Recent advance in genomics are generating tremendous amounts of data. As a result, the field of bioinformatics confronts an unprecedented need to move towards greater interdisciplinary to better interpret and understand these data. The goal of our research is to understand the molecular underpinnings of various plant adaptations to semi-arid and arid environments through genomics-enabled bioinformatics approaches. Our research focuses broadly on comparative genomics and gene expression from the perspectives of genomics, systems biology, and bioinformatics. We propose to undertake integrative approaches that span multiple levels of biological organization from the genome to the metabolome.
