Current Ph.D. Students
Going to conferences
It is very important that you attend lots of conferences during your Ph.D.. Conferences are an opportunity for you to do several things;
- Expose yourself to new ideas in your field. Stagnation is death.
- Develop your networking skills, and attract collaborators.
- Develop your public speaking skills.
- Foster interest in your research.
- Expose yourself, your research and your research group to expert criticism.
- Seek employment opportunities if you plan to stay in academia.
- Travel the world, and leave not a cent of grant money unspent!
There are a few conferences on the horizon;
- Rencontres de Moriond, 18th-25th March 2023. Moriond is a recurring conference divided into blocks (18-25/03 : Electroweak Interactions & Unified Theories 18-25/03 : Gravitation 25/03-01/04 : Mesoscopic Physics 25/03-01/04 : QCD and High Energy Interactions). The application deadline has passed (31st January) but there may still be space.
- I've heard a rumour of something in-the-works to be organised by Jose Beltrán Jiménez in Salamanca. Watch this space, and I'll update...
- There will be a conference `complex' taking place in the summer of 2023, as organised by the Corfu Summer Institute.
- The 32nd Texas Symposium on Relativistic Astrophysics is supposed to be held in Shanghai, but as far as I can tell it does not yet have a website. Last year it was in Prague.
Prospective Ph.D. Students
This fall (2022) I will be advertising a Ph.D. position, to be jointly supervised with other group members. Research themes will include gravitational theory, quantum gravity and modified gravity. The advert to appear on the Cavendish Astrophysics Ph.D. topics page will run as follows:
W Barker, M Hobson & A Lasenby: Gravitational theory and quantum gravity.
- Fundamental theory of the gravitational interaction: gauge-theoretic and geometric formulations (torsion, non-metricity); canonically-driven methods; theoretical constraints on less conservative formulations (e.g. relativistic MoND, gravity as an order parameter of the fermion vacuum).
- Perturbative quantum gravity: particle spectra in strong backgrounds; effective field theory of gravity.
- Non-perturbative quantum gravity: lattice regularisations including dynamical triangulations; novel applications of geometric algebra.
- Phenomenology of modified gravity: classical dynamics and exact solutions; cosmological perturbation theory; primordial non-Gaussianity and shape templates; parametersised post-Newtonian formalism; detection of non-Riemannian geometries; implications for fermion physics. Links with cosmological inference, numerics and computation in W Handley's group.
- Computer algebra: use of high-performance computing to solve symbolic (non-numerical) problems in gravity theory; surveying the theory-space for viable Lagrangia; theory-agnostic tools (HiGGS, PSALTer).
In general, these topics need not be binding or exhaustive if our research interests align on some other project. These matters could be discussed at the informal "interview" or via email.
For most applicants...
The main bottleneck for obtaining a PhD in the UK is securing funding, which for international applicants is especially competitive as there are not many funds which can cover the higher University fees. If there are any independent funding bodies from your home country or otherwise from which you can secure support to fund or partially fund your degree, then this will substantially improve your chances of finding a PhD place in the UK. There are also language requirements for international students, for which Cambridge is higher than usual (unfairly in my view).
For most applicants (home and international), the deadline for securing funding from the University itself will dictate the application deadline, and this will be midnight on the 1st December, 2022. I'd strongly recommend you submit all components of the application at least 24 hours in advance, due to potential ambiguities over the cutoff.
The rest of this information is based on the Cavendish Astrophysics Group Graduate Research Opportunities for October 2023 entry page, which links to a description of the admissions procedure.
You must apply through the University-wide Board of Graduate Study (BoGS). A good place to start is from the advice on postgraduate application deadlines. From there you can establish your funding deadlines from the information page on how to find funding. The most relevant funding sources are consolidated into something called the Cambridge Trust: the Trust deadline is what establishes the 1st December deadline above. The Trust allows you to search for available scholarships. Particularly relevant to overseas applicants is the Gates Scholarship. Gates has a rather extensive application process. There may well be other (departmental or college-specific) funding sources that are not part of the Trust. For UK applicants, note that the BoGS application procedure causes you to be considered for STFC funding (i.e. UK government funding).
You must also apply directly to our research group (departmental application), and for this there is a dedicated application form. You should do this by the same application deadline as above, December 1st. Unhelpfully, I learned last week that the form is out of date since last year, and neither Professor Hobson's name nor my own are listed where it says "Please select the name/s of the main contact person/supervisor you would be interested in working with". For the time being, you should select "Will Handley", and make it clear that you are applying to the Barker/Hobson/Lasenby abstract in one of the three funding information boxes at the end of the form, and also email the administrator at email@example.com. We will then redirect applications at our end.
Once the applications are submitted, informal "interviews" will follow.
For a small minority...
For those of you who have some external source of funding available (not associated with the University, Cambridge Trust, etc.), you will notice that many of the links above mention later deadlines, extending even into the new year. I would still encourage you to register interest and apply by the 1st December deadline.
