Katrin Pfeil

Ph.D Student


Katrin’s PhD research is on older adults’ eyewitness performance and investigative interviewing. Her project aims to examine the effectiveness of a new investigative interviewing tool, the Self-Administered Interview (SAI), for older adult witnesses, with respect to its impact on the quality and quantity of the testimony, person identification performance and the susceptibility to suggestions. The PhD is being supervised by Dr. Katrin Müller-Johnson. In support of her studies, Katrin has been awarded a Gates Cambridge Scholarship.
