I am a biological anthropologist by training and Professor of Anthropology and Health and Behavioral Sciences at the University of Colorado Denver. I also hold an appointment as Professor of Public Health at the University of Colorado Anschutz Medical Center.

My main area of expertise is human ecology; that is, the reciprocal relationship between organisms, in this case, humans, and their environments understood within an evolutionary framework. For the human organism, the “environment” includes the diverse physical, behavioral, and wider sociocultural milieus within which they are found and to which they must successfully adapt. To date my research has examined aspects of both human biology and behavior within such a framework. In the biological arena, my research has focused on various aspects of maternal and child health including nutrition, growth and development, and determinants of fertility. Within the area of behavioral ecology, I have been interested in testing predictions derived from life history theory and parental investment theory as well as an examination of social norms such as reciprocity, altruism, bargaining, and punishment. All of these areas are represented in my two-decade long and currently still ongoing field-based research project among the Au lowland forager-horticulturalists of Papua New Guinea.

My research among the Au has considered such topics as:
*effects of resource availability on birth interval duration
*cumulative effects of repeated pregnancies and prolonged lactation on women's health
*influences of maternal body composition on the effectiveness of breast-feeding as a natural contraceptive
*the effects of recently introduced socioeconomic development and social stratification on hemoglobin levels, birth weights and growth
*biases in parental investment by age, sex and condition of children and the effects of such biases on child growth and neuromuscular development
*effects of exposure to markets on the outcome of economic experiments used to gauge bargaining behavior, reciprocity and fairness
*effects of punishment on cooperation and fairness
*the propensity of individuals to remediate violations of social norms by punishing transgressors versus compensating victims
