Eileen A. Lacey is the Class of 1933 Chair in Biological Sciences and Professor in the Department of Integrative Biology at UC Berkeley. She leads the Lacey Lab based at the Museum of Vertebrate Zoology, focusing on vertebrate social behavior and population biology. Her research emphasizes evolutionary causes and consequences of social behavior in mammals, particularly subterranean rodents from Argentina and Chile. She combines field studies with genetic analyses to explore ecological drivers of sociality and genetic impacts of social living. Educational background: Not explicitly stated in text but inferred as PhD in Zoology/Behavioral Ecology from a top-tier university. Current lab members include PhD students Shannon O'Brien, Kwasi Wrensford, Erin Person, and Daisy Horr. Recent projects involve neuroendocrine mechanisms of dispersal in tuco-tucos and gut microbiome studies in social rodents. Research interests include evolutionary social behavior, behavioral ecology, molecular genetics, and conservation genetics. She maintains a captive colony of colonial tuco-tucos and collaborates with the MVZ's Evolutionary Genetics Laboratory. The lab actively promotes diversity and inclusion in STEM through anti-racist initiatives and educational outreach programs. Scientific achievements include groundbreaking work on MHC diversity in social rodents and ecological drivers of group living. Recent recognition includes NSF postdoctoral fellowships for lab members and awards like the Ford Foundation Dissertation Fellowship. The lab's work has been featured in journals like Behavioral Ecology & Sociobiology , Hormones and Behavior , and Journal of Mammalogy . Lab operations emphasize fieldwork in Argentina, California, and other global sites with captive colony studies. Future projects include investigating reproductive isolation mechanisms in California voles and the mechanistic underpinnings of social behavior in hyenas and ground squirrels.
