Education and Careers

The piece I posted a few days ago about the effect of recent cuts in Astronomy funding by the Science and Technology Facilities Council (STFC) has generated quite a lot of comment so I thought I’d try to open up the debate by adding a few comments of my own. I’ve made some of them before and I know many of my colleagues disagree entirely with them, but I think they might prove useful in stimulating some further dialogue.

Of course the backdrop to this discussion is the decision by STFC to impose heavy cuts on the funding it sets aside for the “exploitation” of astronomical facilities. This funding, primarily in the form of research grants awarded to University groups, is used among other things to support early career researchers as postdoctoral research assistants on short-term contracts. Although its own advisory panels were unanimous in placing such funding the highest priority in the recent consultation exercise, STFC Executive  nevertheless decided to impose additional cuts this year. This decision, made very late in the cycle of grant awards, has led to many groups having their budgets slashed from 1st April 2010. Many young researchers facing a very uncertain future, with many of them facing redundancy in a few months.

The fallout from STFC’s financial collapse  has brought to a head a crisis that has been brewing for several years, but in my view it is symptomatic of wider problems within UK science as a whole. There are many problems, but I think the biggest problem with astronomy in particular is that we drastically overproduce PhDs. Even in times of plenty there were too many people competing for too few postdoctoral positions. Now that STFC has decided it wants to cut the number of working astronomers by more than 25% this looming problem has become a full-scale disaster. Many of the most talented scientists in the UK are certain to leave for greener pastures and few will ever return.

The argument I’ve heard over and over again is that training so many people to the level of a PhD in astronomy is good because the skills acquired will benefit the wider economy as those that fail to find a job as a postdoctoral researcher move into other areas, such as finance or industry.

I am not convinced by this argument. I think what we’re doing is producing large number of highly intelligent yet extremely disgruntled scientists who feel – quite rightly – that they’ve been duped into taking on a PhD when they are unlikely to be able to make use of it in their future careers unless they go abroad.

What we’re also doing is deluding ourselves about the quality of a PhD. The UK system produces too many PhDs who are not sufficiently experienced or skilled to take the next step onto a postdoctoral position. Of course there are exceptions, but generally speaking we produce too many PhDs too few of whom have any realistic chance of making a career in science research. The reason for this is that despite the introduction of 4-year degrees in subjects like physics, the UK undergraduate degree is not fit for the purpose of training a scientific researcher.

You may find that harsh, and maybe it is, but I think it’s true.

What I think the UK economy does require is more science graduates (including more physicists) rather than more science post-graduates. I believe we need a radical overhaul in the entire system of science education from undergraduate  through to postdoctoral level.

I have said it before and I’ll no doubt say again that I think we need something similar to what the Bologna process is designed to achieve. This essentially means a 3-year Bachelors degree, followed (for some) by a two-year Masters, then for a subset of them a 3 year PhD.

I think the structure of funding for university courses needs to change in order that we produce more graduates with BSc degrees. Passage from that qualification to a MSc should be highly selective, so fewer such degrees would be awarded. The final selection to a PhD should be more selective still. I’m sure the influx of MSc graduates this system would generate into the wider economy would produce a greater benefit to society as large than the current system, and at a lesser cost.

I’d suggest that in the particular case of astronomy we should be producing about half the PhDs nationally that we do at present.

What about the next step, the postdoctoral research assistantship or fellowship? I hope that STFC can be persuaded to reverse its recent savage cuts in the budget that supports such positions but the government and STFC Executive are showing no inclination to change their position. The current situation for PDRAs is grim. The number of positions available is small and funding for these is insecure.

My first suggestion will probably lead in time to a reduction in the number of  people competing for postdoctoral positions but will not in itself make a career in science seem more attractive.

I think the government also needs to guarantee the stability of  research grant funding over a longer timescale than the current 3-year cycle. Rolling grants used to do this, to some extent anyway, but these have for all practical purposes been abandoned by STFC. I think we need ring-fenced protection for grant funding to be installed at a high level of the Research Council structure to prevent individual research councils playing God with the careers of junior scientists.

I don’t in fact have a problem with the principle that scientists should serve apprenticeships in the form of fixed-term contracts as postdoctoral researchers. What is wrong is that the instability of current funding makes survival in the current system a lottery.

And finally, though it doesn’t really fit with my other comments, I have some advice for young scientists. Your best chance of securing a permanent job in the long run is by being good, not by being shy. Put yourself about. Get involved in teaching – you’ll almost certainly need to do it in a future career, so embrace it. Do outreach work. Work hard at your research. Believe in yourself.

If you don’t, nobody else will.

Scientiae Doctores

Posted in Science Politics with tags , , , on February 22, 2009 by telescoper

The season for recruiting new research students is well and truly upon us and at the same the Science & Technology Facilities Council (STFC) is consulting about changing the way that it allocates PhD studentships to departments.

Most postgraduate students studying for PhDs in Astronomy are funded by STFC (although some Universities also fund their own internal studentships). The result of this arrangement is that successful applicants to a PhD course can receive a stipend which amounts to about £13K per annum. It’s not a huge amount of money, but it is a stipend rather than a salary so it’s tax-free. Since a PhD student also remains a student and therefore qualifies for various other fringe benefits (Council Tax, student discounts, etc), it’s not actually a bad deal for the student. Anyway, if it were significantly more then it’s possible PhD students would have to start paying back their student loans, which would make things worse. STFC also pays a tuition fee to the University concerned, but this is done directly and the student doesn’t even see that element of the funding.

Since about 1995, PPARC and then STFC has funded research studentships in areas within its remit by means of peer review. Departments have bid for studentships (every two years) and a panel awards an allocation depending on the quality of the bid. Of course, everyone asks for many more studentships than are available so what you get is a fraction of what you ask for. I wrote the application for the first ever quota studentships for the Astronomy group at the University of Nottingham, and did it again a couple of times after that. Each time, despite going into best bullshit mode to write the case, I was frustrated by the relatively small number of studentships we were awarded. Although we succeeded in building up gradually from zero to 2-3 per year, it was a very slow process.

In recent years, the funding mechanism has evolved slightly so that studentship fees and stipends were devolved to the departments concerned in terms of Doctoral Training Grants (DTGs) rather than being administered centrally by PPARC/STFC. In the old days, students used to get their stipend from PPARC/STFC whereas now they are paid by their department from a cash grant.

Anyway, for various reasons (chief among them being no doubt to save administrative costs) STFC has decided to consult on changes to the mechanism for allocating the DTGs to the various departments around the country. The most serious proposed change is to follow the practice at the Engineering and Physical Sciences Research Council (EPSRC) and dispense with peer review. Instead, the proposal is to award studentships based on a formula involving how successful the department is at obtaining postdoctoral research assistant (PDRA) support from STFC.

Here is the proposed formula:

 Specifically, the studentship award per department should be proportional to the product of volume and average quality per academic within the department, that is to:

 

V * Q

 

The Committee has followed guidance in developing measures of V and Q that are non-subjective, repeatable and transparent.  The volume V is defined as the number of academics (including Fellows) eligible to hold STFC research grants. The  quality Q is measured by the number of STFC-funded PDRAs (P) awarded per academic (i.e. P/V), since this measures the success of the academic staff in securing STFC funding for PDRAs through peer-review.  More precisely we define quality per academic as Q = [1 +(P/V)].

 

Although the Committee felt this definition of quality applied primarily to responsive-mode PDRAs, it agreed that PDRAs on project grants should be included, but with a weighting, relative to responsive-mode, of 0.33.

 

Using these definitions, the Committee recommends that the studentship award per department should be proportional to a simple product of volume and average quality per academic within the department, that is to:

 

N(students) µ V * Q

 

where Q = [1 + (P/V)]

 

And so the departmental quota is proportional to: 

 

V[1+(P/V)] = V+P

 

In addition, recognising that very small departments offer more limited training opportunities on their own, a threshold is proposed, such that no studentships are awarded for V < 3. Instead, these very small departments/groups would be able to collaborate with other larger departments in seeking STFC studentship support.

 

Hence

 

         N(students) µ V+P  for V ³ 3

                             = 0        for V < 3

 

The constant of proportionality is chosen such that the total number of studentships equals the number available for allocation.

 

 

I think this is a fairly reasonable proposal, actually. The one thing I don’t really understand relates to the fact that STFC doesn’t just fund PDRAs on its grants, but under the Full Economic Cost regime (FEC), it also pays for fractions of academic staff effort for people working on its projects. On my recent successful STFC grant, for example, I was awarded 25% of my time (i.e. 0.25 FTE, full-time-equivalent) to do the research as well as a PDRA. Since the proposal above will have to cope with the question of what staff are “eligible” then why not make the quantity V proportional to the total FTEs funded, or at least only count those for whom some FEC time is allocated? And why not include staff FTE in the Q-factor too?

My guess is that such a modification wouldn’t make much difference to astronomy departments, but the original proposal has caused cries of anguish from particle physicists. This is because the number of PDRAs in particle physics is much smaller than in astronomy, so many large groups face a big reduction in their PhD quota. Including FEC numbers in the mix might well smooth the transition for them. For your information, the number of PDRAs per active astronomy researcher  is around 0.5 at present.

Anyway, the deadline for consulting on this has passed (on February 20th) so we now wait to see what STFC actually does. Probably the consultation period is a purely cosmetic exercise anyway and what will emerge is exactly what was proposed.

If you ask me (and nobody did), all this is mere tinkering. I think there are serious problems with graduate funding in the UK and these require much more radical remedies. At the risk of (and indeed with the intention of) being provocative, here is my diagnosis and suggested remedies:

  • There are too many PhDs in astronomy. STFC funded 160 studentships in 2006, compared with 88 in 2000. There are nowhere near enough PDRA positions to accommodate this number of PhDs in academic research. And even those who get their first PDRA position have very limited prospects of getting a permanent job. The result is a generation of disaffected students employed as low-paid assistants for 3-4 years and then thrown aside when they have got their PhD.
  • Of course, applicants for PhD places don’t know what research is really like and some will leave academia of their own volition when they find out that it’s not for them. In my experience, though, most graduate applicants simply don’t realise how heavily the odds are stacked against them. Less than one in ten can possibly stay in research in the long term, and the more PhDs are funded the worse the odds against them become.
  • The short duration of a British PhD disadvantages our students with respect to those from the USA or continental europe, who all do a lengthy Masters course before taking their PhD. These take at least 5 years to complete.  The result is that our home-grown PhDs are seriously disadvantaged in the job market against competitors from abroad. Similar points have been made forcefully by Ian Halliday.
  • My remedy is simple. Reduce the number of studentships but extend each one to five years and require each hosting department to provide a proper graduate school with intensive graduate-level courses to make up for the progressive reduction in content of undergraduate physics courses.
  • Even more unpopularly, I think the UK should scrap 4 years Masters (MPhys) programmes and embrace the structure of the Bologna agreement, i.e. a universal 3+2+3 structure of 3 years Bachelors, 2 years’ Masters and three years PhD.
  • Currently STFC stipends can only be paid to UK nationals and residents. It’s an open secret that most departments would preferentially recruit European physics graduates to their PhD positions if they were allowed to do so, because their undergraduate preparation is much better than that provided in UK universities. I propose that we abandon this protectionism and open up PhD opportunities to European applications, just as we would legally have to do if a PhD were considered to be a job.
  • Finally, I think the UK should consider the introduction of a common graduate entrance examination, perhaps based on the US GRE, to ensure the maintenance of appropriate standards for postgraduate entry and eligibility for STFC funding.

There are of course some advantages to the current British PhD system. For one thing, the PhD is earned very quickly. I was 25 when I got my PhD, and already had several publications. Most of my European collaborators were at least 30 before they got theirs (additional years have to be added for national service in many countries, but we don’t have it in the UK). But I am painfully aware that my technical knowledge outside the immediate area of my PhD is much thinner than most academics in the field. Now, in middle age, I feel like a long-distance runner who had inadequate preparation, went off too fast at the start of the race, and is now struggling along while people overtake him with monotonous regularity.

The nature of research in astronomy and cosmology has changed so much in the 20 years since I got my PhD that the old system has to go. Instead of tinkering with funding formula, driven principally by the need to save adminstrative costs within STFC, we need a radical overhaul of the entire graduate education system in the UK, involving all research councils and their political masters.

Unfortunately, though, for the time being at least the politicians have other more pressing matters to worry about, such the collapse of the economy.
