The meeting on 28 May 2020 had the theme of Algebraic Geometry and the speakers were Arend Bayer and Margherita Lelli-Chiesa. Details about the seminar are available at the seminar webpage.
EPSRC   I hold an EPSRC grant with my colleagues Dominic Joyce and Alex Ritter. We appointed Guillem Cazassus as a postdoc on this grant.
CMO-BIRS  I co-organised a 5 day meeting on G2 Geometry and Related Topics at Casa Matemática Oaxaca (CMO), Mexico, with Spiro Karigiannis and Conan Leung. The workshop took place on 5--10 May 2019 and the talks were exclusively given by early career researchers, almost all graduate students, which was a great success.
Oxford   As of January 2019, I am a Professor of Pure Mathematics at the University of Oxford and Tutorial Fellow at Balliol College.
Pint of Science I gave a talk on "The Shape of the Universe" at Pint of Science: Our relatively curvy universe on 20 May 2019 at Farr's School of Dancing, Dalston, London.
El País My article (in Spanish) entitled "Por qué estudio la séptima dimensión" has been published in the Café y Teoremas section of El País in November 2018.
LSGNT   I was the Co-Director of First Year for the London School for Geometry and Number Theory for PhD students, for the academic year 2017-18 and Term 1 in 2018-19. UCL is leading this EPSRC Centre for Doctoral Training, in collaboration with King's and Imperial.
Public policy  I took part in a scheme run by the Royal Society which pairs scientists with MPs and civil servants, including a week spent by the scientists in Westminster which was fantastic. There is a case study of my experience on the Royal Society website and you can hear me discussing some of my experience on the scheme and my other interactions with parliament in a UCL Public Policy podcast. You can also read a policy briefing, Maths Matters, which I devised in 2013 to try to explain the value of maths research to policy makers.
Physics World   My feature article entitled "The geometry of our world" has appeared in the April 2017 edition of Physics World, which you can access by going to physicsworld.com. You can also download the article by visiting my publications page.
Adventures in the 7th Dimension   I spoke in the popular Lunch Hour Lectures for the general public at UCL on 2 March 2017, and the talk is now available to view on the YouTube channel. I was also one of the invited speakers at this year's British Science Festival in Swansea talking about the 7th dimension on 6 September 2016. I was interviewed about my talk on Science Cafe on BBC Radio Wales. I gave a related talk as part of the LMS Popular Lectures in London on 28 June 2017 and in Birmingham on 20 September 2017, and at the Fields Institute (Toronto) on 21 August 2017.
Leverhulme   I have been awarded a Leverhulme Research Project grant with my colleague Felix Schulze at UCL. We had a postdoc (Ben Lambert) and PhD student Chris Evans funded by this grant.
UK-Japan Winter School   I co-organised the 18th UK-Japan Winter School in Mathematics on Singularities, Symmetries and Submanifolds on 4-7 January 2017 at UCL, which was partially funded by the LMS. This brought together researchers in symplectic geometry, mirror symmetry, calibrated submanifolds and geometric analysis. There were three minicourses suitable for graduate students as well as poster sessions for PhD students and research talks. The minicourse speakers were Dominic Joyce, Ailsa Keating and Kazushi Ueda and research speakers included Simon Donaldson and Kauru Ono.
Unwrapping our Modern World  I ran this workshop with artist Lilah Fowler as part of a Maths Arts and Crafts Day for teachers on 25 June 2016 at UCL. In this interactive event, we gave a fresh perspective on the modern world by "unwrapping" through ideas from art and mathematics. We explored a wide range of topics from the mundane like cardboard boxes and maps, to the internet, bitcoin, the shape of the universe and DNA. This built on a previous workshop for the general public.
Take your brain to another dimension   I was delighted to take part in the inaugural MAPS PhesDival at UCL, celebrating research in Maths and Physical Sciences, on 15 June 2016. I took the opportunity to explain my research with a few jokes and some dance moves!
Geometric Analysis Reading Seminar   I am co-organising an informal seminar for geometers and analysts, where we discuss and learn about various topics in Geometric Analysis. Information is available on the seminar website.
Research summaryWhat I do   I work on differential geometry, particularly geometry related with special holonomy and calibrated submanifolds, geometric flows including Lagrangian mean curvature flow and the G2-Laplacian flow, as well as instantons. For further details, and if you are interested in pursuing PhD studies with me, see my research page.
Why anyone cares   The geometries I study are important from the viewpoint of Einstein metrics and gauge theory, and are related to minimal submanifolds and algebraic geometry. In this setting, there are striking interactions expected between the ambient manifold geometry and topology, the calibrated submanifold geometry and instantons. Moreover, the objects I investigate are of potential importance in high-energy theoretical physics.
Current group   Postdoc: Guillem Cazassus. PhD Students: Izar Alonso Lorenzo, Benjamin Aslan, George Cooper, Francesco Di Giovanni, Chris Evans, Hector Papoulias, Daniel Platt and Federico Trinca.
