I am a design researcher who works on the human-centered vexperience design of personal health technologies. Currently, I am an Assistant Professor at the University of Twente, Interaction Design Research Group. I am passionate about research and design of human-centred technology experiences. I have an Industrial Design academic background.

I have a PhD degree from Middle East Technical University (METU) of Turkey. I worked as a researcher at METU, Department of Industrial Design and Product Usability Testing Unit (UTEST) for several years. I also worked as an assistant professor at TOBB University of Economics and Technology (Ankara, Turkey), where I was granted two TUBITAK (Scientific and Technological Research Council of Turkey) Research Fundings. During my PhD, I was granted with Fulbright PhD Student Scholarship, and I studied at Carnegie Mellon University, Human-Computer Interaction Institute (USA).

Experience and human-centred design are at the core of my expertise. In my previous empirical works, I worked on the effects of personal health technologies (e.g personal informatics and self-tracking tools) on our behaviour. I explore how interaction design practices could create socially acceptable health behaviour tools and (can) change health behaviour. Currently, I am interested in the roles of (data) interaction design in self-tracking of physical activity and sports. My work combines physiology and psychology with interaction design in understanding and designing meaningful (data) interactions for engagement in physical activity and sports. Recently, I aim to answer the following research questions:

  • What are the current user practices of meaningful (data) interactions in personal health technologies?
  • How can we transform this knowledge to novel personal health technologies?
  • What should be the role of designers in this transformation?

The courses that I’ve been giving mostly focus on human-centred design, interaction design, creativity and design thinking, and design for behaviour change. I am currently contributing to the Industrial Design Engineering at both Bachelor’s and Master’s levels. I am also involved in Creativity and Design Thinking course at Twente Graduate School. I regularly supervise Bachelor’s and Master’s students. In 2021, I received my Senior University Teaching Qualification, for which I developed educational tools for peer-testing in user experience courses.

We live in a data-driven world, which triggers the way research in health technology is carried out. This fact results in the evolution of digital health technologies which become more and more data-driven and neglects the way people experience their health data. As an expert researcher of experience design, I work on discovering ways to better understand people’s experiences with (digital health) data (see this paper). Meanwhile, I work on developing tools and research projects to make developments in this field more tangible (see this chapter) and long-lasting (see this paper), and contribute to people’s data sensemaking practices.

Currently, I am interested in the roles of (data) interaction design in health and wellbeing, especially in self-tracking of physical activity and sports. My work combines physiology and psychology with interaction design in understanding and designing meaningful (data) interactions for engagement in physical activity and sports.
