My work is focused on Computer Vision, Machine Learning and Deep Learning
I am currently a full-time PhD student at Utrecht University's Department of Information and Computing Sciences. My project is based on Machine Learning and Computer Vision for human action and interaction recognition in everyday social settings, supervised by Dr. Ronald Poppe and Prof. Remco Veltkamp. Among others, I am working on improvements for the efficiency and explainabilty of spatio-temporal Deep Learning and Artificial Intelligence methods, in scene understanding and classification of videos.
Before my PhD, I obtained my Masters in Advance Computer Science from University of Essex working with Dr. Adrian Clark. During this time I also worked at the Institute for Analytics and Data Science (IADS) for a summer project on Neural Networks for structured population data with Dr. Spyros Samothrakis. My Bachelor was also at the University of Essex in Computer Science.

These are some of my latest projects from courses and pet projects.
This project presents the use of Bootstrapping (or also known as bagging), to normalise the features of the polling population in order to represent the entire population that is eligible to vote. Additionally, for representing connections between individual features during
bootstrapping, a nearest neighbour method is employed in order for the newly created examples to resemble others from the general population. This technique will be applied to data from the 2016 Referendum that held the question of the remain or exit of the United Kingdom from the European Union.
