Neural graph representation learning with application to chemistry
… First, we seek to automate the prediction of organic reaction outcomes. The previous solution utilizes reaction templates to limit the space, but it suffers from coverage and efficiency issues due to its discrete nature. We propose a template-free approach to efficiently explore the space of …

Computational Analysis of Molecules and Chemical Reactions from Cheminformatic Databases
A large number of organic reactions feature post-transition state bifurcations. Selectivities in such reactions are difficult to analyse because they cannot be determined by comparing the energies of competing transition states. Molecular dynamics approaches can provide answers but are …

Mechanism and application of Lewis and Brønsted acid effects in organotransition metal catalysis
… with a focus on method development for catalytic reaction applications in organic synthesis. The unifying theme throughout the research is the development of rational design principles for cooperative catalysis through both mechanistic and empirical study. Cooperative catalysis – in which multiple …
