Dr. Shachak holds a PhD in Information Science from Bar-Ilan University, Israel. His research explores various interventions to improve use of information and communication technology in health care and biomedicine and help realizing the potential benefits of these systems. This work includes the study, design, and evaluation of educational interventions, tutorials and user manuals, user interfaces, and end-user support. The work he led on the impact of electronic health records on patient-clinician communication, and clinicians’ adaptation to the challenges involved, has informed the design of several simulation-based educational interventions. Dr. Shachak is also interested in patient engagement through the use of information and communication technology (ICT) and particularly the interrelationships between patients' preferred roles in decision making, health information literacy and use of information resources. This work seeks to inform patient engagement initiatives to ensure that they meet patients and families’ needs and preferences. Dr. Shachak’s work has been published in various Medical, Information Science, Medical Informatics, and Technical Communication journals and conferences.
