Over the years, membership in the SNI has become an important distinction for researchers, since this selective recognition is given based on an independent peer evaluation, and symbolizes the quality and prestige of the scientific contributions of the researcher. However, this distinction had only been awarded only to researchers residing in Mexico.
This year, for the first time in SNI history, the organization has opened its membership to outstanding Mexican scholars living abroad.
Ruiz was accepted as a "National Researcher" under the organization's highest-ranking category for contributing researchers. He was recognized for his outstanding scientific contributions and efforts to enhance Mexico's scientific and technological capacity through collaborations with the UA and research institutions in Mexico.
"There are many important scientific questions that can be addressed in Mexico and that are pertinent to my field of study. These questions include environmental problems and fundamental issues about the tectonic evolution of Mexico," Ruiz said.
Ruiz is well known for his research involving the formation of metallic ore deposits. In particular, he studies the factors responsible for the origin of ore-forming elements in copper and gold ore deposits at or near the earth's surface.
His work has revealed that gold deposits also offer a method for studying the evolution of the atmosphere, specifically how the oxygen concentration has changed through time. He also is an expert in the tectonic evolution of southern Mexico. His research team addresses problems ranging from the origin of life to present-day climate change.
