Abstract
The interdisciplinary nature of bioaerosol study demonstrates both the complexity and importance that this class of aerosols have with our environment and health. Even defining the scope of bioaerosol research is challenging due to its multifaceted nature, spanning diverse motivations and communities. Airborne bacteria, spores, and pollen exert far-reaching influence on natural ecological systems, climate change, and the hydrological cycle. From combating infectious diseases and biowarfare threats to managing seasonal allergies and agricultural crop health, bioaerosols impact nearly all sectors of society and human health. Yet, deeper understanding continues to be challenged, in part, by disconnects between diverse researcher communities and the disparity between scientific questions that drive investigations.

Over the past quarter-century, notable surges of interest have pushed bioaerosol science forward and often into the forefront of the public’s awareness of scientific research. Each surge has also helped foster new connections between ideas and scientists, introduced new techniques, and amplified both opportunities and challenges within the field. Throughout that arc, the American Association of Aerosol Research (AAAR) has been pivotal in advancing bioaerosol science by offering perspectives from deep expertise in the intertwined disciplines necessary to sufficiently understand aerosols. The COVID-19 pandemic has further underscored the complexity of aerosol dynamics and their critical role in disease transmission and public health. Over the last three years, countless AAAR members have worked tirelessly to play crucial roles in driving transformative science, advocating for scientific understanding, and educating the public.

The timing seems opportune to pause and reflect on some of the historical context for the growth in bioaerosol research and recent advancements, both within AAAR and more broadly. While the invitation to address this broad topic is daunting, the talk aims to shine a light on victories and advances of bioaerosol research and to pull in anecdotes from still more experienced researchers for illustration. The goal is to provide both perspective for the contributions AAAR and its members have made to this critical sector of scientific and societal progress and to inspire younger scientists to embrace the non-linear, but interconnected path of aerosol research.
