Washington, D.C. is the source of much inspiration for Roberts. She has developed numerous tours for schools, community groups, and Big Read celebrations highlighting the literary and cultural history of the city. Roberts frequently leads walking tours of the Harlem Renaissance-era Writers in the greater U Street neighborhood. Roberts's research on Walt Whitman’s decade in residence of Washington, DC was featured in The Walt Whitman Quarterly Review, as well as being referenced in subsequent articles in The Washington Post and The Washington Times, features on radio essays on stations WAMU and WPFW, and on panels for Whitman conferences at Rutgers University, the Kennedy Center for the Performing Arts, and at the annual Washington Historical Studies Conference. Roberts was the Coordinator of the city-wide festival in 2005, "DC Celebrates Whitman: 150 Years of Leaves of Grass." Roberts has presented “The Rise of DC’s Black Intelligentsia: Paul Laurence Dunbar and Alice Dunbar-Nelson in LeDroit Park” and “Henry Adams in Lafayette Square” at DC Historical Studies Conferences. Her projects have been supported by the National Endowment for the Arts, The Humanities Council of Washington, DC, the DC Commission on the Arts and Humanities, and the District of Columbia Public Library.
