Research Interest

Dr. Wiles approaches comparative biology utilizing both “classical” and computational genomics and proteomics, specifically protein-protein interaction (PPI) networks (interactomes). The union of comparative genomics and bioinformatics provide powerful and informative tools to the research scientist: some model organisms are better suited to a particular line of research or experiment type, and applying knowledge across species can fill in knowledge gaps while allowing for focused experiments. This has a tremendous impact on basic science research applications in that what scientists study at the bench can be translated to directly improve human health.

Dr. Wiles’ primary research goal is to understand how cells respond to nutrient stimuli by elucidating novel pathways involved in nutrient response and characterizes functional analogs and new genes related to nutrient biology. From growth and development, to the end of the life of a cell, response to its environment is critical. Upon aberrant response to a stimulus, the operations of the cell may go awry, resulting in the development of disease. Misregulated sulfur metabolism, for instance, has a direct effect on liver function, while defects in nitrogen metabolism may affect amino acid synthesis and turnover. Dr. Wiles uses the yeast Saccharomyces cerevisiae in molecular biology investigations, while conducting comparative genomics and proteomics in silico across multiple species. There are opportunities for students, both at the bench and at the computer, to be involved in active research in her lab.
