Treecode methods provide a useful tool for accelerating computation in many-body problems. These methods involve a hierarchical decomposition of the computational domain into a tree-like structure of particle clusters, allowing for fast evaluation of long-range interactions.

In this talk, we explore the application of these tools to two related biomolecular problems. First, we will discuss the evaluation of Coulomb and screened-Coulomb potentials resulting from a collection of point charges. Second, we will explore the application of treecodes to a boundary-integral method for solving the Poisson-Boltzmann Equation, a model for the electrostatic interactions of biomolecules in an ionic solvent.
