Feliciano Giustino is an Italian physicist and materials scientist who works in computational condensed matter physics. He is a professor of physics at the University of Texas at Austin, where he holds the W. A. "Tex" Moncrief, Jr. Chair in Quantum Materials Engineering and directs the Center for Quantum Materials Engineering at the Oden Institute for Computational Engineering and Sciences.
Giustino's work includes first-principles theory and software for electronâÂÂphonon interactions, including development of the EPW code distributed with Quantum ESPRESSO, and studies of halide perovskite semiconductors. He authored the textbook Materials Modelling Using Density Functional Theory: Properties and Predictions (2014) and the review article "ElectronâÂÂphonon interactions from first principles" in Reviews of Modern Physics (2017). He was elected a Fellow of the American Physical Society in 2020 and was named a 2025 Guggenheim Fellow in physics.
Giustino earned an MSc degree in nuclear engineering from the Politecnico di Torino in 2001 and a PhD in physics from the ÃÂcole Polytechnique Fédérale de Lausanne (EPFL) in 2005. During 2000âÂÂ2001 he was a research fellow in the Experimental Physics Division at CERN in Geneva, Switzerland. After completing his doctorate he carried out postdoctoral research at the University of California, Berkeley and at Lawrence Berkeley National Laboratory (2005âÂÂ2008).
In 2008 Giustino joined the Department of Materials at the University of Oxford as University Lecturer in materials modeling and became a Governing Body Fellow of Wolfson College. He was promoted to associate professor in 2013 and to professor of materials in 2014. In 2012 he received a Leverhulme Research Leadership Award for research on biomimetic solar cells.
In 2017âÂÂ2018 he held the Mary Shepard B. Upson Visiting Professorship in Engineering at Cornell University. He joined the University of Texas at Austin in 2019.
Giustino's research focuses on first-principles electronic structure theory and high-performance computing for materials, including calculations of electronâÂÂphonon interactions and studies of halide perovskite semiconductors.
Giustino's 2017 review article in Reviews of Modern Physics, "ElectronâÂÂphonon interactions from first principles", surveys theoretical and computational approaches for ab initio calculations of electronâÂÂphonon couplings and applications to superconductivity, transport, and optical spectroscopy.
He co-developed the EPW code (ElectronâÂÂPhonon coupling using Wannier functions), distributed as part of the Quantum ESPRESSO package.
Giustino has worked on the theory of halide perovskite semiconductors for solar cells and light-emitting devices. In a 2016 perspective article in ACS Energy Letters, co-authored with Henry J. Snaith, he discussed strategies for replacing lead in perovskite solar absorbers and surveyed candidate lead-free materials.
In 2024 Giustino and collaborators reported topological polarons in halide perovskites using first-principles simulations.
