Optoneuroepigenetics lab

Variations in maternal care profoundly influence multiple aspects of offspring development. These maternal effects are observed across a wide range of species yet we have a limited understanding of the neurobiological basis of maternal care and its effects on offspring neurodevelopment. 
The lab uses optogenetic manipulations paired with next generation sequencing to characterize the critical brain circuits and transcriptional pathways required for the induction and maintenance of maternal behavior.
The lab is also affiliated with the Ludmer Centre for Neuroinformatics and Mental Health. The Centre provides an internationally unique research platform integrating neuroscience, computational biology, mathematics/statistics, genetics, epigenetics, bioinformatics, and epidemiology, together with advanced computing capacity and IT technology.
