Welcome message from the Congress Chair

Dear Colleagues,

Our original plans for WATOC 2020 were derailed by the COVID-19 pandemic.  Assuming that science will triumph over the coronavirus in time, we are now planning to hold the congress in 2022.  On behalf of the Organizing Committee of WATOC 2020, it is my pleasure to request that you reserve the week of July 3, 2022 for the 12th Triennial Congress of the World Association of Theoretical and Computational Chemists ( in Vancouver, Canada. 

The first WATOC Congress in 1987 attracted about 475 scientists to Budapest. More than 1500 registered for the eleventh Congress in 2017 in Munich. In the span of three decades, the triennial WATOC congresses have become an important international gathering of computational and theoretical chemists.

The WATOC 2020 program will feature 12 plenary lectures, 252 invited lectures, 180 invited communications and a large number of poster presentations. The program will cover a broad range of topics in method development and applications to chemistry, biochemistry, materials and nanoscience.

Be sure to check periodically our website ( for more information, as it becomes available. We look forward to welcoming you to Vancouver, Canada’s Pacific gateway, in July 2022.

With best wishes,
Russell J. Boyd
Congress Chair
