Title: High Performance Quantum Chemistry Methods for Pharmacology

Speaker: Robert Parrish, SVP QC Ware and Quantum Chemist

Abstract: This talk details recent progress at QC Ware to make high-accuracy quantum chemical workflows fast, robust, and insightful enough for production use in mainline small-molecule ligand discovery programs. We discuss common molecular design workflows such as conformer search, torsion scan, intrinsic reaction coordinate optimization, and transition state optimization, as well as pharmacology-specific workflows for ligand-protein interaction analysis such as the functional group extension of symmetry adapted perturbation theory (F-SAPT). All of these methods are implemented in a brand new quantum chemistry engine specifically optimized for modern NVIDIA GPUs such as A100, and the resultant workflows are generally tractable on order of minutes for ~100 atom systems and on the order of hours for 1000+ atom systems, all with complete modern density functional theory methodology with large Gaussian basis sets possible. The complete toolset is available for general usage by computational or medicinal chemists in the "Promethium" SaaS environment.

Bio: Rob Parrish leads the quantum chemistry technology mission at QC Ware. Rob has spent the bulk of his early career learning how to use many types of hardware to accelerate quantum chemistry codes, including CPUs, GPUs, and even some forays into forthcoming QPUs. He has key interests in getting either more detailed or more complete information out of quantum chemistry codes, as exemplified by his efforts to robustly decompose interaction energies with "F-SAPT" methodology or to provide complete workflows for experimental observables like spectroscopies and conformer distributions. Rob operates under the strong hypothesis that quantum chemistry is imminently due to provide the same digital transformation to chemistry that computational fluid dynamics did for aeronautical engineering, and works daily to be a small part of that transformation.
