I am a PhD student in the Information eXperience lab (IX Lab) at The University of Texas at Austin. I am supervised by Dr. Jacek Gwizdka.

I study how people find, evaluate, and consume information online; and how we can improve this overall information experience. 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.

My research interests span Human-Computer Interaction (HCI), Interactive Information Retrieval (IIR), and Neuro-Information Science.

Google Scholar has the most up-to-date list of my publications. You can also find them in my CV.
