Personal profile

Research interests

My current research on estimating the population size of the children of the working poor in Japan and UK is supported by the Great Britain Sasakawa Foundation Award. This line of research investigates questions surrounding the identification and classification of the poor, such as the new phenomenon, the working poor and their children. This research sits within my broader research interest in understanding growth in advanced economics.

I’ve recently been awarded a best paper award for a paper entitled “Towards the Characterisation of the Ethical Consumer: Conspicuous Ethics”. This research pursuits the identification and characterization of ethical consumption behaviour. Ethical consumers belong to a group of informed consumers, which exhibits rather unusual consumption behaviour. At the heart of this research lies the question of what motivates ethical consumption and is there more than just an ideology to it?

I’ve also worked in the intersection of economics with finances, and I currently run a special edition on “financial economics” of the International Journal of Financial Studies. Most of my work concentrates around questions related to the financing of the firm when financial markets are incomplete. I have mostly applied techniques from differential topology, differential geometry, and catastrophe theory to the study of financial economic equilibrium.

As a trained mathematician I do also work in mathematics. My main interest is in the field of dynamical systems, in particular non-smooth dynamical systems defined by a set of ordinary differential equations with discontinuous right hand side. I’m currently working on a theory of exponential asymptotic stability of periodic orbits. This requires defining contraction metrics on smooth manifolds using Riemanian  metrics. Applications of that work is mainly in the field of biomechanics where I study lateral stability of human motion and out of equilibrium dynamics of seasonal models such as those encountered in the farming industry

Approach to teaching

I have over 10 years of extensive teaching experience at various top higher education institutions in the UK such as University College London (Department of Statistical Sciences), University of York (Department of economics and related studies), University of Sussex (Department of Mathematics, Department of Economics). My teaching is research informed and students should expect to be introduced to latest developments in research in their classes. I’ve been awarded several Excellent Teaching Awards for teaching mathematics to a wide range of interdisciplinary audiences including students from management, economics, finance, politics, mathematics, and philosophy. I’ve designed a very successfully running module called  “Game Theory in Economics, Finance, and Business” which introduces students to key strategic interaction concepts and allows them to work on computer simulations of real world problems.
