Research Interests:  Molecular and Developmental Mechanisms of Mendelian Disorders

Our lab studies rare human disease phenotypes in order to gain insight into general principles of human health. Our overall goal is to improve our understanding of the molecular pathogenesis of Mendelian disease by merging clinical observations, genomics and studies in model organisms particularly Drosophila melanogaster. We are currently using Drosophila to study Mendelian disorders and their underlying genetic and develop-mental mechanisms in two major efforts:

1) Model Organisms and the Molecular Pathogenesis of Mendelian Disorders: We use Drosophila models for diagnostic paradigms. We are part of the Model Organisms Screening Center (MOSC) for the Undiagnosed Diseases Network (UDN). Similar efforts are underway related to the Centers for Mendelian Genomics (CMG) and the Simon’s Foundation for Autism Research Initiative (SFARI).

2) Mendelian Disorders of the Peroxisome and Organelle Dynamics: Peroxisomes are fundamental sub-cellular organelles present in all eukar-yotic cells. We use clinical and Drosophila studies in the elucidation of mechanisms of Peroxisomal Biogenesis Disorders- Zellweger Spectrum disor-ders (PBD-ZSD). These diseases are expanding from autosomal recessive disorders to a broad range of human disease related to peroxisomes.
