Physics 2, 36 (2009) – Published May 4, 2009 Statistical Mechanics Biological Physics Faster does not mean more precise—a new view of how proteins diffuse and bind to a specific site on the DNA reassesses the role noise plays in the biochemical production line that creates biomolecules from genes. |

Physics 1, 8 (2008) – Published July 28, 2008 Statistical Mechanics Biological Physics Current technology permits tracking single molecules with exquisite precision, but the results need to be interpreted with care. Long-duration measurement of the motion of a single particle yields information that is different and complementary to that obtained from an ensemble average of many particles. |

Published July 21, 2008 Biological Physics Statistical Mechanics Molecular dynamics simulations show that thermal gradients – of order 1010 K over a meter - can polarize liquid water. The finding could have interesting implications for developing hyperthermal treatments that target cancer cells. |
