Background and activities

My background is in the area of Human Computer Interaction and Collaborative/cooperative learning. In particular my doctoral work was in the area of using eye-tracking data to explain the differences between, and predict, experts and novice groups; good and poor students; functional and non-functional groups. The main context for the application of my research has been education. My research interests are primarily in the area of Applied Machine Learning and Human-Computer Interaction (HCI) with heavy emphases on groups’ behavior and physiological data such as eye-tracking, EEG, facial expressions (theoretical and practical methods in digital interaction). I seek to understand relations between users’ data (eye-tracking, system log data, users’ actions) and the profile of the user (expertise, motivation, strategy, performance) based on empirical experimentation (controlled experiments) and mixed methods analysis (utilizing a multitude of digital technologies). The knowledge gained from these studies is then used to provide feedback to the group or adapt for the needs of the group in a proactive manner. For this effort, in my studies I have combined eye-tracking and users’ actions to provide more comprehensive results through data science, statistics and machine learning practices. 

After finishing my doctoral studies in 2015, I started working on developing methods based on Extreme Values Theory (EVT), a methodological space to compute features from abnormalities in data emerging out of collaborative work. EVT is well suited for big data time series. The results show an improvement over contemporary feature extraction methods in terms of their prediction capabilities. During the same period, I have expanded my application area beyond collaborative and educational technologies and have conducted studies in the context of ecommerce, information systems and Entertainment Computing.
