ECSTATIC (Early Career Stage Topologists AT Imperial College)


Invited speakers:

Andrew Ranicki (University of Edinburgh)
Liam Watson (University of Glasgow)

ECSTATIC was a two-day conference at Imperial College, aimed at young researchers (Ph.D. students and postdocs) working in or interested in all forms of topology. All participants were encouraged to present their own research or the field they are working on by giving a talk.

Dates: 11th-12th June 2015
Venue: Imperial College London, South Kensington campus, Huxley building, Clore Lecture theatre

Registration to the conference is now closed.

Guidelines for giving a talk

  • Talks are to be 25 minutes long for Ph.D. students and 40 minutes for postdocs.

  • Please bear in mind that although topologists, attendees will be working in different branches of the field. As such, talks should aim to be understandable on an overview level by non-specialists.

  • The lecture theatre is endowed with a projector. Should you give your presentation through a slide show, please email the file beforehand to one of the organisers (pendrives usually work too, but sometimes the computer does not read them).

Some limited funding is available for attendees, and we are still actively looking for more funding. We hope to cover the accommodation costs and travel costs entirely, but at the moment we can't guarantee that.
Participants are anyway encouraged to try to find alternative fundings to help us ensure as wide a participation as is possible.

For those of you with childcare commitments, do not forget the LMS Childcare Supplementary Grants.


The attendees who registered before 1st May and asked for accommodation will stay at the Westpoint hotel, 168 - 172 Sussex Gardens Paddington, London, W2 1TP. The attendees staying at the Westpoint hotel should have already received a confirmation email from the organisation.

A map showing the route from the hotel to Imperial College is available here. This will also be included in your registration pack.

Travel Information

The venue of the conference is the Clore Lecture t heatre of Huxley Building (Imperial College London), located at 180 Queen's Gate, SW7 2RH London. 

View detailed directions to the venue

The closest underground stations are South Kensington and Gloucester Road, both on the Circle, District and Piccadilly lines. A journey planner (TfL journey planner) is available on the website of Transport for London.

We strongly advise obtaining an Oyster card for travel in London - it halves fares in general, and automatically charges minimum fares. Those in possession of 16-25 railcards can link them to their Oyster card for even lower fares - and the £5 deposit is fully refundable. They are available at most underground ticket machines.

Reaching London from the UK

The cheapest way to reach London is often by coach:< /p>

London is also very well serviced by rail. Check the journey planner of National Rail Enquiries, which are cheaper if booked in advance.

Reaching London from abroad

London is served by many airports as well (London City, Gatwick, Heathrow, Luton, Stansted). While London City and Heathrow airports are connected to the underground network, Gatwick, Luton and Stansted can only be reached by bus or train. For more information please follow this link.

If coming from Western Europe, another option to consider is train: the Eurostar runs from Paris or Brussels into London and can some times be more affordable (and p leasant!) than air travel.



Should you need to contact one of us, please send us an email :, where x \in {t.hockenhull13, m.marengon13} or, where z = Fyodor's last name.
