Research Interests

My work primarily focuses on epigenetics, chromatin structure, and disease, using molecular biology, genetics, biochemistry and animal models. My lab studies the human neurodevelopmental disorder Williams Syndrome, and particularly the role of the chromatin remodeling subunit Williams Syndrome Transcription Factor (WSTF), using the clawed frog Xenopus laevis as a model. In addition, my lab studies the roles of histone modifications in DNA repair and both nuclear and mitochondrial genome stability.
