Personal introduction

I graduated from the University of Waterloo in 1992 with a BASc in Systems Design Engineering.

It informs how I think about design when developing the science-based and risk-based solutions we have been building for our clients for almost two decades which leverage the right combination of data, modelling and visualization. My team specializes in creating IT solutions, with either custom web applications or off-the shelf software like Excel, Anaytica and R, to support risk-informed decision making.
