This PhD is industry-funded for four years. The student stipend will be £19,277 per year (this is the EPSRC stipend plus a top-up equal to that normally associated with an EPSRC ICASE award). Extensive funding for travel (both to visit the industrial partner and to attend international conferences) is also included. This PhD also includes funding for PhD fees (for UK and EU students only). Extensive interaction with the industry partner, who have data from these novel DAS systems, is anticipated. The start date is to be agreed, but could be immediate.
