## 1. What are the main scientific questions about light, and have we chosen them well?

This is our current research agenda. Are these really the most important questions? What is missing, and what can you contribute? Propose a question, explain its significance and identify a first way to investigate it.

## 2. How does the body perceive and respond to light?

Distinguish vision, non-visual responses, absorption in skin and other tissues, photochemistry, heat and signals between organs. Identify the target, dose, mechanism, response and limits of evidence.

## 3. How should light, darkness and twilight alternate in human life?

Consider the whole day, biological phase, prior exposure, dawn, dusk and uninterrupted night-time rest. Evaluate sleep, performance, recovery and comfort separately.
