I study the weather-chemistry-climate coupling between the stratosphere and troposphere using satellite observations and global climate models. My work focuses on the large-scale circulations and their impacts on the atmospheric composition, and how variation of trace constituents, in turn, impact the climate and chemistry.

I am currently an Assistant Professor in the Department of Atmospheric and Oceanic Sciences (ATOC), University of Colorado Boulder. Before starting at CU, I was an Advanced Study Program (ASP) Postdoctoral Fellow at the National Center for Atmospheric Research (NCAR). I received my doctorate degree in Earth Sciences in 2020 from the Department of Earth, Atmospheric and Planetary Sciences, Purdue University. 

• EGU 2025 UTLS Session: dynamics and chemistry of the upper troposphere and stratosphere

• The composition of the upper troposphere and stratosphere plays a key role in the climate system. Our understanding of the interactions between dynamics, chemistry and climate in this region is rapidly advancing thanks to both observational and modelling studies. In this session, we invite presentations on dynamical, transport and chemical processes determining the variability and long-term trends in the composition of the UTLS, and related effects on radiation and dynamics.

• The AMS Middle Atmosphere focuses on processes in the stratosphere and mesosphere and their relevance to weather and climate, including:

  • Chemistry of the middle atmosphere, including studies of the ozone layer, its depletion, and its recovery due to the Montreal Protocol and its Amendments;

  • Changes in the middle atmosphere due to human alterations or to natural variability, on decadal to longer timescales;

  • Dynamics of the middle atmosphere, the predictability of dynamic stratospheric events, and their influence on the troposphere;

  • Transport and mixing of chemical constituents in the upper troposphere and stratosphere;

  • Aerosols and influences on radiative processes in the middle atmosphere, including volcanic eruptions and stratospheric geoengineering;

  •  Influence of atmospheric waves on the middle atmosphere

  • Connections between the stratosphere, mesosphere, and upper atmosphere;

  • Feedbacks between tropical convection and stratospheric processes;

  • the Quasi-biennial Oscillation and its teleconnections;

  • the stratospheric polar vortices and influences on mid-latitude weather and climate
