Cesar O. Estien is a first-generation college graduate and Ph.D. candidate in UC Berkeley’s Department of Environmental Science, Policy, and Management in Dr. Christopher Schell's lab, focusing on advancing our understanding of how societal inequity and environmental injustice shape the ecology of cities. He is currently investigating the extent to which societal inequity influences wildlife biodiversity, biodiversity sampling, wildlife behavior, and human-wildlife interactions through an environmental justice lens.
Prior to arriving at UC Berkeley, Cesar completed his undergraduate degree at Florida State University, where he investigated how microplastics influence fertilization success in broadcast spawning organisms with Dr. Don Levitan. Following his undergraduate degree, Cesar worked at Benton Lake National Wildlife Refuge and Hastings Natural History Reservation before entering a post-bac position at the University of Cincinnati. During his post-bac, Cesar worked with Dr. Elizabeth Hobson to investigate how to use playbacks to manage non-native species and understand relationship dynamics. Throughout this time, Cesar served as the Marketing and Outreach Coordinator for ESA's Student Section where he helped develop a program that aided in the career development of students in ecology. While in this position, he led a manuscript that analyzed virtual conferences as a space for advancing diversity, equity, and inclusion. From 2021-2023, Cesar served as the Co-Chair for the Environmental Justice Section of ESA, where he led and assisted projects that aim to advance justice, equity, and inclusion, such as the EEB Language Project. Additionally, Cesar is involved with DEI initiatives with the Graduate Diversity Council (GDC) in ESPM, writes for the urban ecology blog Life in the City, and has created an outdoor program entitled "PEN".

My current work takes place within the Bay Area to understand the extent to which societal inequity and environmental injustice shapes biodiversity and wildlife ecology. My work uses a One-Health and environmental justice lens to more holistically investigate how the urban landscape impacts wildlife. Read more at cesaroestien.com
