Not too long ago, a description of my research group's work on singular optics with polychromatic light was published (unbeknownst to us) in a Russian science magazine. A pdf version of the article can be viewed here. For an English description of this research, see paper 22. To see an article about the experimental confirmation of this research, click here.

Some of my work on partially coherent beams propagating through turbulence has been verified experimentally. To see an article about this, click here.

Work I did with Professors Wolf and Agarwal on the coherence properties of sunlight was described in the scientific press at Physics News Update and Astronomy. I have pdf versions of the pages here and here.

Work I did with my collaborators in Amsterdam on plasmons and Young's interference experiment was described in Physics World (though I am not mentioned by name). See the article here.

In recent months the idea of dielectric invisibility devices has become quite popular with the media. Thanks to my thesis work on 'invisible objects,' I was asked to comment on these recent results. Comments appeared in Science Magazine, PhysOrg.com, The News & Observer, and even USA Today.

My proceedings paper for my invited talk at Photonics West 2007 is here.
