Physics has long been a male-dominated subject. To fulfil the department's scientific mission, it is vital that we use the full potential of the population and redress that imbalance. Since 2010, the department has been developing a portfolio of new and existing actions to improve the employment conditions and practice for all staff and students. Good practice benefits everyone, but disproportionately benefits women. These actions, and the critical assessment that led to them, are described in our application for an Athena Swan Silver Award.
