I study how people find, evaluate, and consume information online, and how Information Retrieval systems (e.g. search engines) can be augmented to foster human-learning and knowledge-acquisition. This interdisciplinary research direction is known as Searching as Learning (SAL), and spans Human-Computer Interaction (HCI), Interactive Information Retrieval (IIR), and Neuro-Information Science, among others.
I use eye-tracking, EEG, and GSR (which fall under the umbrella of Neuro-Physiological methods) to observe people’s behaviour as they interact with online information. These bio-signals help us to understand, model, and predict various aspects of human information-behaviour, such as relevance-judgement, knowledge-gain, and mental workload. My broader vision is to use these bio-signals as real-time, implicit-feedback mechanisms for next-generation interactive computing systems.
