Research Interests
Nuclear Magnetic Resonance spectroscopy and relaxation measurements in soft condensed matter systems. Collective motions in model membranes, phase transitions in liquid crystals.

This figure shows the current understanding of what biological membranes look like at the molecular level. Nature tends to utilize the laws of Physics to optimize the design of living things; my ambition is to figure out how the biological organisms, and in particular, membranes, are put together, and then to learn some new Physics from it.

Here are a few selected publications that tell different parts of this story:

Computers and numerical methods in experimental data analysis
I have been involved in the development of some new approaches to dealing with experimental data. Using powerful computers to acquire and analyze experimental data allows one to ask questions that were impossible to answer before, and thus often went ignored - one learned to operate within the realm of the possible. New numerical power at our disposal is changing that; we are ``pushing the envelope'' on what questions an experimental physicist can try to ask of Nature.
