Daiki Hiramori is currently an Assistant Professor in the Faculty of Global and Interdisciplinary Studies at Hosei University in Tokyo, Japan. His research interests include quantitative sociology, queer and feminist studies, sexuality and gender stratification, and the demography of sexual orientation and gender identity (SOGI). He graduated from the International Christian University in Tokyo, Japan, with a bachelor's degree in Sociology and a minor in Mathematics in 2014. He also earned an MA in Sociology in 2016, a Graduate Certificate in Feminist Studies in 2018, and a PhD in Sociology in 2022, all from the University of Washington.

He uses quantitative methods to study stratification and inequality based on sexuality and gender as well as sexual and gender minority populations from a queer and feminist perspective. In particular, he is interested in socioeconomic inequality based on SOGI, the measurement of SOGI on surveys, and queer and feminist methodologies. In his dissertation "Sexuality Stratification in Contemporary Japan: A Study in Sociology," he used the Osaka City Residents’ Survey, one of the few population-based surveys that ask about sexual orientation in Japan, to explore the association between sexual orientation and educational attainment, occupational segregation, and earnings disparities in Japan. His publications have appeared in the Journal of Population Problems and Gender and Sexuality. Through his research and educational activities, he is committed to using his privilege as a social scientist to focus on the ways in which systemically marginalized populations, such as lesbian, gay, bisexual, transgender, and queer (LGBTQ) people, become free in a system that operates to oppress them.
