The primary aim of my research program is to elucidate the neurocognitive mechanisms involved in adapting to and controlling the influence of emotional events on the brain and behavior across the lifespan, and to determine how these mechanisms can be manipulated so as to promote mental wellbeing in both healthy individuals and those with mental illness. To this end, my lab is currently pursuing the following interests and related questions:
The neurocognitive mechanisms involved in controlling and adapting to emotions
- How does varying cognitive demands change or modulate the representation of emotional features; and conversely how do emotionally salient objects alter cognitive processes like awareness, working memory and attention in early sensory cortices?
- How do phylogenetically older processes such as associative learning and extinction interact with higher-level cognitive processes?
Affective disorders, including depression, bipolar, and anxiety, and their development
- Can we determine how early perceptual processes are influenced by, or are influencing, the maladaptive behavior observed in disorders of emotion?
- How do various treatment options, including pharmacological and alternatives like C.B.T., physical activity or meditation, affect the neurocognitive mechanisms of emotion regulation?
Application of cutting-edge neurocognitive/neuroimaging methods and analyses
- Functional MRI (BOLD), diffusion tensor imaging (DTI)
Multi-voxel pattern analysis; functional connectivity
