Staff profile

Prior to moving to Durham University, Sarah was an Associate Professor at Newcastle University where she was Assistant Co-Director of the EPSRC CDT in Cloud Computing for Big Data and Deputy Degree Programme Director for the MSc in Data Science (with Specialisation in Statistics). She has led work packages on a number of RCUK grants, most notably the £1.5M NERC grant "Flood-PREPARED: Predicting Rainfall Events by Physical Analytics of REaltime Data" and the £358K project funded by the Alan Turing Institute "Streaming data modelling for real-time monitoring and forecasting". Sarah has given invited seminars at research institutions across the world, including Duke, Columbia and Maynooth Universities and the Flatiron Institute in New York. She has a keen interest in probabilistic programming languages and has developed a short-course on the Stan language and software, which she has delivered to a mix of academics and businesses across the UK. Sarah is a Fellow of the Alan Turing Insitute and serves on the editorial board of the new journal ACM Transactions on Probabilistic Machine Learning. She has co-supervised three PhD students to completion, with two more in the final year of their PhD, in addition to five Postdoctoral researchers.
