I am an Assistant Professor of Biomedical Informatics in the Department of Biomedical Informatics at Columbia University. My primary research interests reside in the areas of Biomedical Informatics, Human-Computer Interaction, Ubiquitous and Pervasive Computing, and Computer-Supported Collaborative Work. My broad research interests include individual and collective cognition, sensemaking and problem-solving in the context of health, health care, and health management. My research group, Action Research for Collective Health (ARCH) views health and health management as residing within families, communities, and societies, and as impacted by culture, business, and policy. In ARCH, we develop novel technologies that help individuals to take a proactive stance towards their own health and to change their environment to make healthy and responsible lifestyle accessible to everyone. At the same time, I am interested in the functioning of the healthcare system and in the ways it adapts to the changing demands and expectations of the society. I study how clinicians collect and use information to make decisions in regards to patient care, how clinicians on patient care teams communicate and coordinate their work and make decisions together, how clinical communities share knowledge and expertise, and how computing technologies facilitate or inhibit these processes. I received my B.S. in Computer Science from the Ukrainian State University of Maritime Technology, M.S. in Human Computer Interaction from the Georgia Institute of Technology, Ph.D. in Human-Centered Computing from the Georgia Institute of Technology, and M.A. in Biomedical Informatics from Columbia University. My dissertation work at Georgia Tech focused on facilitating reflection and learning in context of diabetes management with mobile and ubiquitous computing. Prior to joining DBMI as a faculty member, I completed a National Library of Medicine Post-Doctoral Fellowship at the department.
