Dear colleagues,
We invite you to join the Open and reproducible analysis of light exposure and visual experience data online course—a free, live series for researchers analyzing wearable light and visual experience data in R with the open-source LightLogR package.
The series offers two tracks (Beginner and Advanced), each delivered as a two-part course via Zoom. To accommodate global time zones, every session will be offered twice on the same day.
Beginner Track
Tuesday, 7 October 2025
Wednesday, 4 March 2026
Topics: tidy data workflows, preprocessing, metric calculation, visualization, merging auxiliary data, and photoperiod analysis
Tuesday, 9 December 2025
Wednesday, 6 May 2026
Topics: merging light with sleep and auxiliary streams, advanced visualizations, conditional metrics, time-zone handling, and spectral/distance measures
90-minute live webinars (introduction, demonstration, Q&A)
Offered twice daily: 08:30–10:00 and 18:00–19:30 CET/CEST
Dedicated Q&A with the package developer and maintainer
Certificate of participation (micro-credential) awarded upon completion of both parts in a track
These tutorials are practical, reproducible, and interactive, with ready-to-use code snippets and example datasets. Detailed learning outcomes are provided in the attached PDF.
About the developer / instructor
