Champika is a lecturer in Computer Science at the Faculty of Electrical Engineering, Mathematics, and Computer Science (EEMCS) and is a member of the Data Management and Biometrics (DMB) group (https://www.utwente.nl/en/eemcs/dmb/people/). Her journey includes a PhD from the Situated Computing and Interaction group of the University Munster, Germany, two Master's degrees ( Master in Electronic and Telecommunication Engineering, and a Master in Information Technology) and a BSc (Honours) degree in Statistics and Computer Science. Before joining the University of Twente, Champika worked as a Content Manager at Innodata (https://innodata.com) and as a Senior Lecturer at the University of Moratuwa in Sri Lanka (https://uom.lk). She has also served in international SIG CHI conference commitees such as MobileHCI (https://mobilehci.acm.org/2020/organizers/) and Mobile & Ubiquitous Multimedia (https://www.mum-conf.org/2020/index.php?web=committee). 

Champika's research interests are Smart Technology, Tangible, Embedded and Embodied HCI, and Situated Computing. Particularly, she is interested in physical-digital systems that enable people to interact with digital systems/information via physical form (physical embodiment of digital). She works towards allowing more natural, multimodal, and situated interaction with computers. Her current work involves using smart technology, sensing and actuation to make data more experienceable and facilitate sensemaking from data. By transforming data into ambient, physical, and multimodal representations (e.g., Data Physicalizations), she aims to rehumanize data and to increase the discoverability, engagement, and overall human-data experience (see: https://www.utwente.nl/en/eemcs/dmb/research/ds/hdi/).
