Robert Amaro


Teaching Associate Professor
Brown Hall W470E

Robert Amaro is formerly a staff scientist in the Materials Reliability Division at the National Institute of Standards and Technology in Boulder, Colorado.  He specializes in modeling of environmental-fatigue interactions in metals.  His most recent research focuses on microstructure-informed predictive fatigue crack growth models of pipeline steels exposed to high pressure gaseous hydrogen. 

Dr. Amaro received his M.S. and Ph.D. degrees in mechanical engineering with a focus on materials performance from the Georgia Institute of Technology.  Prior to attending graduate school, he co-owned a consulting engineering design/build firm and worked as a consulting engineer to the entertainment industry.

Dr. Amaro is a United States Department of Commerce Bronze Medal Award recipient, the highest honorary recognition given by the Department for significant performance characterized by outstanding or significant contributions that have increased the efficiency and effectiveness of the National Institute of Standards and Technology.
