On behalf of the conference organizers, it is my great pleasure to invite you to the 10th International Aerosol Conference (IAC 2018) to be held September 2-7, 2018 at the America’s Center in St. Louis, Missouri, USA. As you may know the IAC is held once in four years, and rotates between Asia, Europe and America – hence we will be hosting this in the USA after 12 years. The IAC attracts attendees from all over the world. We expect the conference to provide an outstanding venue for sharing our latest aerosol science and technology research and for networking and re-connecting with colleagues.

　　The 2018 IAC provides one more day of scientific sessions than our regular AAAR conferences:

　　The regular full slate of tutorials on Sunday on a wide range of aerosol science topics, including the popular "Hands-on Aerosol Instrumentation Design and Measurement" tutorial.

　　An exciting array of plenary talks, special symposia, poster sessions, platform presentations, and special events from Monday morning through Friday.

　　Nine different Symposia on topics ranging from Low Cost PM Sensors to Infectious Aerosols to Reactor Studies to Mega Cities are being planned.

　　The Conference Committee’s Technical Program co-chairs Drs. C.Y. Wu (University of Florida) and Brent Williams (Washington University in St. Louis) are diligently working to develop the program.

　　Please note that the Call for Abstracts is now open (aaarabstracts.com/2018IAC/) and that the deadline for submissions is February 1, 2018.

　　This year we will have some additional highlights:

　　A Workshop that will discuss and identify the scientific challenges in the field of aerosol science and engineering.

　　An opportunity to submit a picture of your best looking or most interesting particles, and win prizes!

　　Meet the Pioneers, where you can interact with leaders in the field in an informal setting.

　　Technical tours to local universities, start up incubator parks, and local industry.

　　Recreational tours – opportunities for your entire family to enjoy (so ask them to come along too!).

　　A Banquet, which will be a great opportunity to celebrate and mingle with colleagues.

　　And much more!
