Molecular simulations, often likened to a computational microscope, offer atomic-level resolution of complex chemical behavior and phenomena beginning from the underlying fundamental physics. Such simulations generally rely on 1) an approximate method for propagating the nuclear coordinates of the system (e.g., traditional molecular dynamics, which treats the nuclei as classical particles governed by Newton's equations of motion), and 2) a sufficiently accurate description of the energy of the system with respect to its atomic coordinates, i.e., a potential energy surface (PES), which is an approximate solution to the Schrödinger equation in the Born-Oppenheimer approximation. While *ab initio* electronic structure methods are highly-accurate, their high computational cost and poor scaling with system size routinely necessitates the use of approximate PESs, even for relatively small systems.

Research projects for the spring semester entail the development of neural network representations of potential energy surfaces. Two possible avenues of research are currently envisioned. The first is the construction of surfaces for modeling proton-coupled electron transfer, an important reaction mechanism prevalent in energy applications (e.g., fuel cells, batteries, etc.) and biological processes (e.g., photosynthesis). The second is the development of PESs for ionic liquids, a unique class of materials with myriad applications, in the interest of undertaking a systematic study of their various structural and thermodynamic properties. Although the downstream applications and systems of interest are chemical, the actual research to be done is suitable for an array of majors, including computer science, mathematics, physics, and chemistry majors.
