  Brighton Analysis of petabyte-scale ATLAS data using feature engineering, cut-based methods and machine learning techniques (such as neural networks and BDTs). Coordinator of the ATLAS collaboration Analysis Software Group. Convener of the ATLAS top quark properties and ATLAS third generation supersymmetry groups (2014-2016). Tutor for the Scientific Computing course, covering numerical algorithms in Python.

Used Bayesian techniques to set first ATLAS limit on the production of top quarks in association with a Z boson. Convened the ATLAS supersymmetry background forum, developing common C++ software used in the ATLAS supersymmetry group and overseeing Monte Carlo and data-driven modelling of background processes. Edited the first ATLAS paper on the top quark charge asymmetry and explored Tikhonov regularisation and Bayesian methods for unfolding. Show less

  Trieste, Italy Developed C++ code to perform the first ATLAS top quark measurement, now cited over 800 times. The code was run on the world-wide GRID to analyze petabytes of complex data, perform feature extraction, data cleaning and transformation into ~100 gigabytes of nested records containing hundreds of variables. Developed the analysis strategy and the background estimation methods, performed optimisation and the statistical interpretation of the measurement.
