I am an epidemiologist with background in computer science and PhD in neuroscience. The goal of my work is to understand links between environmental exposures and brain development. Most of my current research is about environmental factors of autism spectrum disorder (ASD), with a special focus on air pollution. ASD is a serious developmental disorder with increasing public health implications. In recent years it became clear that ASD is more prevalent than previously believed, and that both genetics and environmental agents are implicated in autism etiology. However, the identity of these agents, the magnitude of their effects, their mechanisms of action and their interaction with susceptibility genes is yet to be revealed. Such discoveries may prevent some of the future autism cases through reduced exposure, by focused environmental regulations and different behaviors during critical exposure periods. I also study environmental factors of neonatal thyroid hormones and the role of these hormones in brain development and ASD.
