Dr. Xiaopeng Gao (2012-) is a research associate in the Applied Soil Ecology Lab and also a research scientist in the Chinese Academy of Science. His current research programs concentrate on the impact of agronomic practices on reduction of greenhouse gas emissions from soils. Dr. Gao is highly experienced and interested in the research areas of development and modeling of 4R management strategies to reduce N2O emissions from agricultural systems.
Faith Omonijo (2019-) is a research associate in the Applied Soil Ecology Lab and co-supervised by Christine Rawluk (NCLE Research Development & Communications Coordinator, University of Manitoba). Her responsibilities include: conducting a literature review on the sustainability of pig production in Canada; providing a comprehensive review that identifies gaps in knowledge to environmental indicators of sustainability and details approaches and results of past pig production surveys in Canada; and evaluating environmental footprint approaches and tools. Faith’s reviews will assist with the design and development of a pig production survey and environmental footprint assessment for Canada, as part of the Lab’s Swine Science Cluster project, Advancing the Canadian Swine Sector Through Environmental Footprint Analysis.
Mingyuan Yin (2018-) is a visiting PhD candidate from the Chinese Academy of Sciences. During his tenure with the Applied Soil Ecology Lab, he worked under the supervision of Dr. Xiaopeng Gao to study the relationships between nitrous oxide emissions and associated functional genes (nitrifier and denitrifier) for agricultural and natural ecosystems. Mingyuan’s visit was funded by the China Scholarship Council – University of Manitoba Joint Scholarship Program. Thesis: Emissions of N2O from Grassland Ecosystem Under Different Grazing Intensities on Kunlun Mountain in Southern Xinjiang, China.
Mick (Mike) Runzika (2017-) is a PhD candidate investigating nitrogen cycling processes in soil using 15N isotopes, and how these processes contribute to the atmospheric loading of N2O. He is investigating N2 fixation by soybean using the 15N dilution method, N2O emissions associated with N2 fixation, rotational nitrogen benefit of soybean to a subsequent spring wheat crop, and the contribution of soybean residues to N2O emissions. Mick will use his research to develop N2O emission factors pertinent to soybean residues in Manitoba. Lastly, his thesis project will examine the contribution of different pathways (e.g. nitrification and denitrification) to N2O emissions using the 15N pool dilution techniques and how these pathways are affected by different soil conditions. Thesis: The use of 15N Isotopes in the Study of N2O Emissions in Soil
Wennong Kuang (2017-) is a visiting PhD candidate from the Chinese Academy of Sciences. During his tenure with the Applied Soil Ecology Lab, he worked under the supervision of Dr. Xiaopeng Gao on 4R nitrogen fertilizer management practices to reduce soil nitrous oxide emissions from cropland. His thesis project compliments several of the Lab’s current research projects. Wennong’s visit was funded by the China Scholarship Council – University of Manitoba Joint Scholarship Program. Thesis:
Study on the Mechanism of Water and Fertilizer Management on N2O Production and Emission from Cotton Fields in Arid Regions of Northwest China
Nazanin Ghavami (2016-) is a PhD candidate investigating Manitoban soybean fields for the presence of the soybean cyst nematode (SCN), Heterodera glycines. Her project continues from surveys conducted from 2012 to 2015 that did not find the nematode. SCN is one of the most devastating disease/pest organisms of soybean worldwide and is found in all major soybean growing regions of the world, including Ontario and Quebec in Canada. It is expected to soon be present in Manitoba as the pest has progressed northward in Minnesota and North Dakota to reach the Manitoba border. Early detection of SCN before it establishes in Manitoba is critical to limit yield losses. Nazanin will also use her research to develop molecular protocols for quantification of SCN calibrated to traditional microscopic counting of eggs to replace the laborious and error-prone extraction/observation that currently exist for SCN quantification and identification. Thesis: Survey and Development of Molecular Soil Test for Soybean Cyst Nematode in Manitoba
Priscillar Wenyika (2016-) is an MSc student studying the economically important root-lesion nematode, Pratylenchus neglectus, which parasitizes crops including cereals, legumes and brassicas. A recent survey for plant-parasitic nematodes revealed the presence of P. neglectus in some Canadian Prairie Provinces farm fields. Priscillar’s research includes screening seven common Prairie crops (canola, chickpea, lentil, pinto bean, spring wheat, soybean, and yellow pea) to determine their host suitability for P. neglectus. To achieve this, she grew these crops in soils naturally infested with P. neglectus, and at the end of an 8-week plant growth cycle, examined the roots and soils for the presence of P. neglectus. Priscillar will compare the initial and final nematode density to determine the nematode reproductive factor (Rf) and host suitability of each crop. Thesis: Host Preference for Pratylenchus neglectus Among the Major Crops Grown in the Canadian Prairie Provinces
Amber Aligawesa (2019-) is a soil and plant chemistry research technician in the Applied Soil Ecology Lab. Her responsibilities include processing soil and biomass samples, conducting nutrient extractions, and assisting Mervin Bilous with analyses using the Technicon auto-analyzer and CNS dry combustion analyzer.
Lanny Gardiner (2017-) is a research agronomist in the Applied Soil Ecology Lab. Lanny engages commercial farmers to obtain access to farmland for field trials.

She has recently become involved in the collection and analysis of spectral reflectance measurements taken over the canopy of cropping systems (corn, wheat, oats, soybeans and canola) using an unmanned aerial vehicle as well as handheld instruments in order to determine soil and vegetation water contents and, ultimately, crop health.
Terri Fairman (2014-) is a molecular biology technician in the Applied Soil Ecology Lab. Terri maintains the molecular biology lab and conducts molecular diagnostics of soil-borne crop pathogens such as fungi (e.g. Verticillium spp.) and nematodes (e.g. Ditylenchus spp.).
