I'm currently studying the physics of artificial biomembranes, biopolymers such as DNA, and other "soft" condensed matter systems. There is a great cultural gap between physics, which seeks to understand extremely simple systems, and biology, which is obliged to study the overall behavior of extremely complex systems. I think that one area where simplicity and life intersect is the study of biomembranes and biopolymers, both in isolation and as active elements of cells. Membranes and polymers display the sort of universal behavior amenable to the powerful tools of statistical physics, thus making these systems are a bit more inevitable, less accidental, than more complex architectural elements of life. Nature has made extensive use of these generic properties in constructing useful materials and molecular machines; moreover, artificial analogs of biomaterials are subjects of intense investigation for a wide variety of bioengineering applications. Of course, physicists have been studying membranes and polymers for much of this century. Much physical research on these systems has concerned bulk systems, in thermal equilibrium. But the activities of many molecular actors are obscured when we look at them in bulk; new, single-molecule techniques reveal much that was previously hidden. Also, life processes take place far from equilibrium. So we have been studying mainly experiments involving the manipulation of single molecules of DNA, and dynamical phenomena involving membranes. I have some interest as well in general nonlinear dynamics (including pattern formation), self-assembly, electrostatics at the colloidal level, and the general area of geometrical methods in physics.
