Esteben Avella Shaw 

In Fall 2022, I began my Master's journey at McGill. Prior to this, I graduated from the B.Sc. Soil, Water, and Atmosphere at Wageningen University and Research in the Netherlands. During the third year of my undergraduate studies, I had the opportunity to participate in an exchange program at NMBU in Norway. It was in Norway that I developed a profound passion for cold climate phenomena. This fervor ultimately led me to join the sea ice group in the AOS department at McGill. I am currently under the supervision of Prof. Carolina Dufour, working on the impact of topography and mesoscale eddies on ocean heat transport from the Atlantic to the Arctic. And just for a light-hearted aside: if you ever come across Dutch rap on streaming platforms, you might just hear my voice!

Aditya Baksi

I joined as a PhDstudent at the Department of Atmospheric and Oceanic Sciences at McGill University and my research is supervised by Dr. Peter Bartello. I completed my bachelor’s degree in Mechanical Engineering from National Institute of Technology, Surat, India. I became fond of Fluid dynamics which led me to my master’s degree in Climate Science from Indian Institute of Science, Bangalore. My thesis was about the non-linear adjustment in the tropics, in which I studied the evolution of the shallow water equations in spherical geometry. Currently, my broad area of interest is Geophysical

Florence Beaudry

Before coming to McGill, I earned a BSc in Chemistry and Physics from Carleton University. I became interested in atmospheric science during a co-op term with Environment and Climate Change Canada where I worked as a data analyst for the National Air Pollution Surveillance Program. Outside of school I enjoy reading, playing volleyball and solving Rubik’s Cubes competitively.

Stephanie Bergeron

I began my master in the AOS department at McGill in the fall of 2022. Prior to this, I completed my undergraduate studies at UQAM in Earth and Atmospheric sciences. I also had the opportunity to do research internships at UQAM and Ouranos mainly on winter precipitations. One of my most recent professional experiences is to do science popularization as a video-meteorologist at MétéoMédia. My master’s thesis will be supervised by Prof. Bruno Tremblay and Simon Bélanger, professor at UCAR. I will focus on understanding the biophysical processes trigger by sea ice lost in the Arctic and their impacts on phytoplankton production, more precisely in the Tallurutiup Imanga region. Other than my academic interests, I am probably the biggest Céline Dion fan you know and I never back down from a good karaoke night.

Angela Cheng

I am a Ph.D. candidate under the supervision of Dr. Bruno Tremblay. My research is in partnership with the Canadian Ice Service, which is part of the Meteorological Service of Canada under Environment and Climate Change Canada. I work in the Applied Science group. I am also co-supervised by Dr. Barbara Casati, (Meteorological Research Division of Environment and Climate Change Canada), and Dr. Adrienne Tivy (Canadian Ice Service, Environment and Climate Change Canada).
I received my MSc. from Queen's University in 2015 and a Bachelor of Environmental Studies from the University of Waterloo in 2008. I also have a Diploma of Excellence in Geographic Information Systems from the University of Waterloo, 2008.

If a weather model correctly forecasts a thunderstorm, but gets the location wrong, then is it still considered accurate? What if a second weather model forecasts clear skies instead of the same thunderstorm? Is that model more or less accurate than the first? Arguably the first one is more accurate because it got the initial processes right—that is, unless you're at the thunderstorm's location without an umbrella. Then they're equally wrong. Now replace thunderstorm with sea ice, and that is the focus of my research.

Current verification metrics for measuring the accuracy of forecasts don't always measure the performance of these models spatially in a meaningful way. My research focuses on spatial verification and spatial metrics for sea ice models. From a broad perspective, I am interested in how we can assess the accuracy of spatial data. With specific application to sea ice, I am researching how we can compare sea ice forecasts against observations from a spatial perspective. I want to make new rulers that don't exist to measure in space and time.

My research projects include: 1. Assessing sea ice concentration estimates in sea ice charts. 2. Using spatial techniques to assess the accuracy of forecasted sea ice pressure in numerical models. 3. Investigating and developing new spatial verification techniques, with specific application to sea ice models.

University and MSc in atmospheric sciences from National Taiwan University. I was then working on convective aggregation development with a cloud-resolving model.
