Experience and Current Work
Meital’s research centers on the biopsychosocial mechanisms by which stress impacts mental and physical health over the lifespan. She is particularly interested in studying adversity during sensitive life periods (prenatal, childhood, adolescence) and their effects on multiple physiological processes (e.g., neuroendocrine, immune, epigenetic, cellular aging) and various health outcomes (e.g., depression, obesity, cardiometabolic dysfunctions). Meital aims to scrutinize individual differences in these pathways and to identify protective factors which may buffer individuals from the adverse effects of stress on health. She seeks to understand these questions to inform targeted prevention and intervention programs aimed at improving the health and well-being of at-risk individuals.
During her doctorate studies, Meital have examined the co-development of inflammation, adiposity and depression across adolescence, with a focus on sex differences, developmental trajectories and bidirectionality. Additionally, since the COVID-19 pandemic began, Meital and her colleagues have been investigating parents’ behavioral and emotional responses to the pandemic, their caregiving, and the effects on child adjustment.
As a TRIM postdoctoral fellow, Meital continues to pursue her research interests in developmental psychobiology, and by collaborating with UCSF faculty she is investigating the effects of early life adversity on biomarkers of health and aging. She is also researching Intergenerational transmission of stress by examining the effects of maternal childhood adversity and pregnancy stress on child’s epigenetics, health and socioemotional development. Additionally, she is collaborating with Osher Center faculty on Mindfulness intervention studies aimed at improving health and stress responses of vulnerable populations (e.g., women who have experienced adversity, pregnant women).
