Rajvinder Kaur

Profile picture of Dr. Rajvinder Kaur

Rajvinder Kaur is currently working as a Research Associate in Prof. Lefsrud’s group and is leading the genetic transformation aspects of the field pea to enhance the oil content. Rajvinder’s research in graduate and postdoctoral studies has always been focusing on the value-added products. She has a unique combination of skills, which includes biological chemistry, microbiology and biotechnology. She obtained her Ph.D. in 2004 from the Australian National University, Canberra, Australia and did her Post-Doctoral training on genetic transformation and biotechnology at the University of California, Berkeley, USA where she worked on sorghum to improve digestibility and lysine content in the grains through particle–gun bombardment and agrobacterium infection. After completing her post-doctoral training, she joined as a Research Scientist at Chromatin Inc., Champaign, Illinois, USA where she led the genetic transformation of cereals and grasses to incorporate desired gene stacks for improvement of biomass and bioenergy capability.

Sarah MacPherson

Profile picture of Sarah MacPherson

Sarah’s love of biology stems from childhood summers spent near Pointe-au-Baril in northern Ontario. Sarah received her BSc. (Hons. Biology) from Concordia University in 1999 and was awarded her PhD from McGill University (Microbiology & Immunology) in 2005. This was followed by a postdoctoral fellowship in the Infectious Diseases Division at the University of Texas Southwestern Medical Center in Dallas, TX, where she helped develop an animal model for protective autophagy and arboviruses targeting the CNS. Since then, she has pursued her interests in science communication and teaching at the post-secondary level, in addition to working as a medical writer. Sarah joined the Biomass Production Lab and the Department of Bioresource Engineering as a Research Associate in 2018. Most recently, she coordinates the NSERC-funded graduate research program, Quality Assurance and Quality Control for Cannabis Production, Products and Training (now accepting graduate students).

Doctoral Studies

Philip Wiredu Addo

Profile Picture of Philip Wiredu Addo

I am a Schulich Fellowship award recipient pursuing the Doctor of Philosophy (PhD) program in Bioresource Engineering at McGill University under the supervision of Prof. Mark Lefsrud. My research focuses on the optimization of postharvest technologies for medicinal plants; cannabis and hops. This project will help establish optimal and improved conditions for drying of biomass and extraction of secondary metabolites which will lead to cost savings and create significant improvements in the production model for medicinal plants. This project also seeks to contribute to the development of standards for the industry. With rapid projected growth in the coming years for the cannabis industry, the development of cost-effective postharvest processes that preserve product quality will help producers in lowering their prices and compete in the global market to showcase Canada as a world leader in this field.

Sazan Rahman

Md Sazan Rahman is a Ph.D. candidate at the Department of Bioresource Engineering, McGill University. He is now working on HVAC control in porous concrete for green building elements. The main goal of his research is to keep plants alive on green roofs and walls in any weather conditions, where porous concrete will be used as a plant-growing substrate. He also aims to control indoor temperature and humidity by environmentally controlled green walls. Mr. Sazan is from a small village (Khoshalpur Nowpara) of Kalai, Joypurhat, Bangladesh. He has completed his BSc in Mechanical Engineering from Rajshahi University of Engineering & Technology (RUET), Bangladesh, and MSc in Mechanical Engineering from the University of Saskatchewan, SK Canada.

Sheida is working on the presence of humidity in greenhouses and HVAC systems known as a detrimental factor in terms of both energy saving and efficiency of the system. Sheida's project mainly focused on decreasing relative humidity in HVAC systems. Sheida received her M.Sc. in Agricultural Mechanization Engineering from the University of Tehran, Iran (2014-2016) and her B.Sc. in Agricultural Mechanization Engineering from the University of Tehran, Iran (2010-2014). 

Vincent Desaulniers-Brousseau

Profile Picture of Vincent Desaulniers Brousseau

Vincent is a PhD candidate working on next-generation hydroponic systems. His education includes two B. Sc. in Biological Sciences and Agroenvironmental Sciences and one M. Sc. in Molecular and Cellular Medicine. He is a trained agrologist and has a solid knowledge of biological systems. He hopes that biopharmaceuticals can one day be produced sustainably. Similarly to other advancement of other sectors, sustainable food, fiber and nutraceutical production lies in reusing what is usually discarded as waste. His research will help in making medical cannabis production environmentally friendly, enable growers with nutrition index for optimal cannabinoid production as well as increase environmental performance of plant production systems.
