Elma González

Elma González (born June 6, 1942) is a Mexican-born American plant cell biologist. She is Professor Emerita of Ecology and Evolutionary Biology at University of California, Los Angeles. In 1974, she was appointed professor of cell and molecular biology at the University of California, Los Angeles. At the time, she was the only Mexican American female scientist in the University of California system. Professor Martha Zúñiga at the University of California, Santa Cruz, appointed in 1990, was the second. In 2004, the Society for the Advancement of Chicanos/Hispanics and Native Americans in Science recognized González with a Distinguished Scientist Award.

Early life and education

González was born in Ciudad Guerrero, in Tamaulipas, Mexico. She is the daughter of Efigenia and Nestor González, both migrant farm workers. She did not start school until the age of nine. As a teenager growing up in South Texas, and during college, Gonzalez worked as a migrant farm worker with her family picking cucumbers, cotton, and sugar beets. Traveling with her family to pick crops meant that González and her siblings started school late each year. Gonzalez went to college at Texas Women’s University (TWU) in Denton, Texas where she studied biology and chemistry. She later worked in a laboratory at Baylor Medical School in Houston, Texas, which motivated her to pursue graduate school in biology. She received her PhD in cell biology from Rutgers University in 1972. She did postdoctoral work in the laboratory of Professor Harry Beevers at UC Santa Cruz.

Career and service

In 1977, as an Assistant Professor, González was awarded a grant from the National Chicano Council on higher education sponsored by the Ford Foundation. The grant was designed to increase the number of Chicano faculty in U.S. higher education. She was promoted to associate professor at the University of California, Los Angeles in 1981, and then to full professor in 1993. At UCLA, González was the director of the Minority Access to Research Careers (MARC) program funded by the National Institutes of Health to support undergraduates completing their education and research projects in science. In 2005, she was the recipient of the University of California, Los Angeles' first Distinguished Teaching Award for "superb mentorship" to undergraduates engaged in scholarly activities.

Research

González is a plant cell biologist who studied the biological process of calcification in a group of algae known as coccolithophorids. She has written about the unusual ability of coccolith vacuoles to facilitate calcification, a significant part of the global carbon cycle. An ATPase removes protons in exchange for ATP from the vacuole, allowing the formation of carbon dioxide, a mechanism linking photosynthesis with calcification. She has suggested that an increase in ocean acidification together with increased nutrients might negatively impact the adaptive value of calcification.
