For over twenty years DuBois has been engaged in various aspects of the art world, working in retail gallery and museum settings, teaching university-level art history courses, producing essays as an independent scholar and lecturing extensively in cities including New York, Seattle, Boston and Providence. She co-authored the catalogue raisonné on Jacob Lawrence and the monograph, Jacob Lawrence: Over the Line, which was awarded The George Wittenborn Award for Excellence in Art Publications. A Jacob Lawrence retrospective based on this publication was organized by the Phillips Collection in Washington D.C. and toured nationally for over two years. Most recently, DuBois was a contributing author to American Paintings, Watercolors, Pastels, and Stained Glass at Harvard (New Haven: Yale University Press, 2008) and wrote an essay for a solo exhibition for Charles Seliger, titled “The Structure of Becoming” – Charles Seliger’s Expressions of Complexity (New York: Michael Rosenfeld Gallery, 2008).

In addition to being an independent scholar, DuBois has a Certificate in Appraisal Studies in Art and Antiques from the Rhode Island School of Design, in conjunction with the American Society of Appraisers. She is educated in Personal Property Valuation, Art and the Law and is up to date on Uniform Standards of Professional Appraisal Practices. DuBois is regularly invited back to the Rhode Island School of Design to lecture on various topics in art history and the art market for the appraisal studies program.
