Research Statement
My research is not restricted by disciplinary boundaries; it integrates the sociological problem consciousness and analytical methods, the historical verification of archival materials, and geographical information technology, allowing my work to flow freely across multiple disciplines. In recent years, my research has focused on three main axes. First, I comprehensively reconstruct the pre-relocation locations, social networks, and migration trajectories of more than 500 alpine indigenous villages, exploring the historical turns of relocation policies, factors influencing relocation, and how relocation methods led to the differentiation of social relations. Second, I investigate human interaction in ethnic borderlands, including intermarriage among Hoklo, Hakka, and Pingpu indigenous peoples. Third, I explore the phenomenon of the loss of native languages in Taiwan, analyzing whether family language affects educational achievement and subsequently leads to ethnic inequality. In addition, I attach great importance to the practical significance of academic research; sometimes, in order to respond to major issues of contemporary national and social development, I also venture beyond the aforementioned research axes.
