郑琦，北京大学对外汉语教育学院助理教授、研究员，美国哈佛大学语言与读写能力专业硕士、美国马里兰大学测量、数据分析与评估专业硕士、第二语言习得专业博士。

[学术研究] 
一、研究领域
实验语音学、心理语言学、二语音系习得与认知加工、语言测试及心理测量学。
尤为关注跨语言音系习得与认知加工之间的密切关系，擅长结合行为学实验以及心理语言学理论研究，运用混合效应模型、多层次建模分析、结构方程模型（CFA验证性因子分析、MTMM多特质-多方法模型、LGCM潜在增长曲线模型等）、预测建模机器学习（Classification Tree分类树、Decision Tree决策树、Random Forest随机森林模型）等分析方法对第二语言习得中的音系习得问题进行深入探索。同时在语言测试与测量领域，擅长运用IRT项目反应理论（1PL/Rasch模型、2PL模型、3PL模型等）进行语言量表的效度分析、信度检验及设计优化。
