Dr Hannah Dee

Senior Lecturer

Contact Details


Hannah has a BSc in Cognitive Science (1996), an MA in Philosophy (1998) and a PhD in Computing (2005) all from the University of Leeds. Her research areas are applied computer vision; the detection of shadows and reasoning about shadows; and student attitudes to the study of computer science. She has held postdoctoral positions in Grenoble (France), Leeds, and Kingston upon Thames. She is also a women in computing activist: she founded the BCSWomen Lovelace Colloquium, a national conference for women undergraduates in computer science, and is still deputy chair. She has been on the committee of BCSWomen since 2007.
