Hi, I’m Emma Kroell.

I was delighted to be awarded the Department of Statistical Science’s Student Leadership Award. This award recognizes my contributions to the department, including my work as President of the Statistics Graduate Student Union and my work organizing this year’s Student Research Day conference.

We propose a reverse stress testing framework for dynamic loss models (in particular, compound Poisson processes over a finite time horizon). We define the stressed model as the probability measure under which the process satisfies the constraints and which minimizes the Kullback-Leibler divergence to the reference compound Poisson model. We solve for the stressed model and illustrate the dynamic stress testing by considering stresses on risk measure constraints such as Value at Risk. Read more
