Paul Almeida is a Professor of Sociology and Environmental Systems at the University of California, Merced. Almeida’s research centers on the efficacy of collective action at the local, national and global levels of social and political life.  He has empirically examined the timing, distribution, and outcomes of dozens of large-scale campaigns whereby ordinary people and excluded social groups mobilized to protect themselves from the loss of vital necessities such as environmental quality, health care, pensions, water services/utilities, and other socio-economic rights. 

His recent work focuses on community-based challenges and responses to climate change. Since 2018, he has served as the PI/Co-PI implementing representative surveys with partner groups in towns and cities throughout the San Joaquin Valley on community needs and/or climate action. 

Almeida is a founding member of the UC Merced Community and Labor Center. He is an affiliate of Brown University's Climate Social Science Network (CSSN) and participates in the Valley Plan on Climate Investments, Jobs, and Technologies. He sits on the Climate Change steering committee of the University of California's Institute on Global Conflict and Cooperation (IGCC) and on the Decarbonization Board of UC Merced.
