 Demet is an urban planner and designer whose research focuses on the built environment and active travel. She completed her bachelor's and master's degrees in Istanbul, Turkey, before completing her PhD in Newcastle in 2021. In her PhD thesis, she investigated the relationship between wayfinding and environmental factors. During her studies in Newcastle and Turkey, Demet participated in research projects investigating the relationship between health, active travel and the environment, including contributing to a REF Impact Case Study-2021. She also engaged in teaching activities and organised workshops, such as an introductory session to the Space Syntax. Before coming to Sheffield, Demet worked as a postgraduate researcher with the Beyond Imagination group at Lancaster University. She is currently working as a postdoctoral researcher at the University of Sheffield on the EPSRC-funded SATURN project (Supporting Active Travel Using Road-lighting at Night), led by Prof Steve Fotios and Dr Jim Uttley in collaboration with the University of Leeds. Their work involves the quantitative analysis of cycling traffic flows and requires the analysis of extensive data sets and night-time lighting measurements.
