The second annual Materials & Molecular Modelling (MMM) Hub Conference and User Meeting took place on 3-4 September. Many excellent talks demonstrated how the computational resources provided by the MMM Hub are used to tackle challenges in many areas of biological, chemical, and physical research. This was also illustrated by more than 50 posters, spanning a wide range of topics and computational techniques. One of the two poster prizes went to Fabian, who presented “A machine learning based interatomic potential for hexagonal boron nitride”. Well done!
