Research

Plant-Microbial Interactions and Agronomy

A wide range microorganism colonizes the plant and plant-root interface, and these microorganisms can establish beneficial, neutral, or detrimental with their host plant. My current research program is focused on technologies that reduce the need for synthetic nitrogen fertilizers to grow crops by replacing them with more natural, biological resources. I employ both basic and applied research in my research program. Currently, I have three major focus areas: 1) assessment of beneficial microbes (probiotics) for improving nitrogen fixation in legumes and non-legumes; 2) evaluating beneficial microbes that can alleviate abiotic stress in plants; 3) discovering the physiological mechanisms and factors that influence nitrogen fixation and belowground nitrogen transfer from legumes to non-legumes. 

Courses

PL SC 499 - Cropping Systems

The cropping systems of Alberta are unique and specific to the diverse climatic regions of the province. This course will discuss crop and variety choices, crop rotations, nutrient requirements, agronomic management, soil health and pest management options within the context of environmental and economic sustainability. The course depends on interaction with agronomists, other professionals and researchers from across Alberta. Completion of a group project is a major component of the laboratory. Prerequisites: PL SC 355, REN R 210, and *6 from PL SC 324, PL SC 352, PL SC 380. PL SC 495 and REN R 445 recommended.

Fall Term 2020
