Although an economist and mathematician by training, Professor Choudhury has contributed to the associated fields of finance, sociology and the philosophy of economics (participative dynamics, circular causation, ethics and well-being). He is the founder of the epistemic field of Tawhid (monotheistic law) and the Islamic socio-scientific world-system, with extensive theoretical and applied studies in the corresponding fields of economics, society and science. In all these areas his focus for much of his career has been in the area of participatory dynamics related to diverse problems of economics, finance, and socio-scientific systems studied in the epistemic worldview. He taught economics for twenty-two years until his retirement from Cape Breton University, Nova Scotia, Canada, in 2008. He graduated with his Masters and Ph.D. from the University of Toronto in 1977. Professor Dr. Masudul Alam Choudhury presently lectures on the Post-Graduate Program in Islamic Economics and Finance in the Faculty of Economics, Trisakti University, Jakarta, Indonesia. He offers Ph.D. level subjects, namely, Islamic Epistemology of Economics and Finance; Islamic Microeconomic Theory; Islamic Macroeconomic Theory; Advanced Islamic Economics and Finance; and Islamic Comparative Development Studies. He is also the Editor-in-Chief of the Journal of Critical Realism in Socio-Economics (JOCRISE). This international journal is published by the University of Darussalam Press, Gontor, Indonesia. Professor Choudhury's most recent publication is the Handbook of Islamic Philosophy of Science: Economics, Society, and Science (2024, Springer Nature).
