University of Washington
PhD student
My research is on the influence of convection over land on the evolution of tropical tropopause layer cirrus in western Africa. I use high-resolution storm-resolving model data from the DYAMOND intercomparison project.
Sami Turbeville
University of Washington
PhD student
Using the global storm-resolving models from DYAMOND, I am analyzing thin cirrus in the tropical tropopause layer (TTL) and water budget in the tropical western Pacific. The models simulated the month of August 2016, so I can directly compare them with observations from that time period.
Colin Tully
ETH Zürich
PhD student
I study cirrus cloud impacts on climate through aerosol-cloud interactions using the general circulation model ICON-HAM. My research will focus on the sensitivity of cirrus cloud formation to certain natural and anthropogenic forcings, such as aircraft emissions.

Adam Sokol
University of Washington
PhD student
I study the radiative and microphysical evolution of tropical anvil clouds using satellite observations. Anvil clouds play a critical role in the tropical energy balance and are an important source of upper tropospheric ice crystals and water vapor.
David Wei
Harvard University
PhD student
I’m working on two aspects of moist convection modeling: comparing simulations with observations, from which I develop more realistic modeling setups, and designing an accurate convective parameterization based on linear response functions.
Aaron Match
PhD student
I study the global-scale circulation in the tropical stratosphere, particularly the "buffer zone" of the Quasi-Biennial Oscillation.
Katie Kloska
University of Chicago
PhD student
I am interested in atmospheric chemistry and water transport and will be participating in the summer 2020 ACCLIP campaign to measure Asian monsoon outflow and cirrus in the East Pacific.
Andries-Jan de Vries
ETH Zurich
postdoc
In my research project we use the regional COSMOiso model to study the hydrological cycle and its isotopic composition of the West African monsoon. Special focus is on ice cloud formation processes and their isotope signatures.
Rachel Atlas
University of Washington
PhD student
I use aircraft observations and large eddy simulations to understand how dynamical and microphysical processes determine the radiative properties of clouds. I have studied mixed-phase boundary layer clouds over the Southern Ocean and midlatitude cirrus, and I will shift my focus to TTL cirrus in the near future.
Julia Schneider
PhD student
Using the AIDA cloud simulation chamber at KIT, I study the primary ice formation mechanisms at deep convective and TTL cirrus formation conditions experimentally and work in close collaboration with the process modelers from FZ Jülich. In addition, I focus on the experimental determination of the water saturation pressure in the cirrus temperature regime.
Forschungszentrum Jülich
PhD student
I use process models CLaMS-Ice and MAID to investigate the ice nucleation and evolution of cirrus clouds. I have been investigating both evolution of clouds and detailed microphysics of heterogeneous and homogeneous nucleation and their respective parameterizations.
Zeyuan Hu
Harvard University
PhD student
I am working on numerical modeling of cirrus cloud and tropical tropopause layer.
Princeton University
Karlsruhe Institute of Technology
Karlsruhe Institute of Technology
Postdoc
I am interested in the radiative and hydrological effects of tropical convective systems. Currently I am simulating anvil outflow over the Asian monsoon region with the ICON model.
University of Washington
Postdoc
I study upper tropospheric clouds, their lifecycle, and impacts on climate. I am particularly interested in the transition of thick convective anvils into thin cirrus in present and future climate.
Fayçal Lamraoui
Harvard University
Postdoc
My research interests involve cloud and convective processes. I use observations and isotope-enabled cloud-resolving models to study the interaction between dynamical and microphysical properties of deep convective cloud systems, and their representation in numerical models.
Princeton Univerisity
Postdoc
I study how land surface affects behaviors of deep penetrating convection (above the tropical tropopause layer). I also investigate how deep convection changes with global warming and how this leads to changes in cirrus clouds. I employ a hierarchy of models.
Benjamin Clouser
University of Chicago
Postdoc
My research focuses on spectroscopic measurements of water vapor isotopologues to diagnose the influence of deep convection in the tropics.
Maximilien Bolot
Princeton Univeristy
Postdoc
I work on tropical convection, troposphere-to-stratosphere transport, and dehydration in the tropical tropopause layer with a focus on thin cirrus clouds.
Christian Rolf
Forschungszentrum Jülich GmbH
Postdoc
My research focuses on the transport of water vapor in the upper troposphere and lower stratosphere in connection with ice formation and dehydration. I'm doing experimental field work with research aircraft but also work with models like CLaMS/CLaMS-Ice to interpret those measurements.
Manuel Baumgartner
Johannes Gutenberg University Mainz
Postdoc
My research interests include the modeling of clouds, particularly cirrus clouds. Here, I extend and apply the numerical process model CLaMS-Ice, which allows to simulate cirrus clouds and their properties along an atmospheric trajectory. To complement the observations from the AIDA cloud chamber, I use CLaMS-Ice to model the experiments.
