Prion proteins cause a variety of fatal neurodegenerative diseases in mammals but are harmless to yeast, making it an ideal model organism for these diseases. My research focuses on stochastic and deterministic models of both prion protein dynamics within individual yeast cells as well as how those yeast cells grow and divide to create a heterogeneous colony of cells. Determining kinetic parameters of prion replication in yeast are complicated because experiments reflect both the disease and yeast population dynamics.

Persistence probabilities concern how likely it is that a stochastic
process has a long excursion above fixed level and of what are the
relevant scenarios for this behavior. Power law decay is expected
in many cases of physical significance and the issue is to determine
its power exponent parameter. I will describe recent progress in this
direction (jointly with Sumit Mukherjee), dealing with stationary
Gaussian processes that arise from random algebraic polynomials
of independent coefficients, as well as recent progress
