Background & Research Interests

I am a Senior Lecturer in Digital Health at the University of Melbourne's School of Computing & Information Systems and the Centre for Digital Transformation of Health.  My research interests are centred on the application of computational methods — particularly natural language processing — to public health research questions, with much of my research output focused on the broad areas of communicable diseases, mental health, and substance use.  In addition to my computational work, I also publish on ethical and socio-technical issues associated with the development of digital health technologies.

My research has been funded by the United States National Institutes of Health (National Library of Medicine and National Institute on Drug Abuse).

Prior to joining the University of Melbourne in 2021, I held research positions at the University of Pittsburgh, Mayo Clinic, the University of California San Diego, and the University of Utah.

Potential PhD Students

I am currently interested in recruiting a PhD student with strong computational skills and an interest in social science to work on the role of companion and therapy animals in health outcomes.
