Interpreted SNP data using bioinformatics to conduct. Assisted graduate students with understanding and conducting molecular techniques and trained, supervised and scheduled several undergraduate students working within our lab.
IV. University of Wyoming Wyoming Natural Diversity Database Field Technician 06/2015 – 09/2015
Conducted population, habitat and acoustic surveys of bats across remote regions in the state of Wyoming. Determined species, sex and health status of individuals. Deployed Song Meter 2+ equipment and identified canopy cover, ground cover and tree species within designated transects.
V. University of Guelph Canadian Center for DNA Barcoding
Molecular Laboratory Technician 05/2014 – 04/2015
Was part of a large team focusing on obtaining molecular barcodes of thousands of invertebrate and vertebrate species. Responsible for preparing specimens for DNA extraction, lysing cells, extracting DNA, editing and aligning sequences. Assisted one of the companies lead researchers in negative hit-picking and archiving DNA samples.
VI. McGill University Dr. Colin Chapman, Dept. of Anthropology
Laboratory Technician 09/2011 – 04/2018
Assisted in the primatology lab by organizing data collected across decades and converted hand written data into digital versions. Diagnosed gastrointestinal parasites by examining fecal smears of Ugandan primates.
VII. University of Guelph Canadian Pollination Initiative
Laboratory and Field Technician 05/2011 – 08/2011
Supported insect pollinator surveys across southern Ontario and northern Manitoba. Collected specimens using malaise, pit fall and pan traps in addition to sweep netting. Identified specimens collected to family level and furthering identification to genus level when possible.
VIII. University of Guelph Dr. Stephen Marshall, Dept. Environmental Science
Laboratory Technician 09/2010 – 08/2011
Assisted with the curation and organization of invertebrate specimens for the University of Guelph’s entomological collection. Mounted, labelled and classified specimens to the family level. Operated micro-optics system to develop high quality images of insect morphological traits to be used in publications or within undergraduate lectures. Tested unpublished dichotomous keys developed by graduate students.
