It's very important that we (Mel and Ronan) be able to get in touch with you directly. Email is the usual medium, so please let the Programme Director and Administrator know immediately if you change your email address. It’s much better to use a personal email address that won’t change for the duration of your studies.
You will also be given a UCD email address. UCD may use this for formal communication with you, and you are expected/obliged to read email sent to you at this address. See here for more details.
