My present research is centered around the ALS Infrared Beamlines. Together with many collaborators, we perform a wide variety of research using this facility. Topics include Condensed Matter Physics, Cellular Biology, Environmental Science, Bioremediation, Forensic Studies, Chemistry, and Materials Science. My earlier research topics included fullerene materials, high-temperature superconductors, giant magnetoresistance oxides, and spin-Peierls compounds.
I have recently been working to push synchrotron IR spectroscopy beyond its traditional limits. First, I have been developping a new method to combine rapid full-field IR imaging with tomographic reconstruction to yeild full 3D FTIR images in Full Color. Second, my group has been pushing way beyond the diffraction-limit by scattering the synchrotron IR light off an AFM tip resulting in 20 nm resolution with full mid-IR spectral coverage. This revolutionary Synchrotrin Infrared Nano Spectrosopy (SINS) is allowing us to probe materials and biological systems at unprecidented spatial resolution nearly 1000 times better than the state of the art before. We've used it to study Phonon Polaritons in 2D Materials, Plasmons in Single Nanocrystals, and Nanoscale Catalysis.
I have previously worked to develop an exciting new high-power terahertz source using coherent synchrotron radiation. We proposed a new facility employing this revolutionary THz source called CIRCE. Related to developing CIRCE, I am helping to lead a new Terahertz Science and Technology Network.
I am the primary contact person for research at the IR beamlines. If you feel you may have a scientific problem for which the beamlines may be of help, please contact me. In addition to maintaining and upgrading beamline facilities, I am always available to help new users make the most of their infrared reaseach.
I am an author of over 150 research articles (see my List of Publications) and one physics text book, now out in its Second Edition (2009), Solid State Physics: Problems and Solutions by László Mihály and Michael C. Martin. Also see my Citation Profile from Google Scholar.
I enjoy skiing, volleyball, travel, and I am the proud father of twin daughters, Megan and Hannah, born April 1999.
