Profs @vl_deringer and @fjduarteg have both been busy hosting a Faraday Discussions meeting in Oxford! "Data-Driven Chemistry": exploring #ML and #AI for chemical discovery. You can read about it here: chem.ox.ac.uk/article/farada… @OxfordChemistry @TrinityOxford @Faraday_D #FD_Data

A key idea behind #FD_Data was to build new connections between the molecular and materials #compchem communities – and so it’s jointly chaired by @fjduarteg & myself. Super excited to now see this idea become reality 😀 @Faraday_D
