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

Profile picture DIOPD website (cropped ID studiolab) Boudewijn Boon
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.
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.
Lisa Wiese
Lisa is an external PhD candidate at TU Delft based in Berlin. Her background is in psychology, statistics and neuroscience. For the last ten years, she’s been conducting user research for eBay EU and helped shaping the user experience across different eBay subsidiaries (currently at brands4friends). Her PhD research at TU Delft focusses on the development of measurement instruments to assess products’ contribution to well-being.
Mafalda Casais
Mafalda has a background in illustration, graphic design and industrial design (MSc). Her PhD research at TU Delft focuses on the symbolic value of household products, its influence on personal values, behaviour and self-expression and its contribution to subjective well-being of the user.

Master students

Hazal Ertürkan
Positive design acquainted me with new ways to shape the future as a designer. I’ve gained a different perspective in addition to my industrial design background through DFI Master Programme. I became passionate to create meaningful experiences through interactions. My recent study is based on the Tiny Task concept, which aims to transform happiness enhancing activities into small tasks. The goal of the project is to adopt the concept into office environments to stimulate work engagement and increase happiness of employees.
Jin Li 
Jin Li is a Design for Interaction student in TU Delft. With a background of product design in China, she started to explore the possibilities of positive design. She is always fascinated about creating special gifts and she believes that gift has more potential than bringing happiness to others. Her graduation project is to develop an online gift selecting tool for gift givers to find out what will contribute to their recipient’s well-being.
Maurizio Filippi
Maurizio is a Design for Interaction student at the Delft University of Technology. Previously, he has studied Industrial Design at Politecnico di Milano and at Lahti University in Finland. He believes that the very essence of designing lies in awareness, reflection, critical thinking and attention to detail. In his everyday life he tries to pursue those virtues in order to create products that bring quality into people’s lives.
Pelin Esnaf
As a student who has an industrial product design background from an art university, Pelin is fascinated by the freedom that art and painting gives. Doing research on emotion, mood and the motivation behind people’s behavior was the missing piece in her bachelor studies. She finds the profoundness which art gives in the science of behaviour and mind. She is now working on a research internship project about mood and sleep. Her aim is to identify products,objects,services involved in the fifteen strategies to regulate mood and to hopefully give inspiration to designers and students.
