The Royal Society hosts a program of scientific meetings each year with the aim to bring together scientists from around the world to present and discuss new research in all areas of science. Each meeting is organised by leaders in the field, using their expertise to ensure the key topics are covered. The Royal Society contributes to travel and expenses for the meeting and provides logistical support. Proposals are invited from any UK-based researcher. Many meetings have co-organizers from outside the UK. The deadline for scientific meeting proposals is 01 April 2020. More
