It is a very part-time assignment, though I will give at least one guest lecture/seminar a year to staff/students or the general public. The first of these will be on Monday 9 March at the Belfast campus of Ulster University. I understand that it is already pretty heavily subscribed, which is encouraging.
This has no effect on my day job in Brussels, other than helping to strengthen links between academe and the private sector in public affairs. Colleagues at work have been gratifyingly positive about it. I may start putting "Professor" on my business cards, though!
