Dr. Dunn-Rankin studies combustion, sprays and particles using optical diagnostics and laser spectroscopy.
Generally, he is interested in the fundamental information that can be obtained from simplified systems which mimic a specific behavior in more complex systems. Using non-intrusive laser diagnostics, he probes the simplified systems in order to develop physical insight into influencing factors.
His research activities include a study of the electrical aspects of microgravity combustion; an effort to develop techniques to measure the size of airborne droplets and particles using laser holography; and experiments associated with gas hydrates and deep ocean power science.
