Carissa Mayo

Quantitative Ecologist & Data Scientist

I am an applied scientist passionate about utilizing statistical and computational modeling to bridge the gap between data and real-world impact. I am currently completing my M.S. in Quantitative Ecology and Resource Management at the University of Washington, where I model disease transmission in clam populations using Bayesian methods. My background in statistics and data science from the University of Colorado provides the quantitative foundation for my work in statistical methods, computer science, and data analytics.

Beyond Research

Outdoor activity

Outside of research, you'll find me exploring the Pacific Northwest outdoors or traveling. I am passionate about hiking, skiing, scuba diving, photography, and spending time on the water. These experiences fuel my curiosity about the natural world and remind me why conservation matters.
