Area of Interest

1) Fetal preparation of the lung for birth I am interested in the transcriptional programs that take place in the lung during the last third of fetal development and prepare these organs for normal postnatal function. Using genomic technologies, previously microarrays and currently RNA sequencing I am studying gene expression changes in the rodent lung during this period. My aim is to identify novel molecular mechanisms that can provide us with novel tools for intervention. Particular focus is placed on non-coding RNAs (microRNAs and long noncoding RNAs) that have not been previously annotated or appreciated as gene regulatory elements of the genome.
2) The molecular biology of necrotizing enterocolitis I am studying the interaction between intestinal bacteria and host factors, in particular the intestinal pattern recognition receptors (PRRs). We have described the developmental regulation and role of a novel PRR, NALP-6 in the intestine. In collaboration I am also studying the effects of probiotics on the preterm intestinal microbiome.
