Ana joined MSL in 2021. Prior to joining, she worked in several areas of cold atom physics, both in academia and industry.

Ana did her PhD at Otago University within the Dodd-Walls Centre for Photonic and Quantum Technologies, where she developed an optical collider for ultracold atoms. This apparatus can access extremely low collision energies with high precision, which enables study of interatomic interactions with a well-defined collision energy and helps gain insight into fundamental atomic and molecular properties.

After her PhD, Ana continued working as a postdoctoral fellow at Otago for another year, extending the capabilities of the optical collider and working with ultracold fermions. Following this, she moved to Durham University in the UK and joined the Quantum Light and Matter group as a postdoc, where she worked on several experiments over five and a half years. Early on at Durham, she studied rotational dynamics of Bose-Einstein condensates and analysed superfluid vortex lattice formation and decay using computer vision methods. Later, she worked on bright-matter-wave soliton interferometry, where she developed a prototype soliton interferometer with potential for interrogation times on the order of 20 seconds. Following this, she developed a brand new experiment designed to assemble dipolar molecules from single trapped atoms. This project is part of the Quantum Science with Ultracold Molecules collaboration between Durham University, Imperial College London, and Oxford University, which aims to create and fully control dipolar molecules for applications in quantum computing, quantum simulation, and fundamental physics.

Following several years as a postdoc, Ana joined Atomionics as a senior research scientist. Atomionics is a quantum sensing start-up company based in Singapore. Ana’s work focussed on designing and building a mobile cold atom gravimeter for applications such as natural resource detection, underground feature detection for construction and tunneling, detection of underground infrastructure in urban environments, as well as general purpose environmental applications such as sea level monitoring.
