& Bioethicist


I am a cultural anthropologist with extensive training in science and technology studies, gender studies, and empirical bioethics. My work challenges entrenched scientific and medical beliefs about gender, sexuality, and the body across a range of specialized topics. The research and writing that results is deeply interdisciplinary, but singularly focused—on the promotion of social justice.

I am currently writing a book, T: The Unauthorized Biography that examines the varied identities of testosterone in U.S. culture. In collaboration with Rebecca Jordan-Young, the title is under contract with Harvard University Press and has support from the National Science Foundation and the Brocher Foundation, as well as a Guggenheim Fellowship and an American Council of Learned Societies Collaborative Research Fellowship.

This book stems from my work on “sex testing” and sports policies that ban women athletes for having naturally high testosterone. This research has appeared in ScienceThe American Journal of Bioethics, and BMJ. Later, I contributed to Dutee Chand’s successful appeal of the IAAF’s hyperandrogenism regulation at the Court of Arbitration for Sport, and served as an expert witness in the hearing.

I began my career looking at controversies over treatment for people with intersex traits, which resulted in an award-winning book, Fixing Sex: Intersex, Medical Authority, and Lived Experience (Duke 2008).

My research has been covered in the New York Times, Time, BuzzFeed, The Week, CNN, ESPN, The Daily Beast, The Los Angeles Times, Boston Globe, Jezebel, Slate, The Advocate, La Liberation, The Chronicle of Higher Education, San Jose Mercury News, and the Toronto Star. I’ve also appeared on The WorldBBC, CBS News, NBC News, KCBS, CTV News, Q Radio, Al Jazeera, and the Australian Broadcasting Corporation, among others.
