Using a variety of analytical and biomolecular approaches to reconstruct historic trends in organic inputs in the algal and cyanobacterial community composition in three Prairie reservoirs.
- Planned research projects to study and reconstruct the quality of water in Prairie lakes
exhibiting annual blooms of algae. I helped plan the sampling locations, collected
samples, performed extractions and conducted analyses.
- Wrote proposals and reports to grant agencies to apply for funding.
- Liaised a group of experts of different disciplines to collaborate on data collection and
characterization of sediment.
- Took specialized courses on environmental risk assessment and Federal and Provincial
environmental acts and regulations.
- Reconstructed trends in fecal pollution, in a sediment core collected from Ross Lake,
MB, through the identification and quantification of sterols and stanols using GC-MS
and HR-GC-MS methodologies.
- Reconstructed trends in the algal and cyanobacterial community from multiple
sediment cores collected from Lake Diefenbaker, SK, using pigment biomarkers and
HPLC-DAD instrumentation.
- Investigated for the presence of cyanotoxins in sediment and water samples from Lake
Diefenbaker using LC-MS/MS and Q-Exactive Orbitrap LC-MS methodologies.
- Identified the fragmentation pathway for a group of saxitoxins (paralytic shellfish
poisoning) using QTRAP and Q-exactive Orbitrap LC-MS methodologies.
- Reconstructed trends in the cyanobacterial community using next-generation
sequencing of the 16S and 23S rRNA genes from sediment cores collected from Lake
Diefenbaker and Buffalo Pound Lake, SK.
- Reconstructed trends in cyanobacterial toxin-producing genes (e.g. mcyA gene) from
sediment cores collected from Lake Diefenbaker and Buffalo Pound Lake, SK.
- Conducted whole genome sequencing on lake sediments.

Summer student
Summer student – Dr. Lorne Doig, Toxicology Centre, University of Saskatchewan
- Collection of fish from Fort McMurray using gill nets, euthanizing, identifying, and
processing of collected fish, and subsequent excising of fish tissue and blood samples
for dioxin and polychlorinated biphenyl analyses.
- License to operate company boats and aiding in the collection of surface sediments using
an Eckman grab sampler and collection and sectioning of sediment cores using a Glew

of experimental aquarium apparatus.
- Collection of sediment pore water, sediment surface water and surface overlying water
for various analyses.
- Hatching of lake sturgeon eggs and fish husbandry (e.g. feeding, cleaning, removal of
sick or dead hatchlings.
