We rely heavily on cutting-edge technologies such as microarrays, DNA sequencing, quantitative RT-PCR, and bioinformatics to generate biologically-meaningful data. The integration of these data sets is at the core of our Systems Biology efforts in Nutritional Sciences. We use large animals as primary models but also perform more fundamental studies with animal tissue cell lines or explant cultures. Through the use of high-throughput techniques and bioinformatics we intend to identify genes that might be associated with susceptibility to immune and metabolic diseases (e.g. hepatic steatosis, mastitis) and also to developing obesity.
