My early work was in the area of developmental psychology. I published papers in the
1970s and 1980s on children's play and drawings and adolescents' values. In the 1990s,
my interests began to change after I was accepted to participate in a summer research
program at Armstrong Laboratory at Brooks Air Force Base in Texas.
As a result of this program, I researched such areas as job analysis and personnel
selection. I spent four summers at Armstrong Laboratory. After the program ended,
I found a similar program at the Defense Equal Opportunity Management Institute (DEOMI). I spent nine summers there, performing research on test construction, equal opportunity,
and toxic leadership. I also spent one summer at Naval Personnel Research Studies
and Technology researching operational stress.
