International Year of Crystallography - 2014

IYCr logo UNESCO designated 2014 as the International Year of Crystallography. Events were held throughout the year, with the climax at the IUCr's Congress and General Assembly in Montreal, Canada.

Crystallographic organisations

I am currently involved with several different Crystallographic organisations.

BCA logo The principal organisation involved with education and promotion of Crystallography within the British Isles is the British Crystallographic Association. It caters for Crystallography in different fields of science - Biological Structures, Chemical Crystallography, Industrial Crystallography and Physical Crystallography. The interests of Young Crystallographers in all these disciplines are catered for in their own Group.

Next year's Annual BCA Meeting will be held at the University of Nottingham from Monday 4th April - Thursday 7th April 2016

Each of the Groups organises their own meetings in the Autumn and Winter; these meetings address particular issues of current importance and interest.

Membership of the BCA entitles the member to reduced rates of attendance at meetings of both the BCA and of all its Groups; student and post-doctoral members can apply for generous bursaries to help cover the cost of attending relevant meetings both in the UK and abroad.

ECA logo In Europe and Africa, the regional interests of Crystallography come within the purview of the European Crystallographic Association. The ECA organizes a meeting every year in which there is no IUCr Congress.

This year's European Crystallographic Meeting will be held in Rovinj, Croatia from Sunday 23rd - Friday 28th August.

I am currently the Chairman of the ECA's Special Interest Group in Crystallographic Computing - "SIG9" or "ECACOMSIG", and am looking after their web-pages, which have some information about activities and sources of crystallographic software.

ECACOMSIG will be holding a Workshop on Software Development for Crystallographers in Rovinj, Croatia, prior to ECM29, also in Rovinj in August 2015.

News - 24th July 2015

We have been informed that the Hotel Croatia in Duga Uvala (where the School was originally planned) has cancelled all bookings, so the School cannot take place there.

The School will now take place in Rovinj - an alternative venue has been found, and accommodation bookings made through the ECM29 registration process will be transferred.

People who have already registered should see the School web-pages for further details.

IUCr logo The Global umbrella organization for the National and Regional Crystallographic Associations is the International Union of Crystallography, which has operated since 1948. As well as holding a Congress and General Assembly every three years (the next will be in Hyderabad, India, from 21st - 29th August 2017).

The IUCr publishes scientific journals and books on many aspects of Crystallography.

The IUCr's Commission on Crystallographic Computing (of which I am Chairman) is planning to hold a Summer School in Bangalore, India in 2017 before the General Assembly.
