SIAM PNW Section

Welcome to the Pacific Northwest Section of the Society for Industrial and Applied Mathematics (SIAMPNWS)!

SIAMPNWS aims to bring together the different communities of the Pacific Northwest that are active in industrial and applied mathematics. Its goals are to enhance communication among its members, to promote collaboration for both basic research and applications of mathematics to industry and science, and to support the SIAM mission in the Pacific Northwest region of the US and Canada.

SIAMPNWS serves the Pacific Northwest region of the USA and Canada, defined here to comprise the states of Idaho, Oregon and Washington, and the province of British Columbia.
