collaborations. I additionally look forward to engaging with the Hong Kong scientific community and to learn more about the landscape of research in both Hong Kong and the Greater Bay Area, and the opportunities this will bring to the advancement of the field.

10 years after the first gravitational wave observation by LIGO, the LIGO, Virgo, and KAGRA detectors have opened up new possibilities in the field of gravitational wave astronomy. In their wake, there now lies a new motivation to push even higher in gravitational wave frequency, above a few kHz, to target interesting signatures of potential new physics such as axion super-radiance and primordial black holes, as well as standard model signatures such as neutron star merger ring-down. Targeting this frequency range might require new detection strategies to overcome challenges innate to existing gravitational wave observatories. Inspired by technologies originating in quantum sensing, we propose a new type of optomechanical detector platform to not only target high frequency gravitational waves (HFGWs), but also search for vector dark matter. This setup consists of a nanomechanical membrane resonator with an ultra-high mechanical quality factor, coupled to a laser field inside an optical cavity, where the resonance enhances sensitivity beyond the shot noise limit. The sensitivity is comparable to other HFGW detector concepts while remaining practical, and resonant frequency tunability up to twice the original resonant frequency allows for a competitive broadband measurement. | I am also happy to present on my ATLAS work.
