Research Interests

As a neuroscientist and psychologist, I study the mechanisms of decline, maintenance, and plasticity of cognition, brain structure, and function during the adult lifespan. I focus on assessing the effects of lifestyle interventions (randomized longitudinal control trials with exercise, dance, nutrition) on brain integrity, cognition, and everyday performance. I employ multiple magnetic resonance (MR) neuroimaging techniques to measure white matter (WM) integrity (diffusion tensor (DTI), T2 imaging, and MR elastography), brain volume (surface- and voxel-based morphometry), as well as spontaneous and invoked brain activity (resting state and task-related functional MRI) along with behavioral measurement of cognitive processes.

In my research I aim to integrate multiple MRI modalities to best characterize structure- function relations in the healthy aging and adult brain. I am specifically interested in multimodal and longitudinal assessment of the aging white matter.

My main focus is on the relationships between physical fitness, physical activity and the brain and cognitive health. I am interested in studying both typical low fit and low active aging populations, as well as exceptionally fit and well functioning older adults; for example, we studied the brain of Olga Kotelko, nonagenarian athlete: http://well.blogs.nytimes.com/2015/09/02/physed-4/?_r=0. With my collaborators we are one of the first to use objective measures of physical activity in combination with neuroimaging. A related area of my research focuses on the effects of long-term training on the brain, such as in professional dancers (see current projects).

Current and Recent Research Projects

In the BRAiN lab we are currently working on data analysis from two main projects: FAST and MODERN.

FAST: fit and active older adults (Influence of Fitness on Brain and Cognition, NCT01472744 at nia.nig.gov). The study includes >240 participants of age 60–80 who were randomized into 4 intervention groups (walk, walk+nutrition, dance, and active control). MRI, cognitive, physical fitness and activity data was collected pre and post intervention at UIUC (PIs AF Kramer, E McAuley). We are currently exploring the cross-sectional relationships between neuronal markers if brain health, fitness, and cognitive performance, as well as evaluate the effects of interventions on brain health, with the focus on white matter and structure-function interactions.

MODERN: Brain Structure and Function in Professional Dancers. In this study we evaluate the neural correlates and cognitive/motor benefits of professional dancing training in comparison to age- and education-matched controls with no dancing experience. Although dancing has been associated with lowered risk of dementia and higher motor and cognitive functioning in older adults (Granacher et al., 2012; Kattenstroth et al., 2010, 2011), little is know about the effects that intensive dancing exerts on brain structure and function (Haenggi et al., 2009). We collected MRI (structural, task functional and resting state, DTI, elastography), neuropsychological, balance, and video game data at the Lifelong Brain and Cognition Lab at UIUC (AF Kramer). We are currently analyzing the data. The results of this study will help us make predictions on how dancing may enhance brain integrity in advanced age and lie foundation for future study designs an analyses aiming to promote successful aging.
