I grew up in Trinidad and Tobago, where I graduated with a BSc in Maths and Computer Science from the University of the West Indies. After a short (but sufficient!) stint as a COBOL programmer, I came to Scotland where I did MSc and PhD degrees in Computer Science at the University of Edinburgh. My PhD was partly funded through summer jobs at what was then called AT&T Bell Labs, where I worked within an exciting research department which, sadly, no longer exists. After the PhD (phew!) I spent a year on an ERCIM fellowship which allowed me to visit the CROAP group at INRIA in France and the Department for Computation and Information at RAL in England. I then returned to Scotland to become a lecturer at the University of Stirling. I am married to Neil and we have two children, Sharda and Jamie.
I am interested in the use of simulation techniques, including agent-based simulation and virtual worlds, to understand real-world socio-economic phenomena. I also work on the use of interactive simulations and games for science communication, education, and in the development of decision support tools for diverse users. My current projects focus on applications within tree and plant health and agriculture in the UK and in India. In previous work, I investigated the use of formal, mathematical techniques for the development of critical systems. Some specific areas of interest include: the use of theorem-proving tools, particularly those based on higher-order logics and type theory, for formal reasoning about specifications, programming languages and programs; the design and semantics of formal specification languages. I collaborated with Thomas Wilson and Robert Clark, on the Omnibus project. I have also worked with Carron Shankland and Muffy Calder on studying the symbolic semantics of the LOTOS specification language; with Juan Biccaregui on formalizing VDM within the PVS theorem prover; with Elsa Gunter on formalizing the semantics of Standard ML within the HOL theorem prover; with the Lego group at Edinburgh University; and with Edward Farrell of the University of the West Indies.
