Abstract

Big Data in biomedicine and healthcare presents a significant research challenge. The amount of unstructured and semi-structured data that are generated by advances in medical imaging and other health data (sensors, records etc) are already exceeding the limits of conventional approach to data analysis and visualisation. For example, advances in biomedical imaging are resulting in unprecedented amount of information of the human body structure, function, and pathology. In particular, positron emission tomography (PET) imaging is capable of representation, characterisation, and quantification of biological processes at cellular and sub-cellular levels within living organisms. Coupled with the anatomical information from the computed tomography (CT), combined PET-CT introduces superior capacity to accurately localise and quantify a variety of physiological and biological events at a tissue or cellular level. These improvements in imaging capabilities are constantly challenging research to maximise the extraction of meaningful information, while not overloading the user, embedded within not only just one single set of images, but also from a large amount relevant images (population) and other sources (derived knowledgebase of disease patterns) to improve the understanding and to present the knowledge in an intuitive way.

My research aims to offer a solution to this challenge by devising a new ways to view and interact with these large multi-modality datasets with 3D visualisation and analysis. This includes fundamental computer science research, including knowledge-based decision support system (computer-aided image diagnosis), scalable database searching (graph-based image matching), and optimisation (multi-modal image visualisation). This talk will present some of our recent achievements in three projects – Disease map, Medical Avatar and Visual Telehealth. Further, a unique multi-disciplinary Telehealth research partnership between the Nepean Hospital and the institute of Biomedical Engineering and Technology (BMET) will be introduced.

Speaker's biography

Dr Jinman Kim is a Senior Lecturer at the School of IT and the Director of the Telehealth Technology Centre, providing research coordination and leadership for a large Government funded project allocated to the Nepean Hospital. This fund will establish Telehealth best practices, including research and development, to support its surrounding rural and regional areas. Dr. Kim received his PhD in CS in 2005 and worked as an ARC Postdoctoral Research Fellow, during which he took a no-pay leave and worked as a Marie Curie Experienced Researcher in an internationally well-known MIRALab (in 2009-10) for a European joint research project. He assisted in coordinating 8 partners from 6 countries including EPFL, INRIA and UCL, as well as coordinating in the writing of EU proposals. He has also played a key role in our Faculty’s newly established Institute of Biomedical Engineering and Technology (BMET).

He is a Guest Editor of the Special Issue on Telehealth Technology for the IEEE Journal of Biomedical & Health Informatics (former IEEE Transaction of Information Technology in Biomedicine). He is a reviewer of the ARC and for several leading publishers in his field, including IEEE Transactions, Springer Journal of Visual computing, Elsevier Computer Methods and Programs in Biomedicine, and many international conferences. He has been involved in organizing a number of conferences, including IEEE PacificVis (as Publicity Chair), the International Federation of Automatic Control (IFAC) Symposium and the 3DAH workshop held in Greece. He has been on the international programme committee of the CGI since 2011 and will bring the next CGI to Sydney in 2014 as the Technical Committee Chair.
