Rachel Charish

Project Scientist

Email: rc@smruconsulting.com

Rachel Charish joined SMRU Consulting as a Project Scientist in 2022. Rachel is a marine acoustician with an interest in understanding anthropogenic impacts on cetaceans. Rachel first became interested in cetacean ecology while working as a marine naturalist for a whale watching company based out of the Canadian Pacific Northwest. She developed cetacean identification skills during this time and an awareness of the anthropogenic impacts associated with underwater noise. Rachel subsequently enrolled in an interdisciplinary MSc program at Ghent University with study semesters in Spain, Italy and Ireland, and carried out coursework on MPA Management, Marine GIS and Spatial Planning, and Marine Acoustics. Rachel’s graduate research involved analysing C-POD data to model trends in dolphin and harbour porpoise presence and foraging on the west coast of Ireland. Rachel has completed several contracts processing spatial and acoustic datasets for Wildlife Conservation Society Canada. In addition to Rachel’s experience analysing data and reporting scientific results, Rachel has a background in stakeholder engagement and science communication.
