Postdoctoral Scholar

Ben Trumble is a postdoctoral scholar at UCSB who manages the Human Biodemography Lab.  His research focuses on human biodemography, exploring how the social and physical environment can impact human physiology.  His laboratory and field studies examine hormone-behavior interactions; specifically the relationship between testosterone, behavior, environment, and the implications this has for male health and life histories in industrial and forager-horticultural populations. His other research interests include biodemography of ageing, immune function, prostate cancer, risk taking behavior, costly signaling, and the development of population level biomarker assays.
