Rat Thermoregulatory Modeling

We aim to develop mathematical models that link heat exposure to organ damage in a rat animal model. To this end, we are developing physiological models based on the three-dimensional anatomy of a rat, in order to quantitatively describe the spatial-temporal temperature distribution across the animal's organs in response to exertional and environmental heat stressors. By integrating this information with the associated dynamic changes in gene products, we aim to develop molecular models that correlate with organ damage.
