Welcome to my webpage in The Department of Physics and Astronomy at The Johns Hopkins University. The current main interest of my group at Hopkins is exotic electronic states of matter at low temperatures, including novel superconductors, exotic magnetic states, electronic glasses, topological insulators, strong spin-orbit coupling, and materials in proximity to quantum critical points. Other areas of interest are nanostructures, biological physics, and various aspects of physical chemistry and quantum optics.
have developed a number of low-energy optical spectroscopies in
the so-called 'Terahertz gap' - the experimentally difficult frequency
region above that attainable with electronics, but below that
accessible with optics (photonics). This frequency range (and attendant
picosecond time scales) is host to many phenomena in condensed matter
systems and is a true frontier in 'optical' and condensed matter
research. Among other experimental apparatuses, we are
implementing a novel time-domain THz spectrometer, which is one of the
emerging tools for condensed matter physicists in obtaining
spectroscopic information in this technically challenging frequency
range. A new microwave `Corbino' broadband spectrometer has also
The investigation of the above materials systems with THz and broadband microwave radiation are wide open areas with great scientific and personal opportunity. Interested students (graduate and undergraduate) should please come by to talk. But I encourage you to first look through some of my recent papers or some lecture notes that I wrote for the purpose of giving interested students some background in technical topics of interest to me.

If you would like to apply to graduate school at Johns Hopkins and are interested in my research, please feel free to get in contact. However, note that I am not on the admissions committee and make no decisions about admissions. Please apply to graduate school @ JHU through the standard channels on the department's website.

"...Sisyphus teaches the higher fidelity that negates the gods and raises rocks. He too concludes that all is well. This universe henceforth without a master seems to him neither sterile nor futile. Each atom of that stone, each mineral flake of that night-filled mountain, in itself forms a world. The struggle itself towards the heights is enough to fill a man's heart. One must imagine Sisyphus happy." - Albert Camus, Le Mythe de Sisyphe, 1942
