PhDs in Data Science and Governmental Resource Allocation

Hello

I am a student at the University of Tasmania, who is interested in doing research in government allocation of resources. I have a background in data science, not economics, so I do not qualify for PhD projects at the Global Priorities Institute and similar organisations, however I nonetheless really want to do a PhD in resource allocation, and there has to be some way in which a data science background (statistics and computers, not to mention the methodologies of science as such) allows me to get into this. Does anyone have any ideas?

Thank you in advance.
Jack
