I am associate professor in the Human Media Interaction Group. Before being at the UT I spent a few years in Nijmegen, Radboud University, as a postdoc, and at the TU München for studying computer science and doing a PhD.

Organisaties

My current main research interest is wearable technology, and especially haptic stimulation. Furthermore, I am interested in design processes for creative and human centered design of products that involve technology. 
In the past I worked on Formal Methods in Computer Science, especially model checking in the modal mu-calculus, and modelling and verification of embedded systems.

Onderzoeksprofielen

I am mainly involved in the bachelor programme Creative Technology, participating in the curriculum committee in the early years, and setting up the programming line of the programme.  
As a research line in education I am exploring how to use tinkering in academic teaching to stimulate ownership and reflection.

Vakken collegejaar 2024/2025

Vakken in het huidig collegejaar worden toegevoegd op het moment dat zij definitief zijn in het Osiris systeem. Daarom kan het zijn dat de lijst nog niet compleet is voor het gehele collegejaar.

Vakken collegejaar 2023/2024

Wearable Breathing Trainer: measuring and coaching for children with dysfunctional breathing patterns 
Together with Geke Ludden (UT) , Hellen van Rees (textile and fashion designer), Boony Thio (MST), Pascal Keijzer (MST), Jean Driezzen (ZGT), Eliza Bottenberg (Saxion).
We will develop a robotic vest in a child design and equipped with suitable sensors and actuators, that will help children with, e.g., asthma to do breathing exercises at home. 
(starting january 2019)
Financed by The Pioneers in Healthcare Innovation Fund 2018

I am coordinator of the project WEAFING (weafing.eu) that has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 825232, starting January 2019. 
Here, textile actuators ("knitted muscles") are developed from electroactive polymer and processed into textiles. Goal is to develop garments that provide haptic stimulation. The application range is huge, ranging from navigation applications to stress reduction garments, from movement training for work, sports or wellness to extended experience in gaming.
With Cedric PlesseEdwin JagerNils-Krister PerssonEdwin DertienJan van ErpMartin van den Berg (elitac), Marius Janta (WT), and Marco Raaben.

In the project "Textile Reflexes" I developed, together with Hellen van Rees (fashion and textile designer) and Geke Ludden (interaction designer), a robotic vest that gives haptic feedback when slouching. This project was funded within the H2020 project WearSustain.
See a description at the wearable robotics lab.
