CV

Catherine Stauffer

Catherine Stauffer is a Postdoctoral Researcher.  Her work involves quantifying Arctic surface cloud feedbacks and decomposing the feedbacks into cloud microphysical contributions using a combination of remote sensing and radiative transfer modeling.  She earned her Ph.D. in Meteorology from Florida State University in 2023 on tropical cloud changes and feedbacks using idealized modeling.  For fun she likes to exercise and explore the outdoors.

Calvin Coulbury

Calvin Coulbury is currently a Ph. D. student researching Arctic cloud feedbacks using global climate models and remote sensing observations.  He earned his B.Sc. in Physics and Atmospheric and Oceanic Sciences at McGill University in May 2022.  Prior to that, he analyzed radiative feedbacks in contemporary climate models for his ATOC 396 Undergraduate Research Project and his McGill SURA internship in Summer 2021.  His hobbies include board games, going to the gym, and playing ultimate frisbee.


CV

Aubert Lamy

Aubert Lamy is a Ph.D. student analyzing the relationship between clouds and climate sensitivity in contemporary global climate models.  He earned his B. Sc. in Physics at The Université du Québec à Trois-Rivières in 2023.  He is continuing the research project he conducted for his NSERC SURA internship in Summer 2022.  Outside of work, he enjoys playing chess, guitar and outdoor activities.


CV

Mees Franssen

Mees Franssen is a Ph.D. student researching and modelling Arctic aerosol-cloud interactions.  He earned his B.Sc. at McGill University in December 2023 with a major in Atmospheric and Oceanic Sciences and a minor in Environmental Science.  During his time at McGill University, he completed a number of funded summer research internships where he gained most of his research experience.  His hobbies include running/hiking, climbing and playing the guitar.

Cameron Toy Kluger

Cameron is an undergraduate student at McGill University in the Honours Environment program under the Faculty of Science.  For his ATOC 396 Undergraduate Research Project in Summer 2023, he is investigating differences between eastern and western cloud formations in the Antarctic in CMIP models. In his free time, he can be found hanging out with his pets, hiking, and playing basketball.

Past group members

Quentin Coopman

Quentin Coopman was a Postdoctoral researcher in the remote sensing group lead by Ivy Tan in the Department of Atmospheric & Oceanic Sciences at McGill University from February 2021 to August 2023. Quentin’s work focuses on mixed-phase clouds in the Arctic using observations.  He is currently an Assistant Professor at the University of Lille.  Before coming to McGill, Quentin was at the Karlsruhe Institute of Technology as a Postdoctoral researcher in cloud Physics, developing a cloud tracking algorithm from space-based observations to analyse the cloud thermodynamic phase transition. Before that, Quentin did his PhD in Atmospheric Science at the University of Utah (USA) and the University of Lille (France) on the aerosol-cloud interaction in the Arctic. Outside of work Quentin enjoys reading, running, playing video games, and saxophone.
