About

Welcome to the Northwest Chapter of the American Association of Physicists in Medicine (NWAAPM)!

We are a community of medical physicists serving the Northwest region, including Washington, Oregon, Idaho, Montana, and Hawaii. Our chapter is dedicated to supporting the professional development of our members and fostering collaboration across the medical physics community.

Each year, we host scientific meetings during which members can present their research, share clinical innovations, earn continuing education credits, and engage in valuable networking with colleagues and vendors from across the region. These meetings also provide a platform for students and trainees to showcase their work and win prizes in the MedPhys SLAM and the Early Career Investigator Symposium.

Thank you for visiting our website. If you’re interested in membership, sponsorship opportunities, or attending one of our events, please don’t hesitate to reach out—we’d love to hear from you!

The NWAAPM is led by an elected team of officers, including the Acting President, President-Elect, Past-President, Secretary, Treasurer, and Chapter Representative to the AAPM Board. Annual elections for officer positions are held each spring, and we welcome you to consider nominating yourself or a colleague for a position on the NWAAPM Executive Committee. It’s a great way to help shape the direction of the chapter and support the broader medical physics community.
