Soil scientist and microbial R&D leader driving sustainable agriculture innovations.
CanadaWhat I'm looking for
I am a PhD soil scientist with 15 years of research experience in plant–microorganism–environment interactions, building multidisciplinary R&D programs and strategic partnerships across North & South America, Africa, and Europe. I specialize in microbial inoculants, microbial ecology, and soil health restoration to drive sustainable, profitable food production from soils to vertical farms.
At Earth Microbial Inc. I led R&D pipeline and protocol development, developed five commercial microbial inoculants, managed microbial genomic sequencing and bioinformatics, and secured North American and ECOCERT product registrations. I have designed labs and SOPs, trained cross-functional teams, and delivered technical support for product commercialization in resource-constrained environments.
I am pragmatic and problem-solving, committed to community service and climate-smart cropping practices, with a track record of competitive grants, teaching experience at University of Toronto and University of Waterloo, and 29 published scientific papers in high-impact journals.
