Application of Deep Learning in Molecular Docking

​Development of a physics-based deep learning network to calculate binding free energies of small protein-ligand complexes in an implicit solvent model. We build our model based on a deep learning framework called Deepchem, a python library mainly used in drug discovery processes.

Computational Study of Binding the Novel Coronavirus to the Human ACE2 Receptor

Evaluation of the potential of a molecular mechanics generalized Born surface area (MMGB/SA) approach to estimate the binding free energy between the SARS-CoV-2 spike receptor-binding domain (wild type and mutants) and the human ACE2 receptor.

Global Optimization of Biomolecular Surfaces

Optimization of atomic radii in an implicit solvent model to obtain close agreement with experimental results in terms of calculating electrostatic binding free energies. The underlying massively parallel optimization method, VTDIRECT95, runs on Virginia Tech clusters.
