  • About me

    Pictured with the orangutan that inspired my dissertation

    I am interested in sex differences in growth and development of the skeleton in great apes and humans. A running theme in my work is busting the idea of a sex binary.

     

    I am a PhD Candidate at University of Pennsylvania and NSF GRFP Fellow. I earned my B.S. in Biological Anthropology from George Washington University, where I studied gorilla dental development and wrist bone shape.
