Welcome to the ASE Laboratory!

The broad theme of our work is to understand key processes that drive the properties, distribution, and evolution of aerosols (also known as particulate matter), and to elucidate and quantify the effects of aerosols on air quality, biogeochemical cycle, hydrological cycle, and climate. The overall goal is to obtain a predictive understanding of aerosol properties, processes, and effects to address the grand challenge of actionable projection of future climate and environment.

Our research consists of development of cutting-edge sensors and instruments, field observation using these advanced sensors and instruments, and analyses of data making use of a variety of theoretical and numerical models.



The Atmospheric Science and Engineering group is looking for two postdocs to join our team. The research topics are (1) the development of novel instruments for rapid measurements of aerosol size spectrum, hygroscopic growth, and mixing state onboard manned and unmanned aircraft, and (2) the processes that drive the aerosol hygroscopicity and cloud condensation nuclei spectrum, and the interactions between aerosol and clouds. The description of the positions is available here.

We are also seeking enthusiastic and talented students to join our team. At present, undergraduate research assistant, independent study, and Ph.D. student positions are available.

I welcome the opportunity to talk with you about our research and your interest in joining our team. Please feel free to contact me with any questions you might have at jian@wustl.edu.
