Interests: Human behavioral endocrinology,
evolutionary perspectives on human behavior, human
reproductive ecology, human biology.
Anthropology
addresses profound issues of human origins and
diversity. Moreover, as a holistic and broad-minded
social science, anthropology is well-positioned to
integrate findings from an interdisciplinary
understanding of the human condition. The results of
such efforts may be valuable to a wide array of
concerns to social scientists, clinicians,
politicians, humanists, and intellectually curious
students. From this broad anthropological starting
point, I primarily obsess with questions concerning
the evolution and endocrinology of human behavior,
especially with respect to hormones and human family
life. Some of these research questions are: What are
the hormonal correlates of human pair bonds? How do
physiological responses during brief marital
interactions compare across cultural settings? What
are the hormonal correlates of human fatherhood? How
do early social influences impact adult neuroendocrine
function and behavior? As an aid to addressing
questions such as these, collaborators and I often
rely on minimally invasive biological sampling (e.g.,
saliva collection to measure testosterone levels). The
Human Behavioral Endocrinology Lab, housed in UNLV’s
Department of Anthropology & Ethnic Studies,
serves as an important resource facilitating such
research. The “lab” of the Las Vegas Strip also
provides fascinating insights into humanity and its
works.
