Equilibrium Statistical Mechanics and Field Theory
Sequence alignment is the most widely used data analysis tool in molecular biology. Detecting and quantifying sequence similarities is an intricate statistical problem, which has profound connections to the statistical physics of systems with quenched disorder. Other projects in this area are concerned with long-range correlations in genomes and with the statistics of RNA secondary structures.
The secondary structure of a random RNA molecule is frozen at low temperatures (a) and molten at higher temperatures (b).
