Personal profile

I am a lecturer in Computer Science at the Faculty of Electrical Engineering, Mathematics, and Computer Science (EEMCS). My current teaching involves Data Physicalization, Human-Computer Interaction, Smart Technology, and Research and Design for User Experience. 

I received a PhD  from the University of Munster in Germany. My PhD thesis focused on overlapping ares of Mobile & Ubiquitous Computing,  Information Visualization and Human Computer Interaction. I completed my Master's degree in Electronic and Telecommunication Engineering from the University of Moratuwa in Sri Lanka. I also obtained a second Master's degree from the School of Computing, University of Colombo, and a BSc (Honours) degree in Statistics and Computer Science from the University of Kelaniya in Sri Lanka. Prior to joining the University of Twente, I worked as a Content Manager at Innodata ( and as a Senior Lecturer at the University of Moratuwa in Sri Lanka ( I completed the University Teaching Qualification (UTQ) and have obtained SEDA (UK) accreditation for teaching, learning, and assessing in higher education.

I am interested in T-shaped research that combines the strengths of multiple disciplines to design solutions that empower humans and the environment. My current research focuses on the overlapping areas of three fields of computer science: Smart Technology/ Physical Computing, Data Science, and Human-Computer Interaction. I do research that focuses on combining the strengths of these three fields to add tangibility and physicality to computing and to materialize the de-materialized world in a healthier and impactful way. My research along this this line spans along two main directions: Data  Physicalization and Tangible Interaction.

My current research in Data physicalization focuses on physical and mutisensorial visualization of data. I explore various physical means for representing data to provide more graspable and impactful human data experiences. My current research in Data Physicalization aims at (i) Exploring sensing and actuation as material for representing data, (ii) Making data representations everyday objects (moving away from traditional screen-based visualizations, let's embed data to our real-life spaces), (iii) Exploring human skill-based interaction methods (let's say goodbye to the mouse), and (iv) Exploring smart-object based realtime modelling and processing of data to enable smart data objects (smart data objects that sense, process, learn and adapt their behavior themselves!)
