Research

 

I’m a researcher by training. I obtained my PhD in Computer Science from the University of Copenhagen in October ‘21. The things I find most interesting often relate to digital fabrication, wearable devices, and ubiquitous computing. Here’s a selection of the projects I’ve been involved with, for more check out the Research tab.

Print-and-Play Fabrication

This is my PhD dissertation. I introduced Print-and-Play Fabrication as a digital fabrication model where interactive devices (i.e., devices that can sense, process, and respond to user’s interactions) are printed using consumer-level fabrication machines instead of being assembled by their designers. You can read a bit more here.

 

AirTouch

AirTouch is a technique I developed with the help of my co-authors to create devices that can sense touch interactions on 3D-printed objects using air (get the name now?). I used principles of fluid dynamics to develop internal structures that, when the object is connected to a source of air, the internal air pressure inside the object would vary in unique ways depending where it’s being touched.

AirLogic

AirTouch is a technique I developed with the help of my co-authors to create electronics-free, self-contained devices. Instead of using electronics and batteries, these devices use air to calculate computational logic in 3D-printed objects (I bet the name makes sense now). I got inspired by very old and almost forgotten research from the 1960s and some basic fluid dynamics to create a set of components, or widgets, to create self-contained devices that require no electronics to function.


Projects

 

Somehow, I find the time to work on personal projects. These are the most recent ones I’ve done/the ones I’m most proud of. All the code for these projects, and others is on my Github profile.

Arda

Arda is the name of the fictional planet where Middle-earth is on, but in this case it’s a project to help the construction of laser-cut maps (left) by extracting the different “layers” that compose a map tile, and creating vector files to send to a laser cutter.

 

Teleri

The Teleri are Middle Earth’s greatest singers (you might start to notice there’s a theme on how I name my personal projects). This tool helps me discover new music by searching through aggregating websites(e.g., Metacritic, Pitchfork) and predicting if I would like a given album based on the content of my library, playlists, and songs I love.
