The research of the Jimenez group centers on the development and application of advanced instrumentation for real-time, quantitative measurements of the size, chemical composition, and morphology of submicron aerosols. We care about atmospheric aerosols for many reasons, including their effect on radiation balance (climate forcing), severe short-term and long-term effects on human health, reduced visibility, and deposition of acids, toxics, and nutrients to ecosystems and crops. Most of these effects are not well understood, in good part due to the limitations of the instrumentation available. Advanced instrumentation can be used to make much faster progress in many of these areas. Since the COVID-19 pandemic we are also doing research on airborne disease transmission.
CHEM 5152 - Advanced Atmospheric Chemistry
Spring 2019 / Spring 2020 / Spring 2021
Follows Graduate Atmospheric Chemistry (CHEM 5151) and explores advanced topics in atmospheric chemistry, such as secondary aerosol formation, oxidant formation, the chemistry of global climate change and/or design of advanced laboratory experiments. Recommended prerequisite: CHEM 5151 or ATOC 5151. Same as ATOC 5152.
CHEM 5181 - Mass Spectrometry and Chromatography
Fall 2018 / Fall 2019 / Fall 2021
Covers mass spectrometry, including instrumentation, ionization techniques, and interpretation of spectra. Analytical separation methods such as gas and liquid chromatography, ion mobility, and capillary electrophoresis. Introduction to atmospheric chemistry applications. Computer programming (Igor and LabVIEW) and simulation of instrumentation and processes. Department prerequisite: basic computer programming (or willingness to work hard on it), and undergraduate physics, statistics, and physical chemistry.
