Biography

Richard Buxton is a physicist specializing in functional magnetic resonance imaging (fMRI). His primary research focuses on understanding the connections between neural activity, blood flow, and energy metabolism in the human brain. He employs arterial spin labeling (ASL) and blood oxygenation level dependent (BOLD) methods to estimate changes in brain oxygen metabolism in response to various stimuli and drugs. His theoretical work encompasses mathematical modeling of imaging methods, the BOLD effect, and the transport of oxygen in blood and tissue. Beyond brain research, Dr. Buxton collaborates with pulmonary researchers at the Pulmonary Imaging Lab, investigating the application of ASL methods to measure dynamic blood flow changes in the lungs. He is based at the Center for Functional MRI and served as its founding director from 2000 to 2007. Dr. Buxton authored a textbook on fMRI, the second edition of which was published by Cambridge University Press in 2009. His projects include 'Defining Neurovascular Coupling Variability Using Quantitative Functional MRI' and 'Dynamics of Oxygen Metabolism in the Human Brain.'
