I have a PhD in Biology with a specialization in Environmental Stress Physiology and Biochemistry, MSc in Horticulture (Plant Physiology), BSc (Hons) in Agriculture, ASc in General Agriculture. Post-doctoral Fellowship was in Environmental Stress Lipidomics and Neurolipidomics. My research approach and programs are very multidisciplinary and involves collaborations with other scientists or end users in government (Regional, Provincial and Federal), industry, and academia in the areas of agriculture, food science, analytical chemistry, biostatistics, neuroscience and nutritional biochemistry; to assess the roles of lipids in agriculture production, food and human health outcomes. Analytical expertise: (pressurize solvent extraction, mass spectrometry, chromatography and vibrational spectroscopy).

I completed PhD in analytical chemistry from University of Wollongong, NSW, Australia. During my doctorate research I contributed in the development of three mass spectrometric techniques namely OzID (ozone-induced dissociation), CIDn/OzIDn (combination of collision-induced dissociation and OzID) and RDD (radical-induced dissociation) in studying the small alternation in lipid structures and their impact on lipid metabolism. After graduation I have 3-year postdoc experience in University of California, Riverside, USA. I’m currently working at Memorial University of Newfoundland (MUN) as Postdoctoral Research Associate in Dr. Raymond Thomas's research group to develop analytical methods applying to a broad range of functional compounds including proteins, lipids, antioxidants, and evaluation methods in functional food research.

Grace Callahan

Email: gecallahan@grenfell.mun.ca

My honours project is on the effects of clearcut harvesting on moss chloroplast lipidome and adaptation to light stress during boreal forest regeneration. Clearcut harvesting represents a major anthropogenic disturbance in boreal forests following resource harvesting for the timber industry and may expose understory vegetation to environmental stress. Lipids may serve as biomarkers of stress response. By analyzing the lipid concentration of different moss species in forest and clearcut regions, we can better understand the ability of lipids in moss to change for survival. The objective of this project is to characterize moss chloroplast lipidome and evaluate the effects of clearcut harvesting on moss chloroplast lipids.

Supervisor: Dr. Raymond Thomas

Abayomi is a research scientist with background in Chemistry, Environmental Science (Toxicology), Food Quality Control and Assurance.

​He is currently pursuing his second PhD in Transdisciplinary Sustainability (Marine Functional Food Development Sustainability) at MUN-Grenfell campus. He joined the group in May 2022.

His research topic is Marine biomass Functional foods/Nutraceuticals development and production for nutrition, health, and coastal community sustainability.

This requires building capacity to address the 21st century transition to indigenous and global sustainability. The approach involves distant multidisciplinary expertise (natural sciences, social sciences, humanities, and fine arts), with inclusion of novel stakeholders and partners (government, indigenous communities, industries, NGO's) perspectives and interests external to academia through interactive and participatory research. This is a laboratory based indigenous and western knowledge (two-eyed) systems of characterizing Newfoundland’s marine biomass unique quality composition and safety applications in functional foods/nutraceuticals production and validation in nutrition, health, and coastal community business development and sustainability. This transdisciplinary green technology-based system would help to solve various complex ecological, socio-economic, cultural, coastal community and global issues in business and sustainable development.
