Research Interests

The ultimate goal for my research group is to provide unique insights into neural plasticity and improved brain function after interventions such as cognitive (e.g., motor imagery or memory training) or physical (e.g., cardiovascular exercise) training across the lifespan in both healthy participants and patient groups. My studies usually involve tests of motor and cognitive functions in combination with various brain imaging techniques such as functional and structural MRI and Positron Emission Tomography (PET).
