Dr. Jesse Berwald from the College of William and Mary will present a seminar talk entitled "Age Classification of Red Blood Cells: Tales From Persistent Topology. Abstract of the talk-- Human red blood cells exhibit vibratory motions, referred to as "flickering". While the dynamics of flickering has not been completely characterized, it may be observed using phase contrast microscopy. In particular, observed coarse topological features seem to suggest a difference in flickering behavior between young and senescent red blood cells. We present an automated topological persistence-based scheme for quantifying aspects of the spatial and spatio-temporal characteristics of this behavior, and demonstrate its usefulness in detecting the age of red blood cells, which has possible implications for blood storage.
