Research Interests: Use of genomic and bioinformatics tools to identify genetic causes of human disease. I am a medical geneticist, and my research bridges clinical genetics and basic science. Our work is focused on using new genomic technology and bioinformatics tools to identify mutations that cause intellectual disability and other neurodevelopmental disorders, and in applying what we learn to improve the clinical care of affected individuals and their families.
