About me

I am a doctoral student and system developer in Health Informatics Center (HIC). I am interested in technology driven research approaches and its applications to e-health, medicine and clinical research.

Granted projects:


  • TERMINET (nexT gEneRation sMart INterconnectEd ioT)

The vision of TERMINET is to provide a novel next generation reference architecture based on cutting-edge technologies such as SDN, multiple-access edge computing, and virtualisation for next generation IoT, while introducing new, intelligent IoT devices for low-latency, market-oriented use cases. TERMINET’s primary intention is to bring (more efficient and accurate) decisions to the point of interest to better serve the final user targeting at applying distributed AI at the edge by using accelerated hardware and sophisticated software to support local AI model training using federated learning. Our solution aspires to reduce the complexity of the connecting vast number of heterogeneous devices through a flexible SDNenabled middleware layer. It also aims to design, develop, and integrate novel, intelligent IoT devices such as smart glasses, haptic devices, energy harvesting modules, smart animal monitoring collars, AR/VR environments, and autonomous drones, to support new market-oriented use cases. Great expectation of the proposal is to foster AR/VR contextual computing by demonstrating applicable results in realistic use cases by using cutting-edge IoT-enabled AR/VR applications. By designing and implementing an IoT-driven decentralised and distributed blockchain framework within manufacturing, TERMINET aims to support maintenance and supply chain optimisation. Our solution intends to apply a vertical security by design methodology by meeting the privacy-preserving and trust requirements of the NG-IoT architecture. To foster standardisation activities for the IoT ecosystem, TERMINET will provide novel disruptive business models. For the evaluation of its wide applicability, TERMINET will validate and demonstrate six proof-of-concept, realistic use cases in compelling IoT domains such as the energy, smart buildings, smart farming, healthcare, and manufacturing.

  • CUREX (seCUre and pRivate hEalth data eXchangE)​ Blockchain

CUREX is an international research project  funded by the Horizon 2020 Programme of the European Commission addresses comprehensively the protection of the confidentiality and integrity of health data by producing a novel, flexible and scalable situational awareness-oriented platform. It allows a healthcare provider to assess the realistic cybersecurity and privacy risks they are exposed to and suggest mathematically optimal strategies for addressing these risks with safeguards tailored specifically for each business case and application. CUREX is fully GDPR compliant by design.​

  • CrowdHEALTH (Collective wisdom driving public health policies)

CrowdHEALTH is an international research project partially funded by the Horizon 2020 Programme of the European Commission that intends to integrate high volumes health-related heterogeneous data from multiple sources with the aim of supporting policy making decisions.

Other Projects 


  • Virtual Reality in Medical Training (EU Erasmus Plus)

A core need for medical students and residents is the hands on acquisition of pre-clinical and clinical skills, which is one of the most resource intensive endeavours in medical education (e.g. Anatomy, Surgery). Physical tangible resources and opportunities for such training are objectively inadequate due to the cadavers’ shortage worldwide. There is a clear need for quality immersive medical simulation resources and episodes. In order for surgical residents to obtain and therefore improve their operative skills and experience, it is best to learn and practice before and after patient encounter. Using tangible (3D prints) or intangible (AR/VR/MR) educational resources in these educational encounters we can achieve far superior immersion and support excellence in training and patient safety.

  • Chatbots Enhancing Medical Curiccula (EU Erasmus Plus)

The aim of CEPEH strategic partnership is to co-design and implement new pedagogical approaches and in particular chatbots for European Medical and Nursing schools. The CEPEH will use participatory design to engage stakeholders (students, healthcare workforce staff, lecturers, clinicians, etc.) in order to co-design effective chatbots and release them as open access resources. Through CEPEH effective use of digital technologies and open education will be incorporated into healthcare curricula. This will enable students to increase their health and medical related skills from offering flexible learning.

Project Number: 2019-1-UK01-KA203-062091


  • ACoRD(EU Erasmus Plus) Advancing Co-creation of RLOs (Reusable Learning Objects) to Digitise Healthcare Curriculum

ACoRD is a project funded by Erasmus Plus Capacity Building in the field of Higher Education (CBHE) and cofunded by Erasmus +Programme of the European Union. It is led by Prof. Heather Wharrad and her team from the University of Nottingham, UK. The partner universities include three universities from Malaysia: University of Malaya (UM), University Putra Malaysia (UPM) and Taylor's University (TU), one from Norway - University of Stavanger (UiS) and Karolinska Institutet (KI)  from Sweden. 

The aim of the project is to introduce innovative digital pedagogy methods that will benefit healthcare and biomedical science students in the partner countries, by sharing existing expertise and training academic staff and technologists in those countries about how to develop high quality, peer reviewed multimedia digital tools and resources and integrate them into existing traditional curricula.
