Andrew Rosen is an Assistant Professor of Chemical and Biological Engineering at Princeton University, where he started his independent faculty career in 2024. Andrew earned a B.S. in Chemical Engineering from Tufts University and his Ph.D. in Chemical Engineering at Northwestern University, where he studied metal–organic frameworks for oxidation reactions with Prof. Randy Snurr and Prof. Justin Notestein. Upon graduating in 2021, Andrew moved to the University of California, Berkeley where he pursued independent postdoctoral researcher as a Miller Research Fellow. At UC Berkeley, he worked with Prof. Kristin Persson in the Department of Materials Science and Engineering on single-atom alloys and the development of new software infrastructure for computational materials science.

At Princeton, the Rosen Group leverages recent advances in quantum chemistry, high-throughput computing, and machine learning to inform the design of new materials. As quantum-chemical engineers, the group is interested in materials with emergent catalytic properties arising from exotic electronic structure phenomena in solid-state materials. The group is also focused on applying new computational methods based on machine learning interatomic potentials to address many of the complexities of materials that cannot easily be captured in traditional first-principles simulations.

Andrew's scholarship has been recommended by numerous honors and awards, including being named a CAS Future Leader, a Breakthrough Energy Explorer Fellow, and receiving a Commendation for Outstanding Teaching twice by the School of Engineering and Applied Sciences at Princeton. Andrew is particularly passionate about open-source science and is a developer or maintainer for many widely adopted software packages and databases in the computational materials science community, including the Atomic Simulation Environment, Pymatgen, the Materials Project, the Quantum MOF Database, and his dedicated group code, the Quantum Accelerator.
