## Modeling Objectives

- Develop a mechanistics ODE model of the population to predict gene expression dynamics
- Question? .... Will the color production be fast enough to be useful to the user? Or will it be too late?
- What is the relationship between UV exposure and reporter gene expression?
- Can we construct a useful calibration curve of color as a function of UV?
