Is a Cosmology PhD a Dead End or a Gateway to Diverse Career Opportunities?

[susskind_leon]

I've asked a similar question earlier already, but I want to be more specific now.
I'm contemplating doing a PhD in cosmology (mainly numerical analysis of galaxy observations). It's a good group with a good international standing. I'm just a bit worried about the time after my PhD. How specialized in cosmology/astronomy would I be after a PhD in that area? Is there a way to get into a less competitive field like condensed matter, stat. mechanics, cold atoms, ... after that, assuming that I did a good job in cosmo or is the only way to do my PhD in the field that I want to end up in?
Thanks

Sure it draws more people than CM but for good reasons, it is a much more stirring subject. I don't think it is a dead end at all(it's not string theory). Also, it sounds like from the type of research you'll be doing you'd be well positions for non-academic jobs after the Ph.D. if need be.

Hi, thanks for you reply. By dead-end, I just meant, is there a way cosmo -> CM after the PhD, especially taking into account that I've been working numerically a lot or will I be committed to cosmo forever?

Having done a PhD in observational / numerical cosmology, I do not feel at all qualified for any kind of industry job in condensed matter or related fields. I've done nothing at all in those fields; I'd be as useless as an undergrad (no offense to undergrads).

If you work on something heavily numerical (i.e. massive galaxy formation simulations), that gives you computational skills that are marketable elsewhere. Also it's not hugely difficult to move from one heavily computational field to another (i.e. numerical cosmology -> CFD or numerical finance.)

The problem with cosmology is that when people think cosmology they think big bang and string theory, which moves things away from the problems which I think are more interesting and useful.

Well how could you expect most people to think any differently? Anytime I have searched on the internet or read anything in a science magazine about cosmology more often than not they are talking about inflation, big bang nucleosynthesis, galactic spiral arms, GRB's, etc...I mean this is what cosmologists study right? Or am I mislead?

I think these subjects are very interesting and captivating to read about, even when I myself may not be interested in pursuing a career in it. Also, I would think(from what I have read) that someone who could get a PhD in Cosmology could honestly tackle anything, and probably has quite a bit of a skill set, hence could go into other fields with not too much trouble. Is this not what cosmology is like?

Just to clarify, I meant quantum gravity and string theory, which has turned out to be useless to cosmology so far. Also there is a lot here that is missing. Galactic evolution and the dark ages are pretty active.

Cosmology gets you some useful skills, but it's not any different from say condensed matter theory or predicting hurricanes. What I think gets missed is that cosmology is an highly experimental area of physics.

What? Do you know so?

I don't think it is a dead end at all(it's not string theory). Also, it sounds like from the type of research you'll be doing you'd be well positions for non-academic jobs after the Ph.D. if need be.

So you have managed to a rigorous rebuttal to String Theory as a candidate then?
