Research Philosophy

To know what you know and to know what you do not know—this is true knowledge.

— Analects

I approach research with the understanding that knowledge is always partial and contingent. This requires both precision in what can be claimed and restraint in what cannot. At the same time, I see educational research as inherently practical—its purpose is not only to explain systems, but to inform how they can better serve students.

Research Overview

My research examines how educational systems produce and obscure inequality—through both the distribution of opportunities and the ways those opportunities are measured and interpreted. Using large-scale and international datasets, I study how school structures, leadership, and instructional environments shape students' access, experiences, and outcomes. At the center of my work are three guiding questions: Who has access to opportunity? How do students experience schooling? What remains hidden in the data?

Access to Opportunity and Learning

Access to key academic opportunities—such as early exposure to advanced coursework—plays a critical role in shaping students' educational trajectories and learning outcomes. At the same time, instructional and organizational conditions within schools influence how these opportunities are experienced and sustained, contributing to persistent differences in student learning.

Student Experiences and School Contexts

Students' experiences in school, including belonging, safety, and interactions within diverse environments, are fundamental to learning and development. School contexts and climates play a critical role in shaping these experiences, influencing whether students feel supported, included, and able to fully engage in their education.

Revealing Hidden Inequality

Educational inequality is often obscured when diverse student populations are treated as homogeneous groups. Disaggregating data and critically examining measurement practices are essential for revealing these differences, particularly among Asian American and Pacific Islander populations whose experiences are often overlooked in aggregate analyses.
