August 2015: Tudur is at the Welsh National Eisteddfod with bubble demonstrations and other mathematical treats.

July 2015: We have been awarded a grant by EPSRC to work on the Flow of Gas-Liquid Foams in Narrow Complex Geometries. This is a joint project with colleagues in Birmingham and Cambridge, with industrial support from BTG, Unilever and Schlumberger.

June 2015: Simon will give an introduction at the prize giving ceremony for the Maths Challenge organised by the University's widening participation team. The questions were on a theme of Alice in Wonderland, celebrating the 150th anniversary of the publication of Lewis Carroll's book.

May 2015: Simon and Tudur attended the LMS WIMCS – Bath Analysis Day, including a special guest lecture from Neil Sloane, founder of the Online Encyclopedia of Integer Sequences.

March 2015: Simon will give a public lecture on foams at Lincoln University on Monday 2nd March.

January 2015: Last chance to submit abstracts for the next spring meeting of the Institute of non-Newtonian Fluid Mechanics at Ruthin Castle, 30th March to 1st April 2015. The theme will be Structured Fluids. See the INNFM website for further details.

December 2014: Simon attended the British Society of Rheology's midwinter meeting on active and complex fluids at Durham.

September 2014: This month's science cafe at Aberystwyth Arts Centre was on Mathematics in the Bath. Simon presented some ideas from the geometry of soap bubbles, followed by a grilling from the audience.

August 2014: Simon was interviewed on Radio Cardiff as part of the Science and Technology Radio Show "Pythagoras' Trousers", talking about foams and bubbles.

July 2014: Michael Dennin from UC Irvine is visiting Aberystwyth to discuss foam rheology.

July 2014: Simon attended the EuFoam conference in Thessaloniki, Greece, speaking about The effects of channel geometry on foam structure and flow, and a conference on Recent Advances in Numerical Simulation of Hydraulic Fracture in Rzeszow, Poland, speaking about The effects of pore geometry on foam flow in porous media.

June 2014: Tudur and Llinos got married!

May 2014: Simon is currently on overseas leave as Professeur Invité at the Laboratoire Matière et Systèmes Complexes at the Université Paris Diderot for a month, working with Florence Elias and others.

April 2014: The next spring meeting of the Institute of non-Newtonian Fluid Mechanics will be at Ruthin Castle, 30th March to 1st April 2015. The theme will be Structured Fluids. See the INNFM website for further details.

April 2014: From 14th to 16th, Tudur and Simon are at the Institute of non-Newtonian Fluid Mechanics Spring Meeting at spectacular Lake Vyrnwy. The theme of this year's conference is Advances in Rheometry, and the proceedings will be dedicated to Ken Walters on the occasion of his 80th birthday and in recognition of his contributions to rheology. The meeting also plays host to the AGM of the British Society of Rheology.
