Welcome to Eun-Joo Ahn, postdoctoral Associate Fellow in the Yale Center for the Study of Race, Indigeneity, and Transnational Migration with a secondary appointment as a lecturer in Physics.
Ahn is a self-described “astrophysicist turned historian of science”. Ahn explained, saying she is “examining the history of post Second World War transnational physics involving Asian American physicists, and the history of Mount Wilson Observatory. As an astrophysicist, I have worked in composition determination and hadronic interaction model of ultra high energy cosmic rays. I was part of the Pierre Auger Collaboration.”
Ahn is currently teaching the Yale College course PHYS 047: Asian Americans and STEM.
Ahn received her Ph.D. in astronomy and astrophysics from the University of Chicago in 2006 with the thesis “Early stages of ultra high energy cosmic ray air showers as a diagnostic of exotic primaries” and a second Ph.D. in History from the University of California Santa Barbara in 2023 with the thesis “Factory Observatory at Mount Wilson: Astronomy, Regional Development, and Place, 1900-1930.”
