Research Interests Dr. Walker's primary research focus is suicide and depression in African-American adults. Research models that integrate psychological, biological, and cultural phenomena will advance psychological science particularly for African-Americans and other underrepresented groups in the U.S. As such, Dr. Walker has bridged several interrelated areas-- measurement of depression and negative emotionality, psychosocial and cultural factors in resiliency, and gene-environment vulnerability to psychological problems.
