Research Topic: The use of machine learning in the search for di-photons in association with missing transverse energy. LHC data is generally characterised by high dimensionality and class imbalances therefore sophisticated models are often required to analyse it. We consider fully supervised and weakly supervised learning paradigms. We employ ML and DL techniques to discriminate between background and signal events. Background events are well researched so we are not particularly concerned about misclassifying them, however, we pay special attention to how the model classifies and misclassifies signal events as they are extremely rare. The research forms part of a larger study to investigate physics BSM, particularly the Madala Hypothesis.

BSc(Hons) Comp. & Applied Mathematics

2017 - 2017

University of the Witwatersrand, Johannesburg

Research Topic: Modelling a slinky falling inside a viscous fluid. When a slinky is dropped in the air, it exhibits a strange behaviour where it's bottom part "temporarily defies gravity" by remaining suspended in the air until its top part hits it. We investigate the mechanics of this behaviour, mathematically derive the governing equation and find the general solution for it.
