My primary research focus is on neurocognitive aging and brain plasticity. This line of work aims to understand why our brains become less adaptable as we age - and to identify mechanisms that can help offset or reverse these changes.
In my earlier work, my colleagues and I published the first studies demonstrating that cardiovascular exercise in older adults (65+ years) can lead to:
• Improved cognitive performance (measured via laboratory-based cognitive tasks)
• Increased brain volume (measured via structural MRI)
• Brain activity patterns resembling those of younger adults (measured via functional MRI)
These findings have since been widely replicated in various contexts, including:
• Normal aging and Mild Cognitive Impairment
• Neurodegenerative diseases
• Psychiatric conditions
• Childhood development
More recently, I have expanded this work to examine how brain and behavioral changes relate to individual differences in metabolic and physiological markers across the lifespan. One of the more exciting current approaches focuses on understanding how rapid, moment-by-moment physiological changes correspond to momentary changes in behavioral adaptation. To address this, we have developed novel methods and approaches that enable:
• Simultaneous measurement of physiology and behavior at high sampling rates (30+ times per second)
• Analysis of dynamic relationships between brain function, behavior, and immediate physiological fluctuations
Preliminary results from these studies suggest a complex and dynamic relationship between these systems, offering new insights into how the brain adapts (or fails to adapt) to changing cognitive demands.
