Susan Alberts (

Susan is the head of the lab.





Laurence Gesquiere (

Laurence is a senior research scientist in the lab.  She manages the hormone research and runs the hormone lab.  Her research centers on projects in behavioral endocrinology and behavioral ecology largely focused on the wild baboon population of Amboseli.  Her ongoing research includes patterns of “cross-sex” hormones:  estrogen in male and testosterone in female baboons, and age-related changes in baboon physiology.


Jake (1)

Jake Gordon (

Jake is the lab’s data manager. He maintains our online database, and oversees entry of our behavioral data.  Jake also maintains the online records of our archives of baboon tissues, DNA, and RNA.



Allison Galezo (

Ali joined the lab as a PhD student in 2018.  She is broadly interested in sexual conflict, sexual selection, and the evolution of alternative mating strategies.



Sophie Brenner (

Sophie is a lab technician in the hormone lab and assists with the lab procedures for the extraction, purification and analysis of hormones from the feces of the Amboseli baboons.


Matthew Zipple




Matthew Zipple (

Matthew is a Ph.D. student in the lab.  He is broadly interested in questions of behavioral ecology.  He is especially interested in the fitness implications of interactions between adults and immature individuals, and how such interactions shape social structures and behaviors.



Liz Lange (

Liz joined the lab as a postdoc in Spring 2020.  Her research combines evolutionary studies, animal behavior, genetics, and theoretical modelling to understand when and how individuals use information from the social environment to alter phenotypes.





Emily Levy (

Emily is a Ph.D. student in the lab.  She studies interactions between environment, physiology, behavior, and fitness.  She currently studies relationships between and organism’s environment – social and physical, early-life and adult – and its physiology and morphology.
