Dr. Shalev’s research entails an interdisciplinary approach to identify mechanisms underpinning the biological embedding of stress across the lifespan. His research combines the disciplines of molecular genetics, endocrinology, neurobiology and psychology. Specifically, his research tests the effects of stress from early life on change in telomere length and other biomarkers of aging across the life course, and the consequences of change in telomere length for physical and mental health problems. Dr. Shalev’s current work explores temporal differences in gene expression and epigenetic changes in response to environmental stressors in the lab, as moderated by early life stress.
