Our Team


Anna_Pohlmeyer Anna Pohlmeyer
Anna Pohlmeyer’s background is in psychology (Humboldt University Berlin). Furthermore, she completed her PhD research in engineering design at TU Berlin and the University of Luxembourg. Her thesis focused on early phases of product development in the design of human-technology interaction. Prior to her doctoral studies, she worked at MIT AgeLab on ideas and technologies that can improve quality of life across the lifespan. As assistant professor at TU Delft, she investigates theoretical and empirical aspects of design-mediated well-being.
Pieter Desmet
Desmet introduced cognitive emotion theory to the domain of design research, and is board member of the International Design and Emotion Society. Desmet was recently awarded a five year personal grant for research that aims to understand the nuances of positive emotions in human-product interactions.
Deger Ozkaramanli
Deger studied Design for Interaction at Delft University of Technology and received an M.Sc. degree with a thesis focusing on designing for sustainable eating habits using emotional dilemmas as a starting point. She continued to investigate the design-relevance of emotional dilemmas in her PhD project, which was finalised in March 2017. In this project, she developed tools and methods that can support designers in using emotional dilemmas as valuable starting points for user-centred design processes. Example domains in which this approach has so far been implemented include sustainability, physical and mental wellbeing, social play and more. Deger is a member of Delft Institute of Positive Design, and currently, she continues her research on dilemma-driven design at the University of Liverpool (February 2016 – present). See her personal webpage for more information.
yoon Jay Yoon
Jay Yoon is a PhD candidate at Industrial Design Engineering of TU Delft. He has a background in industrial design and computer science. His research focuses on emotion-driven design, mainly concerning how understanding nuances of positive emotions can contribute to a design process. He has been developing design tools and techniques aiming to assist designers to be aware of differentiated aspects between distinct positive emotion types. He is currently working on identifying the opportunities to work with the awareness of nuances of positive emotions.

Post-doc researchers

Haian Xue
Haian is currently working at IDE and DIOPD as a post-doc researcher on the Design for Mood Regulation research project. He has a background in Industrial Design and acquired his Doctor of Arts (Finnish equivalent of PhD in Design) from Aalto University in Helsinki. In past ten years, he has lived and worked in Finland, the UK, and the USA as a design researcher and teacher. His research interests stand at the intersections of design, experience, and strategy. In addition, he also finds his (spare time) passion in philosophy, physics and history.
Steven Fokkinga
Fokkinga introduced the possibility of involving negative emotion in product interaction, thus unlocking a whole new range of potentially enjoyable product experiences for designers. He explored and formalized these insights into an approach that leads to richer, more meaningful product-user experiences.

Doctoral candidates

Boudewijn is interested in how design can play a role in shaping the ways people live their lives. During his master thesis (MSc Industrial Ecology) and his work as a research assistant for Pieter Desmet, this interest was reflected in his research on how design can facilitate ‘the good life within ecological means’. As a PhD candidate he is currently exploring how design can engage children with cancer in physical play and thereby stimulate their physical development.
Pelin Esnaf
Pelin is one of the three PhD candidates working for the Design for Mood Regulation research project. She has a background in industrial product design and holds a masters’ degree from TU Delft, Design for Interaction programme. She worked on a research internship project about mood & sleep and identified the products involved in the fifteen strategies to regulate mood. Then, in her master thesis, she focused on the empathic abilities of design students. Currently, she is exploring the relation between mood & performance. Her aim is to make the education better and to hopefully give inspiration to students, educators and designers.
Alev Sonmez (Plamena Karova)
Alev (Plamena) is a Ph.D. candidate at Industrial Design Engineering faculty of TU Delft. As a part of ‘Design for Mood Regulation” project, her research focuses on mood phenomenon from a collective perspective. She is interested in how moods function and are manifested in group settings, how individuals’ moods affect the team ‘vibe’ and how mood-sensitive design can improve interactions and performance of work groups. Alev studied in Industrial Design (BSc) at METU and pursued her master’s degree in Design for Interaction at TU Delft. Besides positive design, she is interested in service design, behaviour change, speculative design, design for animals, and she enjoys philosophical discussions and dancing.
Makiko Higashi
Makiko is a multidisciplinary designer (MA Royal College of Art) + researcher (MSc HCI, University College London), currently working on Design for Mood Regulation project at DIOP. Having a strong interest in the area around Psychological Wellbeing and Design Innovation, She integrates a critical and speculative design approach with a more empirically driven and principled manner in her research and creative process. With the experiences in both academia and industry, her strength is also translating research into sustainable design impact, with practical output.
Katja Thoring
Katja is Industrial Designer with a Master degree (Dipl.-Des.) from the University of the Arts Berlin. She is currently professor at Anhalt University of Applied Sciences in Dessau, where she teaches the Product Design Foundation class and Research Methods courses on Bachelor and Master level. She is also experienced in coaching design thinking and creativity techniques in various organizations. Her PhD topic ‚Creative Space‘ is focusing on the intersection of Design and Architecture, analyzing the influence of the physical environment on the creative work process of designers and design students. Moreover, she investigates the possibilities of new technologies for design research in general and emotion measurement in particular.
