Title: Sharp resonances and large covers of hyperbolic surfaces
Abstract: (joint With D. Jakobson and L. Suares) In this talk we will look at the spectral properties of infinite area hyperbolic surfaces in families of covers. Depending on the structure of the covering groups we establish several asymptotic results on the distribution of resonances in the large degree limit.

Low regularity conformally compact Einstein metrics.

A C^2 conformally compact Einstein metric has sectional curvature decay to -1 up to corrections that are quadratic in the boundary defining function. In this talk I'll discuss the relationship between the curvature decay rate of a generic asymptotically hyperbolic metric and the regularity of the conformal compactification. I then discuss recent work with John M Lee that proves the existence of a low regularity conformally compact Einstein metric with quadratic curvature decay.

Title: 
Extreme Value Theory

Abstract:
Extreme Value Theory (EVT) is a discipline in statistics used to model low probability high impact events. It is often used to estimate extremes in hydrology, the environment, and financial data. In this talk, I’ll give a short description of two methods in EVT (the Block Maxima model and the Peaks-Over-Threshold model) and a few applications of what they can be used for.
