Research Interests

Imaging technologies adapted to study experimental mice have a unique role in addressing current questions about the relationships between genes and disease.

The sequencing of the human and mouse genomes in combination with the powerful genetic tools now available for the mouse have brought mice to the forefront as a means to understand development and model human disease. These genetic relationships, however, tend to be complex with genes having multiple roles and often complex interactions with other genetic and environmental factors.

As with clinical practice, imaging technologies provide a means to examine in vivo the structure and function of whole organs or the whole mouse. This high level view allows one to find genotypephenotype relationships that are unexpected and allows one to examine questions about the patterning and structure of an organism that would not be apparent in a more focused molecular or cellular analysis.
