Charlie is a PhD Student in Computer Science at the University of Warwick and is supervised by Professor Graham Cormode. Prior to this he completed his MSci in Mathematics from the University of Birmingham in 2016.
Large datasets are ubiquitous in modern society but a common problem is how to deal with such massive datasets? Charlie’s research is concerned with reducing large datasets into smaller, manageable summaries which can be used to approximate key properties of the data. He is also interested in the related questions of whether these approximations can be performed in a reasonable amount of time and whether they can be used in different models of computation; for example, when data arrives one item at a time and only a small amount of it can be kept. These issues span both theoretical and practical backgrounds and will be of interest to anyone who performs large-scale data analysis.
