In the late 1980s after postgraduate studies at the University of Lancaster, Markus emigrated to work at the University of Otago, Dunedin, New Zealand. Previously Professor of Accounting at Otago, he moved to Canterbury in 2006. Markus studied accounting and finance at both Middlesex and at Lancaster.
Driven by a boyhood love of the outdoors, nature, and a sense of justice, over the past 25 years he has developed a critical research agenda investigating the social and environmental impacts of organisations, and the means by which they account for and communicate those impacts. Since his first publication in 1991 in a special issue on 'Green Accounting', Markus has sought to understand and critique modern organisations' relationships with the natural environment.
He has published over 80 papers and book chapters, and his work is widely cited in the field. His work has appeared in Accounting, Organizations & Society, Accounting, Auditing and Accountability Journal, Critical Perspectives on Accounting, Management Accounting Research, Accounting and Business Research, Organization, Journal of Business Ethics, and Organization & Environment.
In 2009, he and his co-authors received the Mary Parker Follet award for best paper in volume 22 of Accounting, Auditing and Accountability Journal. The paper had previously been recognised with the Organizations and Natural Environment (ONE) division award at the 2008 Academy of Management Meetings.
