Research Interests


Characterization of mutant phenotypes and the molecular basis of embryonic and neonatal development, as well as the study of models of heart disease and muscular disorders; utilizing gross pathology, routine histology, in-situ hybridization, and immunohistochemistry techniques. Clinical and research expertise in gross pathology/necropsy, histopathology, specialized microscopy, digital and 35mm imaging and analysis, desktop publishing and graphics.
