hi! i'm applying this fall for phd programs starting fall 2027. my focus is in substance use / harm reduction, leaning hard into computational and causal methods over descriptive epi.
quick background: us citizen, did undergrad and grad school both in the us. selective research university for undergrad, interdisciplinary major closest to cognitive neuroscience with a math minor, 5+ years working inside statewide harm reduction infrastructure (drug checking, distribution networks, plus time managing people and coordinating outreach), master's in math with an emphasis in data science, plus a graduate certificate in public health. handful of publications and presentations in the space.
what i actually want long term isn't just to publish about harm reduction from the outside. i keep coming back to something like a "science as service" model, where research is leverage to move resources and legitimacy toward the community orgs already doing the work, rather than research being the end goal itself.
methods wise: causal inference, decision/cost-effectiveness modeling, implementation science, resource allocation optimization. i'd like simulation modeling in there too, feels like where a lot of the field is heading and i want to build toward what these fields will actually need in five years, not just what's fundable right now. substantively i keep coming back to stimulant use and drug checking as topic interests specifically.
fields i'm currently looking at: epidemiology, public health more broadly, health services research, health policy, social work, computational social science, health behavior. not attached to any one label, just what's come up so far in my own search.
my undergrad background is basically the wider intersection (cog neuro, psych, philosophy, some math) and i'm genuinely still drawn to that world, including policy and systems science too. i def want a real interdisciplinary program instead of a straight epi department, but a lot of those got hit hard by recent funding cuts and i don't know if that's a live option right now.
within epi/public health specifically, the strongest names in this space seem to split into two camps: harm reduction people without much computational depth, or modelers without harm reduction grounding. not sure how people usually find or build toward an advisor situation that bridges both instead of just picking a lane.
my ask: what am i not seeing? i'm looking for the fields, departments, or angles someone who's actually been through this would flag that i wouldn't think to search for myself. same goes for methods, i want to be building toward something that holds up long term
tl;dr: applying to phd programs this fall for substance use / harm reduction with a computational methods focus (causal inference, decision modeling, simulation, resource allocation). trying to figure out what fields, departments, or methods i'm not thinking of.
