Women in Aerosols

Aerosol Devices Inc. Founded in 2014

Aerosol Devices Inc. was founded in 2014 in Fort Collins, Colorado by two professional women in aerosols.  Our primary goal is to bring to market advanced aerosol collector technology developed by Dr. Susanne Hering and her creative team of scientists at Aerosol Dynamics Inc. (Berkeley, CA). Over the past five years, research prototypes were developed to collect uninterrupted, time-resolved, concentrated samples of ambient aerosol particles in the field for chemical analysis in the lab. Recently a collection module has been developed to efficiently deposit particles into liquid forming concentrated particle suspensions. Variations of the collector prototypes are used in creating colloidal particle concentration standards, studying combustion soot particles, purifying protein samples, and much more.

A grant from the National Institutes of Health (1 RC3 ES019081-01) funded the collector development.  Please check out the Reference section to read more about the early development, performance, and field sampling results.

Both of the company’s founders, Ms. Pat Keady and Dr. Susanne Hering, are past Presidents of the American Association for Aerosol Research (AAAR) and leaders in the field with numerous aerosol measurement patents and publications.  With a strong business and engineering background, Ms. Keady serves as the company CEO/President.  Dr. Hering contributes as a technical adviser to the company while continuing her role as President of Aerosol Dynamics Inc., a very successful and well-respected R&D firm.

Our Founders

Pat Keady

Pat Keady


Pat has extensive business experience in the aerosol instrumentation industry within division and corporate-level management of engineering, sales and marketing, quality, human resources, and manufacturing. She is a past President of the American Association for Aerosol Research. Pat received her MS Mechanical Engineering from the University of Minnesota and MBA course-work from the University of St. Thomas, St. Paul, MN. She holds two patents for aerosol instrumentation.

Dr. Susanne Hering

Susanne Hering

Founder/Scientific Advisor

Susanne is Founder and President of an R&D company, Aerosol Dynamics Inc. (Berkeley, CA), that develops innovative aerosol measurement instrumentation and runs field testing campaigns supported primarily through Federal Government SBIR grants.

She has served as a President of the American Association for Aerosol Research, and in 2007 was honored as the recipient of the BYH Liu Award, presented by the Association in recognition of contributions to aerosol instrumentation. Currently she is an Editor for Aerosol Science & Technology. Susanne received her PhD in Physics from the University of Washington, with postdoctoral work in Environmental Engineering at the California Institute of Technology. Susanne has over 100 technical publications and holds 18 patents (issued and pending) related to aerosol measurement technologies.
