Student Presentations

 All doctoral students are expected to deliver presentations at meetings of national or international professional societies. The research group covers the cost of participation, however, students are encouraged to apply for travel grants to reduce the impact on the group budget. Recent presentations delivered by student members of the Orazem group are shown below with the presenting student in bold font.
