June 23, 2022 – Thunder Bay, Ont.
Lakehead University researchers are receiving more than $2.4 million in funding from the Natural Sciences and Engineering Research Council of Canada.
Dr. Adam Algar, Associate Professor in Biology, is receiving a Discovery Grant for $235,000 to understand how species’ ecological limits are responding to rapid climate and land use change.
Dr. Algar will use lab experiments, field studies, remote sensing, and big data modelling to spend five years exploring what stops species from spreading outwards, to all environments.
Understanding what limits, or promotes, species’ geographical spread can have considerable conservation, economic, and health implications through effects on at-risk species, the spread of invasives, and even zoonotic disease risk.
“This research will shed new light on the mechanisms underlying species’ range limits and improve our ability to predict species’ geographical fates as rapid environmental change reshuffles global biodiversity,” Dr. Algar said.
Dr. Noah Phillips, Assistant Professor in Geology, is receiving a $142,500 Discovery Grant to study the strength of Earth’s plate-boundary-fault systems, where tectonic plates slide past one another. Fault systems host the world’s largest earthquakes and are zones of enhanced permeability and fluid flow through the Earth’s crust.
His group will spend the next five years trying to determine the strengths of strike slip fault systems in the middle to lower crust.
“This study will constrain the strengths of rocks deforming under elevated pressures and temperatures in the crust at 10 - 30 km depth,” Dr. Phillips said.
“These rocks slowly creep past one another at a relatively consistent rate to accommodate the motion of tectonic plates. Understanding their strengths is important as this slow creep loads the locked portion of tectonic plates at shallower depths which deform suddenly to produce earthquakes.”
Understanding how rocks and minerals deform is critical because it directly controls the evolution of planet Earth; and impacts society by producing earthquakes, modifying landscapes, and forming/trapping mineral and water resources.
Dr. Leila Pakzad, Associate Professor in Chemical Engineering, is receiving a $140,000 Discovery Grant to help address fundamental challenges related to medical inhaler device design.
Effective treatment of respiratory diseases depends on the properties of the aerosol/particles/droplets produced by the inhaler and the drug deposition efficiency in the lungs, which requires understanding drug particle aerodynamic behavior.
Despite advances in inhaler device technology, the efficiency of drugs using inhalers, known as drug deposition efficiency, is only 10 to 50 per cent.
Dr. Pakzad’s research in multiphase (solid/liquid/gas) flow focuses on interactions between solid particles, liquid droplets, and gas bubbles in drug inhalation systems.
“The short term objectives are to understand the mechanisms of multiphase flow during drug aerosol delivery by pressurized meterdose, dry powder, and soft mist inhalers; and to develop computational fluid dynamics models to simulate inhaler mouth throat pathways,” she said.
“The long term objective is to link drug deposition to inhaler design and operation and ultimately to drug deposition efficiency.”
Over the next five years, Dr. Pakzad’s research team will use experimental, numerical, and theoretical methods to address fundamental challenges related to inhaler device design. The team will assess the performance of inhalers, provide guidance to upgrade current designs, and facilitate the design of new devices.
This research will train highly qualified personnel in multiphase flow, drug delivery systems, and advanced computational techniques, supporting future economic development in Canada.
Dr. Andrew P. Dean, Lakehead’s Vice-President, Research and Innovation, congratulated each researcher receiving funding from NSERC and he thanked the agency for its continued support of STEM-based research at Lakehead University.
“Funding from the NSERC Discovery program is so important for our researchers and in particular our Early Career researchers,” Dr. Dean said.
“The list of successful researchers shows once again the incredible diversity of research in Science and Engineering at Lakehead University.”
In 2020/21, Lakehead University received nearly $2 million in assistance from the Research Support Fund to support the indirect costs of research, which includes costs for supporting the management of intellectual property, research and administration, ethics and regulatory compliance, research resources, and research facilities.
