# Biographical Sketch

I joined the University of Oxford in 2006, where I am currently Professor of Engineering Science and a Tutorial Fellow in Worcester College, Oxford. Since 2015, I am EPSRC Fellow and Director of the EPSRC & BBSRC Centre for Doctoral training in Synthetic Biology. I obtained an MA/MEng degree in Electrical and Information Sciences from the University of Cambridge, U.K., as a member of Robinson College in 2000. In 2005 I completed a PhD in Control and Dynamical Systems at the California Institute of Technology, with a PhD Minor in Aeronautics. My thesis was on "Scalable Analysis of Nonlinear Systems Using Convex Optimization". In 2005 I held a short David Crighton Fellowship at the University of Cambridge and a postdoctoral fellowship at the California Institute of Technology. In 2015 I was awarded the European Control Award for my contributions to robustness analysis and applications to networked control systems and systems biology and the O. Hugo Schuck Best Paper Award. I serve regularly on Technical Programme Committees for conferences, and I am associate editor for *Automatica* and *IEEE Transactions on Automatic Control*.
