Karen’s research expertise is in Polish Jewish history and the history of the Holocaust. Her first book, The House at Ujazdowskie 16: Jewish Families in Warsaw after the Holocaust (Indiana University Press, 2013), is a microhistory of Jewish integration in postwar Poland focusing on ten families who were neighbors in an apartment building in Warsaw.
She is currently working on a second book about Jewish booksellers and publishers of Polish literature in nineteenth-century Warsaw.
She is also completing a secondary project examining the spread of information among Jews within Nazi-occupied Europe during the earliest stages of the Holocaust in 1941 and 1942. Previous to her doctoral studies, Karen published numerous articles in the New York-based Forward newspaper about Jewish life in contemporary Poland.
