Letter from the Conference Chair

Dear Colleagues,

Preparations are moving swiftly along for the 41st Annual AAAR Conference, to be held from October 2-6, 2023 at the Oregon Convention Center in Portland, OR. I know I speak for many when I say I’m so excited to be heading back to beautiful Portland to reconnect with the dynamic and welcoming AAAR community!

Abstract Submissions have now closed and we look forward to reviewing your submissions over the next few weeks!

As a reminder, the 2023 Conference will feature four exciting and discipline-crossing Special Symposia that I hope you will consider submitting to:

  • Identifying and Addressing Disparate Impacts of Aerosol Exposure: Marginalized to Mainstream, Outdoors to Indoors, Global North to South
  • Aerosol Science of Infectious Diseases: Lessons and Open Questions on Models, Transmission and Mitigation
  • Aerosols Spanning Spatial Scales: Measurement Networks to Models and Satellites
  • Aerosols and Ecosystem Health

More information on these can be found at

Tuesday, Wednesday, and Thursday morning will all start with an 8am Plenary Lecture, while (following on the success of a new schedule last year) we will have the Friday Plenary Lecture close the Conference. Our outstanding lineup of Speakers includes Julian Marshall (University of Washington), Nicole Riemer (University of Illinois), Lidia Morawska (Queensland University of Technology) and Vanderlei Martins (University of Maryland, Baltimore County)

An exciting new addition for the 2023 AAAR Conference is an ‘Exhibitor and Instrument Application Showcase’ area and platform track to encourage interaction between exhibitors and other attendees and to provide opportunities for practical education and exchange focusing on real measurement applications and challenges. Please consider submitting for this session!

More information on this new session can be found at

Finally, we are preparing a range of special events to accompany the technical program. One to highlight is that we are excited that we will have a reprise of the popular Monday evening Science Communication program, this year featuring veteran science communicator Andrew Revkin as a featured speaker! Andrew will also be leading a tutorial on Science Communication.

Speaking of tutorials, the community is hard at work assembling a terrific and diverse array of tutorials, including our Hands-On Aerosol Instrumentation Design and Measurement Tutorial. There are also plans afoot to offer our first ever ‘off-site’ tutorial, offered on the campus of Portland State University – please keep your eyes peeled for these exciting opportunities when registration opens in June!

This year we will again have both Student Poster and Platform Competitions. Students don’t forget to sign up when you submit your abstract! We will be looking for judging volunteers when registration opens up as well!

We also invite abstracts again this year for the Meet the Job Seekers Poster Session. This is for Job Seekers to present their background and expertise to potential employers across academia, government, and industry; also for potential Employers to meet the Job Seekers. To submit an abstract for this Poster Session, please follow the directions provided at

As in previous years, a limited number of 3 different types of Travel Grants will be available:

  • Students Studying in the U.S.
  • Students Studying in the Americas Outside of the U.S.
  • International Professionals in the Americas Outside of the U.S.

We are also planning for Student Assistants and Social Media Ambassadors. The Calls for Travel Grant, Student Assistant, and Social Media Ambassador Applications are anticipated to open in May following the abstract submission deadline.

The Technical Program and Conference Committees are also planning for a number of events and programs to be offered during the Conference including:

  • 18 Tutorials on diverse topics related to aerosol science and technology
  • Monday Evening Program and Activities following the Tutorials
  • Early Career Event
  • Representation and Equity Affairs Program
  • Fine Particle Art and Video Competition

We are working on building the Conference website, so please plan to check back often, as we will continuously update in the coming months.
Lastly, if you have any questions about abstract submission reach out to or AAAR Membership details reach out to And of course, please feel free to reach out to me at with questions, ideas or concerns!
