About Me

I am a Postdoctoral Research Associate at the University of Sydney, where I study fast optical transients — particularly afterglows and kilonovae. My work is observational, focused on discovery using multi-wavelength facilities.

I am currently developing search and characterization strategies for afterglows and kilonovae using the Vera C. Rubin Observatory, leveraging its unprecedented data stream.
