My work is focused on Computer Vision and Machine Learning
I am a 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. dr. Remco C. Veltkamp.
During my time at Utrecht I have also worked on improvements on the efficiency and explainabilty of spatio-temporal deep learning models and methods, for scene understanding and classification of videos.
I obtained my Masters in Advance Computer Science from University of Essex working with dr. Adrian Clark. I have also worked shortly at the Institute for Analytics and Data Science (IADS) for a summer project on Neural Networks for structured population data with dr. Spyros Samothrakis.
