Jérémy Baudry, M.Sc.
Research agent
Université du Québec à Rimouski
Jeremy has a master's degree in physical oceanography. He is interested in modeling waves and hydrodynamic processes in coastal environments. In particular, he is involved in the development of a wave and coastal water level forecasting system in Grise Fiord (Ausuittuq) in order to reduce the risk of hazards during storms. His work focuses in particular on the processes affecting wave propagation in shallow waters as well as wave-ice interactions in the marginal zone. He has also participated in several studies aimed at characterizing the impact of waves generated by ships in confined environments, particularly in Cambridge Bay and the St. Lawrence River.
Antoine Boisson, Ph.D.
Research agent

Faten studies the geomorphological processes affecting the Arctic coasts, particularly erosion caused by permafrost thaw and rising sea levels, creating risks of submersion. She focuses on the impacts of climate change, such as the reduction of sea ice and changes in meteorological conditions, which disrupt local ecosystems. Using advanced technologies like remote sensing and numerical modeling, she collects and analyzes data to improve coastal resource management and raise public awareness of environmental issues.
Ph.D. Students and Postdoctoral fellows
Clémentine Fanton, M.Sc.
Ph.D. Candidate in geography
Université du Québec à Rimouski
Clémentine is currently a PhD student between France and Quebec, working on the influence of North Atlantic storms on the western coastlines of Iceland. Her research focuses on shoreline morphogenic dynamics induced by extreme waves and high water levels. To this end, she conducts annual spring field campaigns in Iceland, using drone flights, sedimentology and DGPS monitoring to carry out topo-morphological analyses of beaches. The aim is to gain a better understanding of the diversity of morphological and sedimentological conditions in the face of extreme hydrodynamic forcing in this sub-Arctic region, based on in situ observations.
Ana Heras Duran, M.Sc.
Ph.D. Candidate in oceanography
University of Alberta
Ana is a PhD student working with Prof. Didier and Prof. Myers as part of the Ice2Ocean project which is a community-based project in the Canadian Arctic Archipelago. They work in collaboration with the Ausuittuq hamlet and its research is focused on understanding the marine physical dynamics in Jones Sound, the distribution and evolution of the Atlantic Water in the region and its impacts on glacier melt, using both, numerical model outputs (Nucleus for European Modelling of the Ocean) and observations (CTD and mooring). She also plan to characterize glacial retreat by remote sensing on several glaciers in the region.

Yohan Quénet, M.Sc.
Ph.D. Candidate in oceanography
Université du Québec à Rimouski
Yohan studies the morphodynamic changes of a beach at the Cambridge Bay site in Nunavut. Using measurement instruments, a video camera, and surveys conducted during ice-free periods over the past two years, he aims to identify the processes responsible for the site’s erosion. In addition to the in situ study, he also investigates the decadal variability of the system using satellite data to examine geophysical processes such as shoreline evolution and incident wave conditions. He is pursuing his Ph.D. in oceanography at UQAR under the supervision of David Didier (UQAR), Stéphanie Coulombe (POLAR), and Stéphane Bertin (CNRS).
Sima Teimourianmotlagh, M.Sc.
Ph.D. Candidate in oceanography
Université du Québec à Rimouski
Sima, a PhD student in oceanography, is studying long-term coastal migration patterns in Nunavut under the supervision of David Didier and Simon Bélanger. Her research focuses on spatiotemporal variability, coastal exposure mapping, and the identification of vulnerable hotspots. By analyzing satellite imagery and climate data, she investigates the factors driving coastal changes. Utilizing remote sensing, Sima maps regions with significant coastal migration and develops a framework for coastal adaptation in the Canadian Arctic Archipelago. Her work aims to produce detailed maps of coastline positions, insights into coastal exposure trends, and assessments of communities most affected by coastal migration.

To accomplish this, Sidik employs deep learning techniques, particularly Convolutional Neural Networks (CNN), to analyze and classify the various ecological zones of Nunavik. The objective of his research is to provide precise and automated mapping of coastal ecosystems, thereby facilitating the management and preservation of these sensitive environments.
