2014 – 2017
Sajjad'd PhD was supervised by Ashish and Fiona, and he focussed on a very interesting problem - whether errors in GCM simulations can propagate and create biases in derived attributes (such as flows). He used Second Order Analysis (representing the second order terms in a Taylor Series expansion of a differential equation) and showed these biases can be significant.
His papers (some in review still) were:
