Dr. George Lazarovits

Director of Research


​Dr. Lazarovits is a Plant pathologist (University of Toronto) with extensive experience on soil health and its microbiome. Before joining A&L Biological Inc. as Director of Research, Dr. Lazarovits worked as Research Scientist at Agriculture and Agrifood Canada for over 30 years. Dr. Lazarovits’ research over the last decade has focused on examining plant health from an ecological perspective where both beneficial and detrimental organisms in soil are considered to affect plant vigour. He developed innovative model systems for studying soil processes and interactions between microorganisms and plants, as well each other. Dr. Lazarovits’ studies now focus on identifying how populations of soil microorganisms impact plant health. He works closely with growers and industry and his efforts have benefited producers through improved produce quality and more sustainable cropping systems.

Dr. Keri Wang

Microbiology Laboratories Director, Senior Scientist


Dr. Keri Wang graduated with Ph.D. degree in molecular plant pathology from the University of Alberta. Dr. Wang has worked on molecular mechanism of plant disease resistance and plant-microbe interactions by functional genomic approaches like virus-induced gene silencing (VIGS) and gene expression profiling, functional genomics and microbial ecology of plant growth promotion rhizobacteria, molecular epidemiology and biodiversity of phytoplasma diseases. He has expertise in plant pathology, microbiology, molecular biology, and biotechnology with 25 publications in peer-reviewed journals and 34 presentations in national and international conferences. He has developed and modified many methods for research and services. Currently, his work covers development and validation of methods for the rapid and sensitive detection, identification and enumeration of foodborne pathogens; plant disease diagnostics; development of attenuated viruses for management of virus and bacterial diseases; isolation and characterization of glyphosate degrading bacteria. Keri has recently reported two new viruses in cannabis, first reported cannabis phytoplasma disease in Canada. More cannabis viruses are being identified in his research.
