Biography

I am Professor of Finance specialising in quantitative finance. Before joining Keele I was a Lecturer at University of Stirling and University of Wales, Cardiff, Associate Professor at University of Nottingham and a Professor Finance at University of Salford.

I studied for my undergraduate degree at University College London and for my PhD at City University Business School now known as Cass Business School. Prior to joining academia, I worked as a Senior Investment Analyst at Abbey Life Investment Services.

Research and scholarship

My current research interests include:

  • Modelling negative yields and the terms structure of interest rates
  • Robustness of option pricing models
  • Estimation of market risk under extreme market conditions
  • Vine copula to estimate market risk
  • Impact of political connections on firm activity
  • Comparing the performance of Islamic banks with conventional banks

I would welcome applications from students in the general areas of risk management, time series analysis, option pricing and yield curve modelling.

Teaching

I have taught extensively both at home and abroad. At home I have taught for a wide range of universities including, City University, University of Stirling, University of Wales, Cardiff, University of Nottingham, University of Nottingham Malaysia, University of Southampton, Kingston University and University of Salford. I have taught from first year undergraduates at one end to PhD students at the other. I have taught to small classes of three or four to classes of two hundred or more. I am able to teach across all areas of Finance from the very basic first year Finance modules to the advanced PhD Mathematical Finance module. I have over twenty years of executive teaching experience. I have taught to executives in the City of London, Luxembourg, Dubai, Malaysia and Singapore. I have taught a wide range of subjects at executive level including Islamic Finance, Derivatives, Risk Management, Time Series, Econometrics and Term Structure models.

I have completed one year Team Mastery programme to become a qualified coach. This course involved indepth study of modern coaching techniques and their application in a team based entrepreneurial setting. In this setting, all learning is experiential and student led with the traditional lectures abandoned and student form themselves into teams to start a company. In the process of developing a viable company students meet the learning outcomes of the modules and hence of the course. As part of the one year programme, I visited different institutions in the UK and Europe including Finland and Switzerland to learn how modern coaching techniques are applied differently in different institutions to meet the same outcome.
