Jacinda Ginges is a theoretical physicist in the School of Mathematics and Physics at UQ. Her research is directed towards atomic tests of fundamental physics, involving development and application of high-precision many-body methods for heavy atoms. Her areas of expertise include high-precision studies of fundamental symmetries violations (parity, time) and probes of nuclear structure. Atomic parity violation studies provide some of the tightest constraints on possible new physics beyond the standard model of particle physics, complementing searches for new physics at the LHC and dark matter searches. Studies of parity- and time-reversal-violating atomic electric dipole moments tightly constrain possible new sources of CP-violation appearing in theories beyond the standard model.

Working in theoretical atomic physics and particle astrophysics. My research focusses on high-precision atomic structure calculations, and how atomic processes can be used for testing fundamental theories, probing for physics beyond the standard model, and searching for dark matter. This is complimentary to the high-energy tests performed at CERN. Some research highlights include: searching for variations in the fundamental constants near the super-massive black hole at the centre of our galaxy [1]; using decades of archived atomic clock data from the GPS satellites to search for signatures of dark matter [2]; performing high-precision calculations of symmetry violations in atoms, allowing the most precise low-energy test of the standard model to date [3-5]; and proposing and quantifying novel experimental signatures of dark matter that exploit atomic (rather than the typical nuclear) phenomena, opening the door to a wide range of previously “invisible” models [6-9].

Dr Gabriele Tartaglino-Mazzucchelli's research interests include topics in theoretical physics of fundamental interactions and mathematical physics like supersymmetry, supergravity and superspaces in various space-time dimensions, quantum field theory, extended supersymmetry, covariant formulations of superstrings, complex geometry, quantum gravity, holography, (A)dS/CFT and integrability.

Since October 2019 Dr Tartaglino-Mazzucchelli has joined the School of Mathematics & Physics at the University of Queensland (UQ) as Senior Lecturer (Level C), Australian Research Council (ARC) Future Fellow. Currently, he is an Amplify Fellow at UQ.

Dr Tartaglino-Mazzucchelli's obtained his PhD at the University of Milano Bicocca in November 2006. After that, and before joining UQ, he has held several academic appointments and fellowships in Australia (UQ and The University of Western Australia), Belgium (KULeuven U.), Sweden (Uppsala U.), Switzerland (Bern U.), and the USA (Maryland U.).

So far in his career, Dr Tartaglino-Mazzucchelli's successfully attracted competitive research grants and awards for approximately 2.5 million Australian dollars, including, among other grants, a Marie Curie fellowship, an ARC DECRA award, and an ARC Future Fellowship – some of the most prestigious fellowships available to early and middle career researchers in Europe and Australia – and two ARC Discovery Projects, one recently awarded as first Chief Investigator.
