Robust Techniques in Quantitative Finance

University of Oxford, 3-7 September 2018


Since the seminal work of Knight, the distinction between risk and uncertainty has played a crucial role in Economics and Finance. Robust methods address the latter and, in the wake of the financial crisis, their importance has been increasingly appreciated. In particular, such questions and the corresponding mathematical techniques became one of the most active fields in Mathematical Finance.

The conference will bring together an interdisciplinary group of researches with interests in Financial Mathematics, Finance and Economics, with model uncertainty as the unifying theme. It promises to be an exciting meeting exploring the state-of-the-art, future directions and offering space and time for discussions and interactions.

This meeting follows in the footsteps of three previous meeting which we have organised in Oxford in 2010, 2016 and 2017. While the previous ones were two days focused workshops, this time we organise a much larger and broader 5-day meeting.

Thank you

We are grateful to all who participated and thank you for the wonderful feedback we have received after the conference. The meeting was truly inspiring and we look forward to all the new research that comes out of it!

Venues: Conference, Social events, Accommodation

The meeting will be held in the Mathematical Institute, University of Oxford which offers world class conference facilities in the heart of Oxford. There will be a wine reception on Monday evening in the Common room. The conference dinner will be held on Tuesday in St John's College Oxford. Punting will be organised at the Magdalen bridge on Thursday.

Most participants who were offered accommodation, or booked it via the online store, are staying at Keble College. Unless we emailed you to say otherwise, please assume you are staying at Keble. Please check in at the Porter's Lodge (located at the main entrance to the college on Parks Road, OX1 3PG, T: 01865 282505, see map). The Porter's Lodge is manned 24 hours a day. Checkin time is 2pm, check out is 10am (but you may be allowed to check in early or check out late if rooms are not being used and, in any case, they can store your luggage). Subject to our pre-booked capacity, delegates staying in standard rooms may be upgraded free of charge to en suite rooms.
