The endowed TISED Chair in Sustainable Engineering and Design has a critical role in advancing the goals and objectives of TISED through leadership in research, teaching and outreach. The Chair鈥檚 research expertise and interests also encourage collaboration with others at our university and beyond. It is, therefore, with great pleasure, that TISED announces its first endowed Chair, Dr. Laxmi Sushama.聽
Dr. Sushama is an Associate Professor at the University of Quebec Montreal (UQAM) and holds a Tier II Canada Research Chair in Regional Climate Modelling (RCM).聽Prior to that, she has聽worked as a climate specialist on regional climatology and聽adaptation to climate change at聽Ouranos Consortium, Montreal. She was also a research聽associate and post-doctoral fellow in regional climate modelling with an聽emphasis on聽climate change and the regional hydrologic cycle at UQAM. 聽Before moving to Canada, she was a postdoctoral聽fellow in the Department of Atmospheric Sciences at the University of California, Los聽Angles. Dr. Sushama聽completed her Ph.D. in Civil and Environmental Engineering from the聽University of Melbourne, Australia.聽Dr. Sushama led the very first study to assess climate change impacts on Canadian water resources, based on high-resolution regional climate model simulations. This led to several other projects, including the NSERC-funded Collaborative Research and Development (CRD) project with Hydro-Quebec as an industrial partner.
Expertise in Regional Climate Modelling (RCM)
Dr. Sushama's interest is in regional climate modelling, particularly the representation of land surface processes and land-climate interactions. Interactions between the atmosphere and the underlying surface are important and determine the evolution of many simulated near-surface variables.聽聽Her research involves increasing the range and physical realism of surface processes represented in the high-resolution Canadian RCM. Dr. Sushama's group is involved in the development and adaptation of appropriate parameterizations to implement several聽important feedback processes in climate models. Feedbacks such as near-surface permafrost, lakes, rivers, wetlands, etc., are known to play important roles in high-latitude climates but are not represented adequately. Dr. Sushama's research is focused on Canada and the Arctic.
Policy implications for Advanced Land-Surface Modelling
Climate change, induced by the increased emission of greenhouse gases, is one of the greatest environmental threats today. These changes are being experienced particularly intensely in the Arctic. The primary tools used to study anticipated climate changes are the Coupled Global Climate Models (CGCMs) and RCMs, and the transient climate-change simulations obtained when these models are run.
As Canada Research Chair, Dr. Laxmi Sushama had聽one main research goal: to increase the range and physical realism of surface processes represented in the high-resolution Canadian RCM (CRCM). This will enable more accurate simulations of the surface/sub-surface climate over North America, including the Canadian Arctic. This includes permafrost, dynamic vegetation, lakes and rivers鈥攁ll of which will be modelled directly within the CRCM.聽The system developed by Sushama will be applied in climate-change assessment studies and will contribute to providing a solid platform from which Canadian provincial and federal governments can develop strategies to adjust to and plan for future climate change.
Visions for TISED and McGill聽
Dr. Sushama plans to聽set up a pole on climate change and sustainable engineering and design聽with a special emphasis on water resources/urban management and infrastructure at McGill with the support of TISED. She聽also hopes to聽facilitate climate change informed planning and design for all Engineering disciplines.聽
Her proposed research program on climate change and sustainable engineering and design will follow three main streams. The first stream will聽assess聽climate change's impacts on the hydrologic cycle, at local, regional and global scales, using Regional Climate Model (RCM) and Global Climate Model (GCM) simulations. It will also assess聽water resources and related infrastructure and its management through sustainable approaches.
The second stream will attempt to understand聽the interplay between various land surface (hydrologic) processes and their climate interactions in urban and high-latitude to Arctic regions, using RCMs, and sustainable urban/high-latitude/Arctic infrastructure development.
The third stream extends climate change information to facilitate appropriate impact and adaptation studies related to varied engineering projects (e.g. applications in the design of transportation network, energy sector).聽
聽The proposed research program will seek sustainable engineering solutions and informed decision-making to adapt to the projected near-future (next 20 to 30 years) and far-future (50 to 100 years) changes.
