Giuseppe Barca

Associate Professor Giuseppe Barca serves in the School of Computing and Information Systems within the Faculty of Engineering and Information Technology at the University of Melbourne. His research centers on high-performance computing and quantum chemistry, pioneering exascale algorithms for GPU-accelerated electronic structure calculations, including energies, gradients, and ab initio molecular dynamics at unprecedented biomolecular scales. Barca led Australia’s contribution to the U.S. Department of Energy’s Exascale Computing Project from 2018 to 2023, partnering with U.S. national laboratories such as Oak Ridge and Argonne, academic institutions like Georgia Tech, and industry leaders including NVIDIA, Intel, AMD, and Cray. This effort delivered the first quantum-accurate biomolecular simulations at exascale. As Chief Investigator of the PaCER initiative from 2021 to 2023, he directed the creation of EXESS, a GPU-native platform for extreme-scale electronic structure computations. His team established four successive world records from 2020 to 2024 for the largest quantum chemical simulations at the wave function theory level.

Barca’s innovations earned the 2024 Gordon Bell Prize from the Association for Computing Machinery for the breakthrough titled “Breaking the Million-Electron and 1 EFLOP/s Barriers: Biomolecular-Scale Ab Initio Molecular Dynamics Using MP2 Potentials,” achieving the first wavefunction-based quantum molecular simulation at biological scale on the Frontier supercomputer and surpassing the double precision exaflop/s barrier for scientific applications. In 2025, he received the Dirac Medal from the World Association of Theoretical and Computational Chemists, the premier global honor for computational chemists under 40. Key publications include “Recent developments in the general atomic and molecular electronic structure system” (The Journal of Chemical Physics, 2020) and “Simple models for difficult electronic excitations” (Journal of Chemical Theory and Computation, 2018). These advancements enable quantum-accurate modeling of biological systems with near-experimental precision, transforming drug discovery by accelerating and reducing costs for new therapeutics targeting challenging diseases. Barca co-founded QDX Technologies in 2023, where he heads research to commercialize high-performance quantum simulations and AI-driven molecular modeling for biotechnology and pharmaceuticals.
