Professor Dr J. (Jan) Jonker is a specialist in sustainable entrepreneurship, strategy and business modelling. Until recently (Spring 2021), he was employed as a professor at the Nijmegen School of Management (NSM) at the Radboud University Nijmegen (RU – Holland).

He also held the Chair d’ Excellence Pierre de Fermat at the Toulouse Business School (TBS) in Toulouse (France) and was the Chairholder of the Chair Emilie Francqui at the Free University in Brussels, Belgium. Professor Jonker’s research interests are explicitly developing strategies for sustainability and circularity related to new business concepts and business models.

Within this focus, he explores how to shape systemic change and transformation leading to organising (inter) organisational sustainability. Thus far, he has written and co-written 35 books, published over 150 articles and provided numerous contributions to blogs, talk shows and radio programs.

He retired from active academic life in Spring 2021 and has gone back to providing consultancy support often based on actual yet applied research. He remains an often-solicited international speaker. If he doesn't work, he cooks, buys wine and continues restoring his 16th-century house in the South of France. Professor Jonker can be reached at janjonker@me.com
