Guillermo Douglass-Jaimes
Environmental Planner
Pomona College

Guillermo Douglass-Jaimes, the son of Mexican immigrants, is a first-generation college graduate and Assistant Professor in the Environmental Analysis Program at Pomona College.

His work is situated in global health equity and is driven by an interest and inquiry in how conceptions of place and identity can be products of social marginalization as well as sources for community resilience.
