Profile
I'm a PhD student at TECO since 2024, working on the OpenEarables and the JuBot Project. During my Masters's thesis, I enhanced OpenEarable by developing OpenEarable ExG, an extension that enables the sensing of biopotentials such as EEG and EOG.
Since then, my current research focuses on harnessing the rich potential of biopotentials using wearables, to gain deeper insights into brain and body activity.
If you are interested in a thesis working on biopotential-sensing for health and HCI (EEG, EOG, EMG), embedded machine learning, wearables, innovative iOS / iPadOS apps, even if there's none listed below, please just give me a shout!

Projects
Finger-to-Ear ECG
Finger-to-Ear ECG explores earbud-based cardiac monitoring by combining an in-ear electrode with finger contact, enabling high-quality ECG recordings and morphology preservation in a practical wearable form factor.
OpenEarable ExG
An open-source hardware extension of the OpenEarable 1.3 platform that enables multifunctional biopotential sensing (EEG, EMG, EOG) in the ear, paving the way for new applications in HCI and wearable health.
HARNode
HARNode is an open-source, time-synchronised wearable system that enables scalable, multi-device human activity recognition (HAR) in real-world environments. Each node combines IMU and pressure sensors in a compact, Wi-Fi-connected module for high-precision motion data collection.
OpenEarable
OpenEarable is an open-source, AI-enabled platform for ear-based sensing applications with true wireless audio. The modular and reconfigurable platform is packed with a variety of high-precision sensors, designed for both development and research applications.
EarXplore
EarXplore is an evolving, interactive database that organizes and visualizes research on earables. It helps the community explore existing studies, uncover trends, and shape the future of earable technology.
Theses
No open theses.
