Description of Research Expertise
My research lab is focused on elucidating the molecular etiologies of syndromic and non-syndromic human developmental disorders and birth defects. Towards this end we have major projects focused on: 1) understanding the genome-wide implications of alterations in the cohesin complex and its regulation in causing the phenotypic differences seen in Cornelia de Lange Syndrome (CdLS), 2) Characterizing the effects on genome-wide expression in the Pallister-Killian Syndrome (PKS) and defining a minimal critical region on chromosome 12p, 3) Identification of novel genes for non-syndromic sensorineural hearing loss through standard positional cloning, genome-wide copy number variation (CNV) analysis and association studies and 4) Identifying conserved non-coding element disruptions as a cause of isolated non-syndromic congenital heart defects.Description of Clinical Expertise
As a pediatrician and clinical geneticist, my clinical interests are mainly focused on dysmorphology and pediatric genetic disorders. While I see children with any findings suggestive of an underlying genetic etiology, I also have multispecialty clinics for children with several of the diagnoses that we have targeted research interest in such as Alagille syndrome, Cornelia de Lange syndrome, Pallister Killian syndrome and related diagnoses. I also run a dedicated genetic clinic for children with sensorineural hearing loss.Selected Publications
