The Cosmic Gravitational Wave Background (CGB) is a hypothesized relic radiation field that, if detected, would give us clues to the earliest moments of the history of the Universe. In this talk, accessible to students and non-experts, I will describe the physical processes that can give rise to a CGB, novel features including a net polarization of the gravitational waves (as distinct from the polarization of cosmic microwave background photons), and methods of detection.

Our group is investigating the mechanics of a key structural protein, collagen, which is comprised of three chains that coil to make a triple helix. Collagen is the fundamental structural protein in vertebrates and is widely used as biomaterial, for example as a substrate for tissue engineering. In spite of its prevalence and mechanical importance in biology, the mechanics of collagen is surprisingly unresolved.

The LSND and MiniBooNE short-baseline neutrino experiments have provided evidence for neutrino oscillations at a mass scale of approximately 1 eV. When combined with oscillation measurements at the solar and atmospheric mass scales, these experiments imply the existence of more than three neutrino mass states and, therefore, one or more "sterile" neutrinos. Such sterile neutrinos, if proven to exist, would have a big impact on particle physics, nuclear physics, and astrophysics, and would contribute to the dark matter of the Universe.

Physicists have been exploring techniques for the controlled manipulation of large collections of quantum objects.  A valuable strategy has been placing collections of laser-cooled atoms in optical cavities.  I will review the state of the field, some of the underlying physics, and the outlook.

My research program is motivated by fascination with bird flight. My laboratory group uses a multi- disciplinary approach that includes biomechanics, physiology, and neuroscience to examine flight ability. Our current research is organized around two topics: 1) how birds morph their wings and what benefits this provides; and 2) how optic flow signals are encoded in the avian brain and used to guide their flight. As we gain understanding of flight mechanisms, we further endeavor to apply comparative approaches that provide deeper insight into avian ecology and evolution.
