David is associate professor of information systems, and former vice-chairman, at the Graduate School of Business Administration of Bar-Ilan University, Israel. His research has appeared in publications such as Information Systems Research, IEEE Intelligent Systems, JASIST and ACM Computing Surveys. His books include Cooperating Heterogeneous Systems; Internet-Based Knowledge Management and Organizational Memory; and the Encyclopedia of Knowledge Management, now in its 2nd edition.

David was visiting scholar at Columbia University (2004), Monash University (2007-8), Victoria University (2016), National TsingHua University Taiwan (2017); and awarded a Visiting Erskine Fellowship at Canterbury University, New Zealand (2016). His research interests are Cybersecurity, mHealth, Knowledge Management, Social Network Analysis, and Computer-mediated Communications. Current Research Statement In 2013, witnessing the convergence of mobile smartphone technologies and social networks to form location-aware social platforms, and an awareness of the demands of medical emergency response, led me to propose the creation of Emergency Response Communities (ERC). The guiding observation behind this research was the fact that in certain emergency situations when a key life-saving medication is lacking, it can be sourced faster from a dedicated smartphone-based social network of like-patients than from EMS. I turned to a number of leading medical experts to join me and provide medical guidance for this new initiative including Prof. Dr. Abdel Bellou (former president of the European Society for Emergency Medicine and currently Disaster Medicine Fellow at BIDMC/Harvard), and Prof. Dr. Nikos Papadopoulos (president of the European Association for Allergy and Clinical Immunology) along with other leading figures in Emergency Medicine and the field of Allergy and Immunology. The first target intervention became the supply of adrenaline auto-injectors in incidents of anaphylaxis, which we continue to study and develop in collaboration with Israel's national EMS (Magen David Adom).

Despite barriers which include pharmacovigilance guidelines, legislative restrictions to medication sharing, and uncertainty regarding intervention efficacy by laypersons, we continue to push the envelope in what can be a paradigm shift for emergency response for certain chronic conditions. My search for high-impact target medical conditions led me to a collaboration with addiction sociologist Dr. Steve Lankenau, through which we have mapped out the innovative opioid overdose-reversal intervention being studied through a recently-awarded NIH grant, using the principles established for ERC. Our flagship UnityPhilly project is defined as a clinical-trial of an emergency intervention app, studying the impact of life-saving medication sharing. This grant has recently been expanded to include study of wrist-worn biosensors with potential for automatic overdose detection.
