Pregnancy is a complex and complicated process involving thousands of genes that are ‘turned on’ and ‘turned off’ in precise and specific sequences. How a sequence of events and the expression of the genes is timed is still largely unknown—however, the impacts of mistiming can be devastating. Our research into transcriptomics focuses on learning how signals and expression during normal and not-so-normal pregnancies compare and how those differences can signal to a care provider before clinical signs are present.
