Jingyu (Jack) Zhang







I am a CS PhD student at the Center for Language and Speech Processing, Johns Hopkins University, advised by Daniel Khashabi and Benjamin Van Durme.

I completed my undergraduate degree also from Johns Hopkins University majoring in Computer Science, Mathematics, Applied Mathematics and Statistics, and minoring in Economics. GO HOP! 💙🤍

My research interest lies in the area of Natural Language Processing, particularly on topics related to the safety, trustworthiness, and alignment of foundation models. In the past, I have collaborated with Mark Dredze at JHU CLSP, Yulia Tsvetkov and Tianxing He at the University of Washington, and Jim Glass at MIT CSAIL.

I was a course assistant for EN.601.465/665: Natural Language Processing, taught by Jason Eisner, in Fall 2022 and Fall 2021.

I was a section leader for Code in Place 2021, hosted by Stanford University.
