• Hi there! I'm Zhenyu

    I'm currently a third-year Ph.D. student at the Electrical and Computer Engineering Department of UT Austin, working with Prof. Atlas Wang. Previously, I am fortunate to collaborate with Prof. Beidi Chen at CMU and Dr. Yuandong Tian at Meta.

    My reserach focuses on building efficient and reliable machine learning systems, specifically in the following topics: (i) Efficient training and inference for large foundation models; (ii) Adversarial & Backdoor Robustness, Privacy; (iii) Long context multimodal modeling; (iv) Transformer circuits & Quantum machine learning.
