I joined UCL in 2022 as an Associate Professor in Applied Mathematics. From 2007–2022 I held academic positions at Queen Mary University of London (QMUL) and, since 2017, I am also an External Fellow of the London Mathematical Laboratory. I have a D.Phil. in Theoretical Physics from the University of Oxford and carried out postdoctoral research at the Forschungszentrum Jülich and the Universität des Saarlandes.
My interests are focused on stochastic nonequilibrium processes including:
 interacting particle systems, large deviations, fluctuation relations
 applications, e.g., traffic, econophysics, biological modelling.
