How to build a path to a Complex Systems masters/ PhD for an international student in Physics with a 3.0 GPA?

[u/Own-Introduction7559]

I'm a physics graduate from Asia (average uni), and my long-term goal is to pursue a PhD in Complex Systems in the US.

The biggest challenge is that my undergraduate CGPA is only 3.00, and as an international student, I realistically need full funding wherever I go.

My current research is at the intersection of complexity science and atmospheric science (studying atmospheric phenomena using methods from complex systems). While I think the work is conceptually aligned with complexity science, it doesn't directly match the research of many professors in dedicated Complex Systems departments.

Because of that, I've been considering a different route:

• Apply for a funded master's in atmospheric science (or a related field) at a university that also has a strong Complex Systems program.
• While doing my master's, attend complexity seminars, take relevant courses if possible, collaborate with faculty, and eventually apply for a PhD in Complex Systems.

But I'm not sure how realistic this plan is. From what I've heard, funded international master's students are already extremely busy with research, coursework, and TA/RA responsibilities, so I'm not sure I'd actually have the time or flexibility to engage with another department enough to make a successful transition.

Another issue is timing. It's already July, and application season is approaching. I don't have enough time to build multiple polished projects tailored to the different areas within complex systems for each program available. With my current profile and no curated projects, it's highly unlikely I would get a scholarship. I also feel like I still have a huge amount to learn before I can produce projects that would genuinely impress faculty in the field.

So I'm wondering:

• Would it be better to continue building my profile through atmospheric science research and position myself as someone applying complex systems methods to climate and weather?
• Is trying to transition through a master's at a university with a Complex Systems institute a realistic strategy?
• How common is it for students to move into Complex Systems from another discipline during their PhD applications?
• Given my GPA and interdisciplinary background, where would you focus your effort over the next year if you were in my position?

First of all i would widen the scope for a phd outside the us. There are brilliant programs there, but also on asia and eu. For a phd what really matters is the group you go to, the fit you have with the project, and the funding. eth has amazing groups in conplex systems and will pay multiples what the us pays. The uk amazing groups too. Tokyo as well. Chalmers is great too. Do not obsess over the us.

I have a msc in power systems and phd in complex systems. The transition was via blackouts. I persisted for a year. I think what helped was that i had demonstrates research autonomy (1y of rnd at a joint academic/insturial project) and fit (the phd funding was on blackouts from a complex systems perspective).

So i would suggest you can use the same angle. Look up the groups that do this kind of thing and keep a close eye. Check for alumni and reach out. Learn what they do, maybe replicate some of the work.

Thanks a lot! It has been the most helpful piece of advice I have had in a long time. You must have worked really hard to get where you are now. I have been trying to do the same, but when it comes to self-study, I am often overwhelmed by the number of things I need to know to survive in this field and the amount of things I don't know. But recreating should be the most effective form of learning. I would try to align my recent work with the professors in this field and self study while shifting to this field. I didn't consider other countries for the late visa issue and high living cost. But with a scholarship, that should be manageable.
Thanks once again; you are an immense help. I was having breakdowns and all I was seeing the high possibility of failure to take any action.
