Deger Ozkaramanli
Deeply inspired by people’s contradictions, I aim to develop new ways with which designers can tackle potential conflicts between virtuous and tempting goals. In this way, design can inform, seduce, or persuade people to choose a course of action that balances choices between virtues and temptations, contributing to their wellbeing.
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.

Doctoral candidate at the TU Delft, Faculty of Industrial Design Engineering
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.
Gregor Waltersdorfer
Doctoral candidate at the University of Luxembourg
Gregor has a background in mechanical engineering and business economics. Since his studies he is interested and engaged in sustainability. In his research he is exploring the role of designers for sustainability.

Simon Jimenez Simon Jimenez
User-centered designer and design researcher www.simonjj.com
Simon Jimenez is a user-centered designer and researcher inspired by human behaviour and flourishing. Simon completed the ‘Integrated Product Design’ master’s programme at the Faculty of Industrial Design Engineering at Delft University of Technology, The Netherlands. As a designer, Simon wants to understand people, and how they interact with and within their environments, in order to create meaningful products and services that add value to people’s lives. Simon is co-editor of the ‘Positive Design Reference Guide’.
Santiago Santiago De Francisco
Santiago studied Industrial Design at Universidad de los Andes in Bogotá, Colombia. After a couple of years working as a concept and product designer, he decided to start the Design for Interaction (DfI) master program at TU Delft. During his working experience he became interested in the importance of people’s behaviors and how those behaviors could be translated into objects, products and services with powerful meanings. Currently he has started a research project about the act of saving, using a piggy bank product as a starting point. This research aims to understand the importance of saving as an experience and its relation to happiness. As part of his graduation project plan, Santiago wants to take this knowledge about the act of saving and implement it in a larger scale.


Emma Kropman
Through my Master Design for Interaction I became fascinated by the opportunities that arise when design and positive psychology are linked. My personal goal is to contribute to the cultivation of a well-being mindset using research and design. For my master thesis I collaborate with DIOPD and social enterprise Gelukskoffer to explore new ways of sharing well-being-related knowledge with young children, which fit the educational content of Gelukskoffer.
Nienke van der Straten
During a bachelor degree in Industrial Design Engineering at the TU Delft, Nienke became fascinated by the power of design. The opportunity to design for human flourishing gives her the motivation to dive into the users’ ind. Coming from the master “Integrated Product Design”, she is now using the positive design thinking to address the problem of lonely elderly in Rotterdam for her graduation.
Chanmi Kim
Chanmi is a graduating student from the masters program, Design for Interaction. She believes that the power of design is in bringing meaningful changes to people’s everyday lives. Chanmi has a genuine interest in the subject of mood. She is now working on her graduation project to uncover the relation between mood and contextual factors in order to design an environment (including product and service) that causes people to have a certain mood, which would lead them to have positive experiences. Chanmi has a background and experience in interior and spatial design and research on cultural differences.
Elske van der Ende
Elske started her bachelor at Industrial Design in 2009 for her a perfect combination of technology and creativity. During her bachelor she found out that she was mostly interested in the user and how they experience products. Design for interaction was the master that fitted this interests. In her master project she is combining her love for animals and people into a project for birdpark Avifauna. The goal of this project is to optimise the experience the visitors have at this park.
Sofia van Oord
My education at IDE (TUDelft) has taught me the responsibility that I have as a designer to put meaningful products (and services) into the world. Products that will enhance the richness of people’s lives, and that will contribute to people’s wellbeing. Currently I am graduating from the master Design for Interaction, on the subject of funerals. I am fascinated by how we have tried to place death out of our lives as much as possible, avoiding interaction with it, turning our funerals into inconvenient things. I will explore new and meaningful ways to cope with funerals.
Minsung Kim
In his previous working experience as a product designer (particularly consumer electronics) in S.Korea, his biggest value was designing a product that makes people smile by means of form giving and interactions. Now, he wants to go beyond his previous expertise, and is enthusiastic about applying experience-driven design approaches, aiming to create positive user experiences. At the master program ‘design for interaction’ of TU Delft, he is working on a graduation thesis project that focuses on facilitating positive commuting experiences for Seoul citizens with smart future buses.
Andreas D’Hollandere
After graduating as a Bachelor within the field of graphic/webdesign and as a Bachelor industrial product design in Belgium, Andreas loved to become more specialised in user interactions and how emotions and moods can be influenced and used within products and experiences. As a graduating student within the master’s program Design for Interaction, Andreas is currently researching the subject of how olfaction can improve the well-being of elderly with dementia in periods of stress. This graduation project gives him the opportunity to research a completely new field within interaction design, olfactory experience design with a strong link to well-being.
Hyunjoo Bae
Hyunjoo Bae has been interested in design for emotion and the color. As a research intern, she has started a project related to mood and colors of the light. She is exploring how people can interact with the lights as a tool to regulate their mood. In future, Hyunjoo would like to make people have more positive experiences in daily life through her design research.
Rushil Jain
Rushil has a background in product design. His fascination with human-product interactions began during his bachelor’s after one of those late night conversations about life, meaning and ‘deep stuff’. His quest for designing meaningful interactions and memorable experiences led him to opt for the Design for Interaction master track at the Delft University of Technology. He’s currently working on his thesis project involving stress and positive psychology.
GYoung is a master student at the design for interaction, IDE, TU Delft. Her project focuses on empowering the children who study in the multicultural backgrounds by positive design education. She studied industrial design and business and technology management in South Korea. She believes in that design can bring positive and meaningful changes to everyday.
