Research Overview

Before coming to STOR-i I received a BSc in Mathematics from the University of Lancaster. During my undergraduate degree I looked at a wide variety of topics spreading both pure mathematics and statistics. Even before degree level mathematics I had an interest in statistics, environmental statistics in particular. This lead to me taking a minor course in environmental science in my first year alongside my mathematics degree. During the first year of university I heard about the STOR-i programme and followed its development throughout my degree. It was therefore delighted when I got the offer to take part in the summer internship 2013 to get an insight into research and get to know more about the programme. My project, Background Subtraction: Methods for Video Analysis, focused on surveillance and investigated the effectiveness of different algorithms for background subtraction under a number of real and challenging scenarios. My PhD project focuses on quantification of input uncertainty in simulation with current focus on arrival processes in queueing models. Input uncertainty arises when the inputs to simulation models can only be modelled by a finite amount of data and as such are not certain.
