Dr. Andreas (Andi) Zuend, Associate Professor in the Department of Atmospheric and Oceanic Sciences.
He obtained his PhD from the Swiss Federal Institute of Technology Zurich (ETH Zurich), Switzerland, for his thesis conducted in the Atmospheric Chemistry group of Prof. Thomas Peter. His postdoctoral research was carried out at the California Institute of Technology (Caltech) in the group of Prof. John H. Seinfeld and at ETH Zurich.

Camilo Serrano Damha, PhD student in Prof. Zuend's group since 2019.
Camilo earned a BSc in Chemistry from McGill University where he was an intern in the Synthetic Organic Chemistry research group of Dr. Moitessier. He later obtained a BSc in Atmospheric Sciences from UQAM where he worked in the Climatology research group of Dr. Gachon. During his undergraduate studies, he developed a keen interest in atmospheric chemistry and physics. He joint our group in 2018, initially as a MSc student. His current research project involves improving the parameterization of physicochemical processes related to organic aerosols such as gas–particle partitioning and liquid–liquid phase separation in large-scale simulations of the atmosphere through incorporation of thermodynamic models into global and regional 3-D chemical transport models.

Ryan Schmedding, PhD student in Prof. Zuend's group since 2020.
Ryan earned a BSPH in Environmental Health Science with Minors in Chemistry and Biology from the University of North Carolina at Chapel Hill in 2018. He went on to earn his MSc in Environmental Science and Engineering at UNC-Chapel Hill working with Prof. William Vizuete on research focused on modelling air pollution over North America. His current areas of research interest is on understanding the physical and chemical properties of aerosols and how they lead to the activation of cloud condensation nuclei.

Zixuan Shen, PhD student in Prof. Zuend's group since fall 2021.
Zixuan graduated in 2021 with a Bachelor of Science degree in Atmospheric Science from Nanjing University of Information Science & Technology, where she was selected as an outstanding valedictorian. Her previous research was focused on optical hygroscopic particle growth parameters and aerosol characteristics in different regions. Zixuan's undergraduate thesis focused on the hygroscopicity of atmospheric aerosols based on a chemical component parameterization. Her current research interests involve atmospheric chemistry and coupled kinetic–thermodynamic modeling of indoor and outdoor aerosol processes.

Dan Hassan-Barthaux, PhD student in Prof. Zuend's group since 2023.
Dan earned his MSc degree in the Department of Atmospheric and Oceanic Sciences at McGill (2021–2023). His MSc research focused on the interplay of particle composition, size, surface properties and variability in environmental conditions on aerosols and cloud droplets. Prior to his time at McGill, Dan obtained a Bachelor of Science degree in Meteorology and Climate from the University of Reading in the UK. His first exposure to meteorology was working with a mobile radiosonde launch site, which inspired his further studies in this discipline. In his PhD research, Dan is interested in the formation and evolution of aerosols influenced by wildfire emissions and their impact on air quality and clouds.

Ben Bergen, MSc student in Prof. Zuend's group since fall 2022.
Ben earned a BSc in Chemistry and Physics from Carleton University in 2022. He became interested in atmospheric science during a co-op term with Environment and Climate Change Canada where he worked as a data analyst for the National Air Pollution Surveillance Program. Ben’s research will involve modeling studies on the influence of organic compounds, such as organosulfates, on aerosol acidity and multiphase processes.

Dalrin Ampritta Amaladhasan, (former) PhD student in Prof. Zuend's group; now at BASF.
Ampritta's research involved the development of software tools for the automated classification of organic aerosol compounds' functional groups using cheminformatics API and incorporating it in structure–property predictive models, such as the AIOMFAC model. Her research focused on improving simulations of gas–particle partitioning of aerosol components using state-of-the-art chemical mechanisms with group contribution methods for vapor pressure estimation and particle-phase thermodynamics in a box model.
