The Anglo-French Physical Acoustics Conference (AFPAC) 2020 meeting at Selsdon Park was held from 15 to 17 January 2020. As it is now a very recognisable characteristic of this meeting, the range of acoustics/ultrasound topics covered was quite impressive. Over the three days of the conference, 40 high quality papers were presented by speakers at different stages of their research careers, from those still at the early stages of their PhD projects, to well-established world leaders in the field. From amongst the latter category we had seven invited speakers: Carmel Moran (translational ultrasound); Brian Fowlkes (bubbles and droplets in medical applications); Ana Namburete (ultrasound imaging of foetal brain development); Richard Craster (elastic meta-materials); Vincent Pagneux (observation of topological edge waves); Larry Crum (role of cavitation in therapeutic ultrasound) and Quentin Grimal (ultrasound evaluation of bone fragility). We were all very grateful for the knowledge and experience imparted by our invited speakers to all those present. The first day of the meeting was organised jointly with the Medical Physics Group of the IOP, and we would like to say a big thank you to Professor Sarah Bohndiek for her help with the organisation of the event. We are also grateful to Verasonics Ltd. and Carlos Faustmann for their sponsorship of the meeting.
