Chris Stolwijk led various large-scale research projects, including a series of document catalogues and the Van Gogh Letter Project, and cooperated on a number of international exhibitions, such as Paul Gaugiun: the Breakthrough to Modernity (2009-2010) and Van Gogh & Nature (2015). The focus of his input lies in West-European paintings from the period 1800-1940 with a specific interest for the life and works of Vincent van Gogh and his inner circle, the history of art history, the history of art collecting, the social economic aspects of art and the skill of artistry including the professionalisation of the art trade, museification and digital art history. This interest manifested itself in numerous publications and other contributions.
