I am a Ph.D. candidate in Educational Psychology and Research Methodology at Purdue University, working under the guidance of Professor Hua-Hua Chang.
My research focuses on the continuous, dynamic monitoring of live test administration, closing the loop between test security and psychometric maintenance. My work spans three directions (click each to see the related publications):
🚨 Real-Time Examinee Monitoring
Securing test integrity by using process data to detect aberrant testing patterns and unauthorized AI assistance as they happen.
🔍 Real-Time Item Supervision
Ensuring continuous measurement precision by actively tracking item parameter drift and detecting compromised test content in live testing environments.
♻️ Real-Time Pool Replenishment
Building "self-healing" item banks through online calibration, Automatic Item Generation (AIG), and LLM-driven similarity analysis to instantly replace exposed items.
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).
