Giovanni Ramirez

Postdoctoral Appointee

Giovanni Ramirez is a Colombian researcher who received a Ph.D. in Engineering, specializing in thin films/coatings, corrosion and surface engineering, from the National Autonomous University of Mexico. Currently, he is a postdoctoral researcher at Argonne’s Tribology Section at Energy Systems Division.

At Argonne, he is working on numerous research projects dealing with development and characterization of thin films and coatings for different applications. He has participation in research activities that are both basic and applied in nature, and directed toward reducing energy consumption and understanding of the underlying fundamental mechanisms involved in the tribological behavior of many types of coatings and lubricants.

His areas of interest/expertise are: high performance tribological coatings, nanolubrication, thin film deposition, super hard coatings, nanocomposite materials, corrosion resistance coatings, biocompatible materials and coatings, and surface characterization
