VICKSBURG, Miss.— Since 2019, Quincy Alexander, a research civil engineer at the U.S. Army Engineer Research Center (ERDC), has been shining a light on common barriers relating to diversity, equity and inclusion (DEI) that are often faced in the workplace. DEI is used to describe policies and programs that encourage equitable treatment for people of different ages, races, cultures, disabilities, religions and more. Examples of commonly documented barriers in the technical workplace include biases in recruitment and hiring, social capital and stereotype threat.
