I am a Ph.D. candidate in Educational Psychology and Research Methodology at Purdue University, working under the guidance of Professor Hua-Hua Chang.
As testing unfolds, examinee behavior and item performance can change in ways that threaten the interpretation of scores. I develop real-time monitoring, in-session intervention, and continuous item-pool maintenance methods for adaptive, responsive, and self-renewing live assessment.
🚨 Real-Time Assessment Monitoring
Develop methods to monitor examinee behavior and item performance as live assessment unfolds.
🛡️ In-Session Intervention
Develop and evaluate interventions informed by monitoring evidence to improve the accuracy and fairness of ability estimation.
♻️ Continuous Item-Pool Maintenance
Maintain item pools across administrations through online calibration, content screening, and replenishment with AI-assisted item generation.
My research has been recognized and supported by the Ross Fellowship (2023–2026, 2027–2028) and the ETS Harold Gulliksen Psychometric Research Fellowship (2026–2027).
