Two short talks: Progress Towards an Efficient Implicit Immersed Boundary Method, and an Extended Version of the Bidomain Model of Cardiac Electrophysiology

Boyce Griffith (New York University)

In the first part of this seminar, I will describe recent progress on developing an efficient implicit version of the immersed boundary method for problems of fluid-structure interaction. In the second part of this talk, I will describe a recent version of the bidomain model of cardiac electrophysiology which accounts for the physiological inhomogeneities in ion channel distributions along the cell membrane. In particular, unlike the standard bidomain model, our "extended" bidomain model allows for different distributions of ion channels along the sides and ends of cardiomyocytes.
