Dr. Schery Umanzor started her career in 2010 as a field assistant in food production-related projects. Her professional journey showcases a seamless transition from working on IMTA systems in the tropics to kelp restoration in Baja California, Mexico, to engaging in kelp selective breeding on the East Coast of the U.S. and eventually venturing into mariculture research in Alaska. Throughout her multifaceted career, Dr. Umanzor has consistently championed inclusive approaches to food production. Currently, Dr. Umanzor and her students are focused on developing cultivation protocols for red seaweeds and pinto abalone while continuing with kelp-related research.

Research Overview

For the past three years, Dr. Umanzor has focused on working directly with kelp farmers and seaweed harvesters to address stakeholder needs. These include developing toolkits for adequate site selection and tools enabling farmers to gauge the ecological impact of their farms by quantifying the amount of carbon and nitrogen removed from the water each growing season. It also includes developing cultivation protocols for species of cultural importance. As an experimental marine ecologist, part of her interest relies on quantifying how community-structuring organisms interact with the physical environment, and how these interactions translate to potential ecosystem services to coastal areas.
