 Hello, well it's been an extraordinary year for universities, academics have never had so much exposure to the public as researchers and as teachers we've never had to rethink so quickly how to teach in a completely different way. One lesson we have learned is that the already appalling inequalities in our societies have actually increased. There's a broad consensus now that what we have to do is use the experience of the pandemic to reverse that shameful trend to increasing inequalities. Universities are in a prime position in fact to contribute to change for the better. We're in the business of education which is a key force for good in the world and we have the technology, massive reach and newly developed experience in how to teach online. Well this is a good foundation for helping to build a better and fairer world but how best to use what we've learned this last year about digital education. Well my talk will propose that we expand our professional development programs on the large scale to create the communities of practice among professionals that will help them work to reduce inequalities. Academic research must reach all its end users via the professionals who need it in both teaching and in a range of other professional environments and then together we can do that using this new form of teaching online and that's what I look forward to debating with you is these kinds of issues as we all join the even conference. Thank you.
