 Essentially, a lot of what we're doing is about how to take things into health services or into health systems, how to create health systems to deliver many of the products and technologies that many of our research colleagues are developing. And essentially a lot of this health services or health systems research has to tackle with these broad generic questions. And we often, and to tackle some of the broad and generic questions we need to engage with a range of disciplines. And often I think, as myself is coming from a very clinical background, we often think that if we've developed the clinical product, then that's surely is our job done. And if it's obviously works in a clinical trial or something, then, then isn't it logical that it will just get into practice. But we've known for many years that that doesn't happen, and that that kind of simple logical argument doesn't work. So, this broad field of health policy and systems research, which has always been there, one sense, but has become much more prominent over the last years is now the arena in which disciplines are coming together. We've got these very interesting examples of work today which demonstrates some of the challenges. In this seminar series, we're actually trying to highlight some of these challenges and how these different disciplines come together to create solutions or identify problems, and also show how different methods can enhance what we do when brought together. And particularly when it's in making new connections, but as Oxford, as everybody knows, amongst many other areas of work has these enormous or normally successful overseas programs, or, but often, often we're not so well connected. And when it comes to interdisciplinary research, maybe that's something that we could take advantage of.
