🌙 Open-source sleep diary app for clinical research — built with React Native & Expo. Morning & evening questionnaires, sleep metrics, data export (CSV/JSON), and push notifications.

⌚️ A fully reproducible R/Quarto analysis pipeline validating the ActTrust® actigraphy device for energy expenditure estimation and physical activity intensity classification in young adults, benchmarked against the ActiGraph® GT3X+ and indirect calorimetry.

😴 A curated collection of validated sleep questionnaires in Markdown format, intended for research and clinical reference. Each file contains the full instrument, response options, scoring instructions, interpretation thresholds, the original publication reference, and notes on validated translations.

🚴 R analysis pipeline for the study of recurrence-matrix entropy during cycling and rest, using scalp EEG recorded from healthy adults in four behavioural conditions.

⚛️ Julia implementation of recurrence-matrix entropy for quantifying the complexity of physiological time series.

⏰ Data-driven framework for identifying and characterizing circadian phenotypes in visually impaired human participants using non-parametric actigraphy metrics. The pipeline integrates dimensionality reduction, clustering, SHAP-based interpretation, and statistical analyses to investigate circadian rhythmicity beyond pupillary light reactivity.
