Eyad Attallah

I am a life-long weather enthusiast with a varied background including operational forecasting, television, as well as academia. I specialize in the synoptic analysis of extreme weather events and climate change with over 30 peer reviewed publications on extra-tropical transition, extreme precipitation events, droughts in western North America, and the impacts of climate change on temperature regimes over North America. I have also instructed several classes ranging from large introductory survey classes to specialized graduate classes in topics including climate change, operational forecasting, as well as synoptic and mesoscale dynamics. In 2015 I was awarded the McGill Principal’s Prize for excellence in teaching in the category of faculty lecturer and was selected as the Canadian Meteorological and Oceanographic Society’s tour speaker in 2013. In the winter of 2011-2012, I led an outreach mission to aboriginal communities in northern Canada, consulting with community elders and students as to the expected outcomes of climate change and helped lead discussions on adaptation and mitigation strategies. Finally, I am an intermittent tornado-chaser and have gone on approximately 10 tornado chases, including leading two storm-chasing field courses here at McGill.

Sisi Chen

I recently finished my Ph.D. in department of Atmospheric and Oceanic Sciences at McGill University. I am currently a postdoc researcher working with Prof. M.K. (Peter) Yau.

My current research interests are the aerosol impact on the development of clouds and precipitations in turbulent environment, the aerosol-cloud interaction, and the feedback of multiscale dynamics (both small-scale turbulence and large-eddy hopping) on the cloud microphysics (such as the evolution of droplet size distribution, autoconversion process, etc).

My Ph.D. project deals with rain formation in warm, shallow convective clouds. In particular, I am looking at how small-scale turbulence affects the droplet growth. I am using direct numerical simulation (DNS) to simulate the process happening inside the cloud adiabatic core region. By tracing the Lagrangian trajectory of each droplet inside the cloud, we can monitor the growth history of every droplet, in the hope of quantifying the turbulence impact on raindrop formation.

My supervisor was professor Yau. I then became a post-doctoral fellow at the department working with Dr. David Schecter and Dr. M. K. Yau. In 2017, from April to June, I worked as NSERC Visiting Fellow in Canadian Government Laboratories at Environment and Climate Change Canada (Dorval).

Kyle Gorkowski

I joined McGill as a  postdoctoral researcher with Dr. Zuend and Dr. Preston in October 2017.

I conducted my Ph.D. work,  in Environmental Management and Science, at Carnegie Mellon University (Pittsburgh, Pennsylvania USA) as a part of Dr. Ryan Sullivan’s and Dr. Neil Donahue’s research groups in the Center for Atmospheric Particle Studies. My Ph.D. work focused on the development of experimental methods for the aerosol optical tweezers and new analysis algorithms for Whispering Gallery Modes. The research theme centered around liquid-liquid equilibrium of laboratory generated secondary organic aerosol. 

In Dr. Zuend’s group, I am developing computationally efficient numerical models of atmospheric aerosols. The overarching goal is to make the next generation of aerosol thermodynamic models. In Dr. Preston’s group, I am working on aerosol viscosity and surface tension measurements using the aerosol optical tweezers. There is a large data gap in understanding under what conditions aerosol particles can transition from a liquid-like particle to a solid-like particle (or the reverse). Determining under what aerosol compositions and conditions this happens is important as it will inform how to include this effect into the next generation of aerosol dynamic models. These models are used in large-scale simulations of the atmosphere to predict regional air pollution and the long-term impacts of climate change.
