I am a Reader in Software Engineering and Deputy Head of Department (Education) at the Department of Informatics at King's College London (see what student's have to say) and a Visiting Scientist at the Francis Crick Institute. I am a member of the Software Systems (SSY) group. I also direct MDENet: the expert network for model-driven engineering.

I came here from Lancaster University, UK, where I was a Marie-Curie Fellow. Before that, I had been a PhD student and research associate with Technische Universität Dresden, Germany.

In 2007, I received my doctoral degree (Dr. rer. nat.) from Technische Universität Dresden, Germany. My doctoral thesis was in the area of non-functional properties of component-based systems and was awarded summa cum laude.

Outside of work, I am most likely to be found a) in front of a book reading stories (well, anything, actually), or b) in rehearsals working on some new theatre play.
