About the Event "Metamaterials are a design paradigm for the construction of novel composites, where exotic electromagnetic properties arise from geometry rather than chemistry. From negative refractive index to cloaking and perfect lenses to perfect absorbers, metamaterials have demonstrated an extraordinary ability to extend the electromagnetic response of materials. As the underlying physics of these fascinating materials continues to be uncovered, much effort is now shifting toward demonstration of novel applications. I will present the design, fabrication, and demonstration of active metamaterials that function as a real-time tunable, spectrally sensitive spatial masks for use in THz imaging with only a single pixel detector."

Biography I received both my MS and PhD degrees in Physics from UC San Diego, and my thesis work, completed in 2004, was for investigation of the THz, infrared, optical and magneto-optic properties of novel materials utilizing various spectroscopic methods, including Fourier transform spectroscopy and ellipsometry. Materials studied include high temperature superconductors, pyrochlores, and artificial metamaterials. I was an author on the “discovery” paper on “left-handed” or Negative Index (NI) materials, and a main contributor to demonstrating artificial magnetic response at THz frequencies. I was awarded a Director’s Postdoctoral Fellowship from Los Alamos National Laboratory and worked in the laboratory for ultrafast optics in MST-CINT. My postdoctoral work at Los Alamos focused on terahertz time domain spectroscopy of novel materials. I am an Associate Professor of Physics at Boston College - now in my sixth year. In 2007 I was awarded a Young Investigator Program from the Office of Naval Research – a young faculty award – and a Presidential Early Career Award for Scientists and Engineers (PECASE) in 2011. In 2013 I was elected a Kavli Frontiers of Science Fellow. My research interests are primarily directed towards simulating, fabricating and measuring metamaterials at microwave, THz, and infrared frequencies and the characterization of high temperature superconductors. I am an expert in infrared, terahertz time domain, microwave, and magneto-optical spectroscopy.
