How a Mother’s Experiences Shape Her Child’s Biology with Dr. Bridget Callaghan
Description
What if the experiences of one generation could shape the biology and emotions of the next?
In this episode of STEMPOWER, I speak with UCLA's, Dr. Bridget Callaghan. Her groundbreaking research explores how early life adversity and maternal experiences influence children’s gut microbiome and socioemotional development.
Together, they unpack Dr. Callaghan’s 2023 study “Multigenerational adversity impacts on human gut microbiome composition and socioemotional functioning in early childhood.”They discuss how early adversity gets “under the skin,” the critical role of the gut-brain axis at age two, and how microbial pathways may help explain the biological transmission of trauma across generations.
Tune in to hear about the mechanisms linking the microbiome to mental health, the challenges of studying multigenerational effects, and Dr. Callaghan’s vision for future interventions that could help break the cycle of adversity.
