The Drexel Research Discovery Dissertations & Theses collection includes theses and dissertations submitted electronically, in addition to scanned copies of earlier theses. You can search only for theses and dissertations using the Dissertations & Theses search. To find theses from a single department, after your initial search, use the DU units filter or go to a specific DU unit to navigate to the department and search only its publications. From the specific unit, remember to select the Resource Type filters for both Dissertations and Theses (2 check marks) in the sidebar. If the results are still too broad, you may wish to further filter by a sub-unit or date. More information about Drexel Dissertations and Theses.
