I grew up in California and received a BS in Chemistry from Brown University where I did research on both water quality and paleoclimate. I did my graduate work with Ron Cohen in the UC Berkeley College of Chemistry where I focused on photochemical ozone production and reactive nitrogen cycling. After receiving my PhD, I became a research scientist at the National Oceanic and Atmospheric Administration in Boulder, CO studying several kinds of atmospheric aerosol. I spent 9 years there doing a variety of airborne, ground-based and laboratory work on black carbon and biological aerosol before joining the Chemistry Department at 新澳彩开奖结果.
In my current research, my students and I use a variety of tools to study primary biological aerosol (bacteria, fungal spores and pollen) which can impact cloud formation and the hydrological cycle as well as human, animal and plant health. We also have a continuing collaboration with NOAA to measure black carbon aerosol from airborne platforms to better understand its sources, chemical transformations and radiative impacts in the atmosphere.
If you would like to learn more, please see sections below on research and publications.

1. Primary Biological Aerosol
To study primary biological aerosol (PBA), composed of bacteria, fungal spores and pollen, we use a number of tools. First, we have a Micro-Orifice Uniform Deposition Impactor (MOUDI) which collects size-resolved aerosol from 50 nm to 18 渭m. We install the instrument in an outdoor location to collect atmospheric samples which we analyze for deposition-mode ice nuclei as well as biomarkers like amino acids and fungal alcohols. We also have a real-time single particle fluorescence instrument (the Instascope) which provides high time resolution data and helps us put our offline measurements into context. We are interested in seasonal cycles of biological aerosol, the behavior and composition of biological aerosol and ecosystem response to meteorological and climatic events.

The MOUDI has 11 stages, each of which is an impactor with a sharp cut-point for a particular size of particles.
The instascope provides real-time, single particle fluorescence measurements for atmospheric aerosol.
2. Black Carbon
Black carbon (colloquially referred to as "soot") is an absorbing aerosol species with impacts on climate and health. Our work with black carbon is an ongoing collaboration with colleagues at NOAA in Boulder who own and operate a Single Particle Soot Photometer (SP2) on various multi-agency airborne projects focused on air quality and climate. We have been involved in several recent missions. During the summer of 2019 we helped with the mission in Boise, Idaho which focused on emissions of particles and gasses from fires. During the summer of 2022 we helped with the mission, based out of Osan AFB in South Korea, which focused on transport of pollution from the surface through convective systems associated with the Asian Summer Monsoon. Most recently, during the summer of 2023, we participated in the mission focused on urban air quality in North American cities.
