Gene-diet interactions, obesity, diabetes, and systems genetics
The Parks Lab is focused on addressing the question of how genetics and diet interact together to contribute to common metabolic diseases, such as obesity and diabetes. Through the use of large-scale integrative genetic studies in the mouse we have identified several candidate genes that mediate gene-diet interactions. Current work is focused on a novel candidate drug target, Agpat5, which improves common symptoms of obesity and diabetes. In addition to this work we have a strong interest in the development of systems genetics approaches for dissecting biological pathways and networks.
