- Lucia Geometrica, 9-13 December 2019. Stockholm University, Sweden. A celebration of geometry: from algebraic geometry to algebraic combinatorics.
- Lattice polytopes, with a view towards Geometry and Applications, 18-20 September 2019. ICMS, Edinburgh. A workshop focusing on the combinatorics of lattice polytopes, with a view towards connection to algebraic geometry via toric geometry, and to applications.
- Mutations: Mirror Symmetry, Deformations, and Combinatorics, 11-16 August 2019. BIRS, Canada. A workshop drawing together world-leading experts from many areas of pure mathematics who might not otherwise interact. The common theme is the presence of mutations in our work, with the focus on overlaps with Mirror Symmetry, deformation theory, and combinatorics.
- Cluster Algebras and Algebraic Geometry,11-14 July 2018. University of Nottingham. A workshop exploring some of the connections between cluster algebras and algebraic geometry. Organised by my then postdoc student Andrea Petracci.
- Interactions with Lattice Polytopes, 14-16 September 2017. Otto-von-Guericke-Universität Magdeburg, Magdeburg, Germany. A workshop on lattice polytopes and their interactions with toric geometry, mirror symmetry, integer optimisation, commutative algebra, etc.
- Experimental Classification of Fano Varieties, 16-18 August 2017. Universität Tübingen. A small workshop on the various methods of computational and experimental classification of Fano varieties, with a focus on Mirror Symmetry and complexity one torus actions.
- 3CinG Workshop on Computational Algebra, 18-21 April 2017. King's College, Cambridge. A workshop to discuss current and future applications of computational algebra in mathematics, with a particular focus on geometry.
- Mirror Symmetry and Pencils of Calabi-Yau Motives, 14-15 February 2015. Huxley Building, Imperial College London. A workshop to discuss recent progress in mirror symmetry for higher-dimensional Fano manifolds, the construction of pencils of Calabi-Yau motives, and connections with arithmetic geometry and the theory of differential equations.
- Magma workshop on Computational Algebraic Geometry, 8-10 September 2010. School of Mathematics, Loughborough University. A practical workshop to discuss possibilities for extending facilities in Algebraic Geometry in existing computational algebra systems such as Magma.

- GAeL XIV, 6-11 March 2006. Stephan Banach Centre, Bedlewo, Poland. With principal talks from Frederic Campana (Nancy), Brendan Hassett (Rice), and Claire Voisin (Paris VI).

- Whilst at UNB I helped organise several geometry seminars. I was also the UNB organiser for the summer 2007 ASCI seminar series.
- Between October 2003 and October 2005 I organised the Calf (junior COW). For information on current Calf events, please go here. For a historical record of the events I organised, go here.
