Alejandro Quezada
MSc student
Since the beginning of my research experience, I always wanted to focus on climate change to reduce greenhouse gas emissions. During my undergrad studies at Universidad Autonoma Metropolitana (UAM) in Mexico City, my desire to get more involved in waste management to produce greener energies guided me to collaborate in the initial stage of Sargassum’s anaerobic digestion for biogas production towards the design of an anaerobic digestor to counter the excessive growth of these algae over Mexico’s coast. At the end of that period, I wanted to learn more about biogas production from a different perspective. With Mitacs support I was able to attend a summer research internship at UBC Faculty of Forestry. At the forest product biotechnology lab, I identify that through pulp-based biorefineries there are different kinds of waste that could be used to produce greener energies. Today, as my graduate studies are getting started. I decided to get more involved in organic waste management practices for sustainable development considering both pathways anaerobic digestion and aerobic compost. To measure their global impact and gather data to help strengthen Canada’s science capacity to accelerate actions towards achieving net-zero emissions by 2050 in Canada.

Stuart Downie
MSc student
I originally hail from Hamilton, ON. I earned my HBSc at Trent University in Peterborough, where I majored in Environmental Science and minored in Chemistry. After my undergrad, I worked for a Waste Management/Agricultural company that land applies treated sewage on cash crop farms in Southern Ontario. I love to cook, read, and go on hiking and camping excursions. I play drums in a band back in Hamilton, and I also play guitar and piano, albeit rather poorly. My research involves monitoring the impacts of compost, biosolids, and manure on various soil characteristics and SOM fractions over a 12-month period. This will be analyzed using conventional wet chemistry as well as spectroscopic techniques. Soil spectroscopy is a novel rapid, inexpensive, and non-destructive technique for soil analysis. Spectra obtained by scanning soil samples with known chemical characteristics can be modelled and used to predict characteristics of unknown samples. My research will assess the accuracy of using soil spectroscopy to measure soils when they have been incubated with organic amendments.

Charlie Little
MSc student
My name is Charles (Charlie) Little, I am originally from Ontario, and I am a graduate student under Dr. Price. Prior to starting my masters, I completed my BSc (agriculture) here at Dalhousie’s Agricultural Campus with a double major in animal and environmental science; also obtaining a certificate in animal welfare. I have always enjoyed being outdoors in whatever form that may take and have always had a passion for both animals and the environment. While at Dalhousie’s Agricultural Campus I have enjoyed working on the campus farm for three academic years and two summers, taking on a high degree of responsibility in the ruminant animal centre (RAC) and the cropping unit. My most recent summer, however, was spent as a research student for Dr. Price, where I gained valuable insight into how a graduate level research laboratory is run and was able to learn how to use much of the equipment. I am now into the first year of my masters, developing my thesis; I am looking at the quantification, characterization, and analysis of microplastics in biosolid amended agricultural soils and the potential implications for soil health.

Charlie Parent
MSc student (defended 2023)
Hi my name is Charlie Parent and I was born here, in Nova Scotia but moved to Manitoba at a very early age. I was raised in Winnipeg where I attended and graduated with an Environmental Engineering and a minor in Agricultural Business from the University of Manitoba in early 2019. After graduating I moved to Nova Scotia in search of something new. I quickly found myself falling in love with craft beer and began managing a microbrewery in the Valley. However, during this time, I kept coming back to the idea of continuing my education and building my research skill set. In the fall 2020, I began my M.Sc. studies in the Innovation Waste Management Research Program at Dalhousie in the Agricultural Faculty. My studies focus on biochar and biochar-alginate composites as adsorbents of Lead (Pb) from wastewaters and drinking water. These materials are anticipated to support development of novel, lower cost solutions for remediation of contaminated water systems or for wastewater treatment. During my M.Sc. I have continued working and managing a microbrewery, New Scotland Co. in Dartmouth. Over the past couple years I have been lucky enough to grow my research and laboratory skill set while gaining hands-on experience with microbrewing.
