It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.
—Conan Doyle, “A Scandal in Bohemia” in The Adventures of Sherlock Holmes


I use quantitative methods to study stratification and inequality based on sexuality and gender from a queer and feminist perspective. In particular, I am interested in (1) the association between sexual orientation and gender identity, and socioeconomic status in Japan, (2) sexual/gender minorities and social attitudes, (3) the measurement of sexual orientation and gender identity in quantitative research, and (4) queer and feminist methodologies.
