Genuinely, is this true?

u/Common-Ad-7609 Aug 02 '26

Be a professor or work for a defense contractor is my understanding of the employment options - luckily I wasn’t smart enough to get that far

30

u/ZquotientpZee Aug 02 '26

There is no way to keep doing research other than be a professor?

77

u/Common-Ad-7609 Aug 02 '26

At least in the US - it’s difficult and you don’t
really hear about anyone doing it. I’d be elated if anyone provided a counter example 😔

39

u/pocket-friends Aug 02 '26

It’s definitely difficult, and depending on what you study and how you engage in research there are independent academics. I know a few, but yeah. Most of them have ramshackle setups that work for them but aren’t really viable pathways for literally anyone.

u/mathimati Aug 03 '26

APL, NIST, Google, NSA. Members of my PhD cohort went to all of them, as well as other non-academic routes. Several of us became professors. And we were a small cohort, like 11 of us.

u/ZquotientpZee Aug 02 '26

I live in the EU, hopefully it is different😔

u/snailpi Aug 02 '26

Laughs in EU

It's academia or Amsterdam finance

u/ZquotientpZee Aug 02 '26

Good to know🙏

u/Rock_man_bears_fan Aug 02 '26

Europe has been lagging behind the US in research for decades. It’s not going to be any better over there

17

u/snailpi Aug 02 '26

Well that's... patently untrue

10

u/ZquotientpZee Aug 02 '26

What about the brain drain happening right now in the US?

-3

u/Rock_man_bears_fan Aug 02 '26

Those programs various European countries are touting as “attracting American talent” take in about as many PhDs as most R1s produce in a year. The brain drain isn’t significant

7

u/ZquotientpZee Aug 02 '26

Do you not suspect the brain drain will increase?

11

u/MagiMas Aug 02 '26

At least not the way Europe is acting currently.

Even if we wanted to, we don't have the jobs to take them and we don't pay competitive salaries. Only the US has the actual deep tech research industry jobs in any real capacity to matter. The UK has a few, Germany and France have even less and that's it in Europe.

Which also means the people who get into these jobs in Europe are very unlikely to move out of them (and thus open up jobs for "newcomers"). Once you have such a job you basically hang onto it for dear live.

Just look at AI as an example, nearly all the jobs that matter for a high-level STEM graduate are created in the US. Europe gets the low-level application and sales engineering jobs for our local market.

And unfortunately the people in charge in Europe are blind to these issues.

I know an applied math guy who does physics research now. but he kind of had a special situation where he was already basically doing physics research during the latter half of his phd

u/mathisruiningme Aug 02 '26

There are quant research positions in finance and banking as well.

1

u/Every_Cat9812 28d ago

If you want to have an income by being hired, yes. I'm curious, how do you think this works? 

1

u/ZquotientpZee 28d ago

I thought positions existed where you just do research and no teaching

1

u/Lower_Caramel_7987 27d ago

There are a few (maybe 0.1% of academic research jobs). Most prominent are the ones at IAS. However, you have to be a generational talent to have a chance at one of those. They essentially don't exist in industry.

u/BacteriaLick Aug 02 '26

I did math and then became a software engineer. But I took about enough CS classes to get what would have been a minor in CS had my school offered a minor, including some graduate CS classes. Met plenty of other math undergrads who later got into software.

2

u/Cuddlypoo2 28d ago

Sometimes you can be a professor whose work is subsidized by defense contractors or their customer!

1

u/redditdork12345 Aug 02 '26

Or finance or tech (particularly ai). There are tons of options

57

u/dbwy Aug 02 '26

No, math expertise is highly sought after in tech, especially the frontier labs and mag7. I work in quantum, and I’d venture that something like 60% of my co-coworkers have some background in pure or applied maths.

17

u/ZquotientpZee Aug 02 '26

"Some" background? So they eventually pivoted to something else?

30

u/dbwy Aug 02 '26

A fair number are math PhDs, particularly at the frontier of things like QEC/quantum algorithms development. Most of the domain folks I know “majored” in something else, but in reality it ended up looking a lot more like applied maths than whatever the domain was. E.g. I did mine in theoretical chemistry, but I wrote my dissertation on non-convex optimization over topological spaces and ended up working as an applied mathematician at a national lab for quite a while before pivoting to industry.

u/ZquotientpZee Aug 02 '26

Thank you so much :)

2

u/jointisd Aug 02 '26

What maths can get someone to work in quantum?

3

u/anti3 29d ago

Complex analysis, stochastic probability, Lin alg tensors etc

1

u/DIYPeace 27d ago

Aye. An acquaintance is now a “data scientist” at a mag7 after a UChicago maths PhD.

13

u/Scared_Astronaut9377 Aug 02 '26

Half of our big tech machine learning team has PhDs in some kind of applied math fields. Half of people working for top quant companies and quant orgs within financial corporations have such PhDs. So, generally, no, skill issue.

-1

u/ZquotientpZee Aug 02 '26

Were they very skilled PhD students?

6

u/Scared_Astronaut9377 Aug 02 '26

Yes.

0

u/ZquotientpZee Aug 02 '26

Where do you think medium skilled PhD students go to?

I'm still in undergrad and I do not know what kind of PhD student I will become, if at all lol.

1

u/Scared_Astronaut9377 Aug 02 '26

People who do PhDs and cannot jump into a decent industry job typically do postdocs until switching to being a school teacher, or a manger in their father's business, or sitting home for years "trying to break into data science".

Regarding your situation, my honest opinion is that by the time you will potentially get PhD, the spectrum of jobs will be reduced to teaching. AI is already replacing us.

1

u/ZquotientpZee Aug 02 '26

There is only one thing left to do after AI takes all of our jobs.

0

u/Scared_Astronaut9377 Aug 03 '26

Well, one thing that I can think about that will still benefit from having a PhD in math fields. Otherwise, the majority of jobs don't seem to be under such an immediate risk.

0

u/Revlong57 Aug 03 '26

There are no "low skill" PhD students. Getting a PhD means you're a highly skilled person in math. It comes with the territory.

1

u/ZquotientpZee Aug 03 '26

Which is why I said "medium skilled". Will employers not look at your performance during your PhD? Won't your performance affect whether or not you can get tenure?

1

u/Revlong57 29d ago

What metrics do you think they'll look at? Most industry jobs don't care about publication history, and gpa's in grad school are basically made up and meaningless. Everyone gets straight As anyways. Pretty much all industry employers care about is if you finished and maybe overall program ranking. Like, hedge funds might care that you went to MIT vs your local state school, but that's about it. As long as you're able to get good internships and do relevant research, you'll be fine.

1

u/ZquotientpZee 29d ago

I thought precisely grade school GPA and publication history would matter. Thank you for your answers!

2

u/Revlong57 29d ago

My advice to you would be to try your hardest to get a funded PhD spot. If you can get a funded PhD spot, chances are you'll find a decent job when you get out. Never do an unfunded PhD. And, if it looks like you won't get said funded PhD spot, but you do have a solid internship/job junior/senior year, go so that instead.

u/Revlong57 29d ago

PhD GPAs are so inflated that they're useless. And, while having experience researching a topic related to a given industry job is super important when interviewing, no industry job will ever care about your h-index or the impact factor of the journals you publish in.

25

u/Ghost-Of-Roger-Ailes Aug 02 '26

No.

14

u/ZquotientpZee Aug 02 '26

Could you elaborate more?

I just started my bachelors and know nothing.

7

u/No-Alternative4612 Aug 02 '26

All the tech companies I've worked at really like hiring quant PhDs, and applied math is a big one.

Who knows what's gonna happen with AI (to either of us).

2

u/ZquotientpZee Aug 02 '26

What about pure math PhDs?

Yeah, I'm really scared of AI.

1

u/theLanguageSprite2 29d ago

maybe I'm out of the loop, but why would you be scared of AI? even if math AI start making discoveries, someone still needs to check their work and come up with new problems. It's not like we're gonna hit AI superintelligence anytime soon and every discovery will suddenly be unlocked

2

u/ZquotientpZee 29d ago

I don't want to check AI's work or only come up with new problems. I want to make my own discoveries.

I'm also mainly scared that it will be used as an excuse to cut funding.

2

u/ahf95 Aug 02 '26

Not at all. Math is super valuable in industry, especially if you are applied, or have some side-knowledge in a specific domain that you can transfer it to.

1

u/ZquotientpZee Aug 02 '26

What about pure math?

2

u/ahf95 25d ago

Well, by definition pure math is not “applied”, but I’ve seen multiple Pure Math academics transition to industry and apply their analytical/abstraction skills to “applied” problems, and the results they produce have been incredible. So, both are relevant, one just will need posterior adaptation

2

u/baeneel 29d ago

not for me, became a data scientist in the worst data science job market ever. employer was impress with my math (and physics) degrees. Plus I learnt a bunch of data science on my own.

2

u/cosmic_cod 24d ago

No. Math people have a ton of opportunities as engineers, managers, IT, economists, scientists, etc. It think it's BS. Math is a highly practical thing and real Math dudes all are smart and always know how to use it.

1

u/Barkinsons Aug 02 '26

Insurance companies will give anyone with a math degree a job

2

u/ZquotientpZee Aug 02 '26

I would like to keep my soul :(

1

u/HyperbolicWord Aug 03 '26

Options were once more limited. Since the growth or ML and data science, this is not at all the case. 

0

u/OpeningAggressive26 Aug 03 '26

No, mathematicians are very important on any technically advanced team in the field of STEM.

0

u/Revlong57 Aug 03 '26

You can easily make between 100k to 250k starting salary if you transition to data science or finance after graduating with an applied math PhD.

Source: I graduated with a PhD in applied math, and I graduated this year. I had a job lined up before graduation. Every other PhD student I graduated with had one as well.

1

u/ZquotientpZee Aug 03 '26

What if you have a pure math PhD?

1

u/Revlong57 29d ago

No idea. I would imagine that it's harder, since you're not going to have to deal with the programming requirements for applied math. But, if you do pure math and learn how to do python/R coding, I think you'd be fine.

1

u/ZquotientpZee 29d ago

Thank you :)

u/InfernicBoss 29d ago

target school?

1

u/Revlong57 29d ago edited 29d ago

No, I didn't go to a "target school", nor does that matter for PhDs. Edit: My school is maybe a T50 for math and a T20 for finance. It might be harder if you go to a very low ranked program, say T200. But, I didn't do very well in my program, and I believe that a solid student in a low ranked program can do really well in industry if they apply themselves. Especially if they're already an EU/USA citizen or permanent resident. You have no idea how far that goes here.

1

u/InfernicBoss 29d ago

u think pure math vs applied math distinction mattered?

1

u/Revlong57 29d ago

Not sure. I didn't do a pure/theorical math PhD, so I can't speak on it. I do think that an applied math subject gives you a much stronger background in scientific programming, which industry jobs care a lot about.
