Mari Sako's main areas of expertise include global strategy, comparative institutional analysis, outsourcing and offshoring, and professional services.
Her most recent work has focused on business and professional services and on outsourcing. Mari's work on business services in the UK has attracted the interest of UK policy makers.
Her research on the globalisation of legal services and its impact on the professions has led to her becoming member of the UK Legal Services Board Research Strategy Group, and member of the advisory board of Thomson Reuters Legal Executive Institute. During 2011-12, she was President of the Society for the Advancement of Socio-Economics (SASE). Mari also earlier made a significant contribution to the understanding of the Japanese economy and Japanese firms. In the 1990s and 2000s, she was a researcher for the MIT International Motor Vehicle Program (IMVP), which gave her a valuable opportunity to be out in the field, observing and interviewing managers and workers at automakers and their suppliers in Japan, Europe and the USA. Insights from the fieldwork to understand lean production and quality control are also informing her more recent work on what professionals such as lawyers do. Her research has been published in the form of five books and numerous journal articles.

Arising from her work on global legal services markets, Mari is a member of the Research Strategy Group of the UK Legal Services Board . She is also on the advisory board of Thomson Reuter’s Legal Executive Institute, which aims to create thought leadership on the impact of technology and regulation on legal services. Mari is frequently called upon to give evidence and keynote speeches at conferences, including at the Law Society of England and Wales, International Bar Association, and General Counsel Netherlands.

Mari teaches Global Strategy and Global Rules of the Game on the Executive MBA Programme.
She also teaches on other degree programmes including the Diploma in Global Business, the Diploma in Strategy and Innovation, and the MSc in Major Programme Management. Her teaching for custom executive programmes has been for professional services firms.
Mari also supervises doctoral students and considers this an important part of what she does as it straddles her research and teaching interests.
Her teaching philosophy is to create a stimulating and memorable learning environment for students in what is typically a very international environment. Her teaching focuses on the challenges of global business leaders face, such as non-market issues of risk and reputation that arise from interactions not only with competitors, suppliers, and customers, but also from the state and non-government organisations.
Mari has also written teaching cases, including a case on Evalueserve, an India-based knowledge process outsourcing company and on the reputational challenges of government outsourcing. Please contact her for permission to use the cases.
