Hi, everyone! My name is He Ren, and very welcome to my personal homepage! I am a Ph.D. student in the Measurement & Statistics program at University of Washington.

I am committed to the development and improvement of quantitative educational measurement methods and am always excited and amazed by the potential contribution that accurate measurement can make to educational equity. My research interests focus on Multidimensional Item Response Theory (MIRT), Differential Item Functioning (DIF), Computerized Adaptive Testing (CAT), and the application of machine learning in psychometrics.

I look forward to any potential collaborations. If you are also interested in the methodology or application of quantitative measurement methods, feel free to contact. Let’s make some fun!

When I am not working, I like hiking and photography.
