Me

Alex Stergiou

I am Assistant Professor at University of Twente's Data Management & Biometrics (DMB) group. My research focus is on video understanding tasks and model interpretability methods. Previously, I was a Postdoc at VUB and a Research Associate at the University of Bristol working with Dima Damen on video understanding. I obtained my PhD from Utrecht University where I was lucky to be supervised by Ronald Poppe and Remco C. Veltkamp. My thesis topic was on human action and interaction recognition in everyday social settings.
