Anthropology

Krista Milich, PhD
Assistant Professor

Krista Milich is a primate behavioral ecologist and socioendocrinologist with an interest in reproductive physiology and sexual selection. Her work aims to understand the proximate and ultimate mechanisms associated with the evolution of primate social systems and to use that knowledge to inform primate conservation efforts. Her current work also includes studying Zika virus and the gut microbiome. Milich earned her doctorate from the University of Illinois at Urbana-Champaign and joins us from a postdoctoral appointment at the University of Texas at Austin. Outreach projects include a collaborative initiative to reduce crop raiding in Uganda.

 

Helina Woldekiros, PhD
Assistant Professor

Helina Woldekiros' areas of specialization include subsistence and economic anthropology, bioarchaeology, foodways, human–animal interactions, and African archaeology. Her work focuses in part on human adaptations in the Horn of Africa during the beginnings of food production. Woldekiros completed her dissertation at Washington University in St. Louis before receiving a Volkswagen postdoctoral fellowship at Ludwig Maximilian University in Munich, Germany. She then returned to WashU, where she recently served as a postdoctoral associate. This fall, her team unearthed the oldest known physical evidence for the introduction to domesticated chickens to the continent of Africa.

 

Emily Wroblewski, PhD
Assistant Professor

Emily Wroblewski is a geneticist investigating the population and evolutionary immunogenetics of the major histocompatibility complex (MHC) in African apes (chimpanzees, bonobos, and gorillas). MHC molecules are critical to the immune response to infection and also influence other essential, but often competing, fitness-related functions such as reproduction and social behavior. During her doctoral work at the University of Minnesota, Wroblewski investigated patterns of paternity and the influence of paternal relationships on chimpanzee social behavior in the population of Gombe National Park, Tanzania. Most recently, she served as a postdoctoral fellow and research scientist at Stanford University.

 

Biology

Keith Hengen, PhD
Assistant Professor

Keith Hengen’s research interests are rooted in the homeostatic self-organization of intact neural networks that support sensation, perception, and cognition, and how appropriate information transmission in these systems is established during development and disrupted in disease. Hengen most recently served as a postdoctoral fellow at Brandeis University. Previously, as a doctoral candidate at the University of Wisconsin-Madison, he studied brainstem respiratory networks in hibernating ground squirrels. Hengen’s new neuroscience laboratory at Washington University investigates the role of sleep and wake in chaperoning the interactions between distinct plasticity mechanisms.

 

Rachel Penczykowski, PhD
Assistant Professor

Rachel Penczykowski is broadly interested in the ecology and evolution of host–parasite interactions, and how ecological context affects the risk of infection and consequences of disease for hosts. Her research involves a combination of observational studies of natural populations and communities, manipulative experiments in the field and lab, and mathematical models. Penczykowski has held postdoctoral appointments at the University of Wisconsin-Madison and at the University of Helsinki, Finland. She earned her doctorate at the Georgia Institute of Technology, where her work was supported by a National Science Foundation Graduate Research Fellowship.
