Freshwater Ecology Data Analyst | R & QGIS | Water Quality & Community Ecology

Profile Summary

I am a PhD in Ecology specializing in freshwater ecosystems, with strong experience in ecological data analysis and spatial analysis. I work with R and QGIS to analyze water quality data, freshwater biological communities (microalgae, fish fauna), and spatial relationships at watershed and regional scales. My work focuses on reproducible analysis, clear statistical outputs, and publication-quality figures. I prefer written, asynchronous communication to ensure analytical accuracy and high-quality deliverables.
