After completing his PhD on the application of heuristic choices to sequential choices, Robbie Mochrie took up a post at Heriot-Watt University.  His subsequent work has concentrated on understanding how people engage with, and are able to shape, the economic environment that surrounds them.  This has involved work on the development of economic thought, especially in the 13th century and the Scottish Enlightenment; the historical development of the Scottish churches, understood as economic institutions; and challenges to the development of British credit unions.

For many years, he has provided advice to the Church of Scotland on economic affairs.  From 2012 - 2015, he was Executive Director of the Association for the Study of Religion, Economics and Culture, and more recently, he has provided extensive advice to the board of the Ethical Finance Hub, which will lead to it moving to Heriot-Watt in 2017.
