Overview

Dr Jacqui Romero is an expert in experimental quantum information. Her research is focused on using higher-dimensional systems for exploring curious quantum physics phenomena and developing future quantum technologies. She is the group leader of the research team Qudits@UQ, there's more information on her group's webpage.

Jacqui was born and bred in Manila, Philippines. Hearing her high school physics teacher complain about quantum physics, she became curious and googled "quantum physics"—she has been hooked ever since. She holds BS Applied Physics magna cum laude and MS Physics degrees from the University of the Philippines. She finished her PhD at the University of Glasgow (in sunny Scotland!) where she was a researcher for seven years. In 2015, she moved to Brisbane to join the Quantum Technology group at the University of Queensland. In 2016 she took up an ARC DECRA fellowship with the same group. In 2019, she took up a Westpac Research Fellowship and formed her own team, Qudits@UQ. Jacqui is recognised for moving the shape of photons to mainstream quantum information. She has received several prestigious national and international awards which include: a L'Oreal-UNESCO For Women In Science award in 2017 (one of four in Australia), the Ruby Payne-Scott Medal of the Australian Institute of Physics for excellence in early-career research in 2018, and a L'Oreal-UNESCO For Women In Science International Rising Talent Award in 2019 (one of fifteen awards globally).

She is currently a senior lecturer and Westpac Research Fellow. She is also a chief investigator at the Centre of Excellence For Engineered Quantum Systems (EQUS).

Outside work, she is a busy mum to three lovely boys, and an occasional painter. She also loves sharing her research to the wider community, example here.
