Her first monograph, titled "Nationalists Who Feared the Nation: Adriatic Multi-Nationalism in Habsburg Dalmatia, Trieste, and Venice," is forthcoming with Stanford University Press in 2011. Professor Reill has been awarded numerous research grants for her work in the Italian and Balkan peninsulas. Currently she is beginning a new monograph investigating the Fiume/Rijeka crisis in 1919-1920, commonly believed to be one of the formative experiences in the development of Italian fascism.
