Students will be invited to attend a number of optional online meetings. There will be four sessions for each cohort and will focus primarily on questions arising from the most recent module or on a specific topic from invited experts. Acknowledging the worldwide location of our students, we aim to offer two dates/times for each session, and recordings of the sessions will be made available for those who are unable to attend. The online sessions also give students the opportunity to get to know their fellow students better and build a network of contacts.
