Biography
I am working on developing statistical methods for detecting bifurcations and transitions in climatic time series. Pilot results were published in a GRL paper (2007), and now I am working on the extended method, involving estimation of the noise level and potential shape of the system from its time series.
In 2008, I received a NERC grant as a researcher co-investigator in the project “Detecting and classifying bifurcations in the climate system”. In October 2009, I was awarded AXA Postdoctoral Fellowship.
My recent CV is available here.
