Research Overview
The Lappas lab has a number of research themes. Current projects are examining the mechanisms that govern birth (Theme 1) and the development of gestational diabetes (Theme 2). It is hoped that this research will offer new insights into the development of therapeutics for the management of these conditions. Theme 3 is a novel area of reproductive research using dietary phytophenols as therapeutics to prevent adverse pregnancy outcomes. Other projects underway include collaborative studies such as the Mercy Pregnancy and Emotional Wellbeing Study (MPEWS) which promises to significantly advance our understanding the mechanisms through which maternal antenatal emotional disorders impacts fetal outcome.
