Description of Research Expertise
2b9 In BarziLab, we are interested in what drives variability in the development of brain and behavior in children and adolescents who develop under stress. We are especially interested in understanding mechanisms of risk and resilience leading to youth suicidal behavior. Using large datasets of youth who have been genotyped and deeply phenotyped, we study how a myriad of environmental exposures (such as trauma and poverty) dynamically interact amongst themselves (i.e., within the exposome), as well as with biological factors (genetic, epigenetic, immune) to drive suicidal behavior. We are committed to conduct impactful translational science that will help reduce teen suicide.e 29
