P Chris Hammel, Professor of Physics and Director of the Center for Emergent Materials, an NSF funded Materials Research Science and Engineering Center at Ohio State University, uses innovative magnetic resonance techniques to study spin transport and dynamics in quantum fluids, correlated electronic systems, multicomponent magnetic devices and biological materials. A particular focus of his current research is the development of novel, ultrasensitive cantilever-based force detection techniques to extend magnetic imaging studies to the study of scientifically and technologically important spin-based nanostructures. This research is founded on high sensitivity scanned probe magnetic microscopy, particularly Magnetic Resonance Force Microscopy or MRFM. Using scanned probe magnetic resonance microscopy he is studying properties of multi-component systems where electronic spin plays a crucial role or adds functionality; in these structures understanding of buried interfaces or structure is often essential. More broadly, his research interests include Ferromagnetic Resonance Imaging in individual nanomagnets, few electron spin magnetic resonance studies of diamond and silica, imaging spin transport in semiconductors, ESR studies of DNA dynamics, and imaging of superparamagnetic nanoparticles for cell labeling. He is a Fellow of the AAAS and the APS, has presented over 110 invited talks on these topics including ten at the American Physical Society's March meeting, and seven at Gordon Research conferences. He has 120 publications in peer-reviewed journals and has authored six book chapters.
