I am a cultural anthropologist working at the intersection of science and technology studies, theories of gender and race, social studies of medicine, and bioethics. My research and teaching examine—and challenge—scientific and medical beliefs about gender, sexuality, and the body across a range of topics. I am the Carol Zicklin Endowed Chair in the Honors Academy at Brooklyn College, CUNY and a Senior Research Fellow with the Global Health Justice Partnership at Yale University.

My latest book, Testosterone: An Unauthorized Biography, written with Rebecca Jordan-Young, unsettles a great deal of long-standing knowledge and beliefs about this wiley hormone. Forthcoming with Harvard University Press, this work was also supported by the National Science Foundation and the Brocher Foundation, as well as a Guggenheim Fellowship and an American Council of Learned Societies Collaborative Research Fellowship. A recent essay, "The Masculine Mystique of T,"  was published in the New York Review of Books.

My work on testosterone stems from my earlier research, including my research on “sex testing” and sport regulations that ban women athletes with naturally high testosterone. This research has appeared in ScienceThe American Journal of Bioethics, BMJ, and Feminist Formations. I contributed to Dutee Chand’s successful appeal of the IAAF’s testosterone regulation at the Court of Arbitration for Sport (CAS), and served as an expert witness in the hearing. I also consulted with Caster Semenya’s team prior to her CAS hearing.

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

My writing has appeared in the New York Times, The Guardian, Wired, and the New York Review of Books, among other outlets.

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.

I hold a doctorate in Cultural Anthropology and a Master’s in Public Health, both from Columbia University. Prior to my current position, I spent 15 years at the Center for Biomedical Ethics at Stanford University.
