SOFTWARE, RESEARCH & THE WORLD OF SCENTA few things I’ve been working on
01
Engineering
Software, signals and physical systems made tangible through interaction.
02
Research
Human–computer interaction, sensing and the way people experience technology.
03
Perfumery
Natural materials, scent composition and shared moments of discovery.

Synesthesia
Bringing scent into digital interaction. Custom olfactory displays connect physical materials with multisensory experiences.

Making room for
another sense.
What happens when scent becomes part of an interface? Through Synesthesia, I develop olfactory display prototypes and explore how smell can work alongside visual and auditory feedback.
The work connects embedded systems, physical materials and human–computer interaction.

About the person behind the projects
Curiosity doesn’t
stay in one
discipline.
My work moves between software, laboratory prototypes and the perfume table.
My background in Communication and Information Engineering meets a practical interest in human–computer interaction, physiological sensing and immersive experiences. At Hochschule Rhein-Waal, my work connects research with hands-on prototyping.
Alongside engineering and research, I practise natural perfumery and lead scent workshops through Essentia Resonance. Across these settings, I’m interested in how we understand, interact with and sense the world around us.

The art & science of scent
A different material.
The same curiosity.
Through Essentia Resonance, I work with botanical materials, compose natural perfumes and guide workshops that invite people to explore scent for themselves.
