Peiyan Zhang

I'm a fourth-year Ph.D. student at the Hong Kong University of Science and Technology (HKUST), supervised by Prof. Sunghun Kim.

In 2020, I received my Bachelor's Degree in Computer Science and Technology, Beijing Institute of Technology with the Graduate Excellence Award of Beijing (2020) and National Scholarships (2017-2019).

From March 2022 to April 2023, I worked as a research intern at Microsoft Research Asia, supervised by Chaozhuo Li, and Xing Xie. My work on recommender systems won the Best Paper Award - Honorable Mention in WSDM 2023. I have won the Award of Excellence of Stars of Tomorrow Internship Program in Microsoft Research Asia (Top 10%).

Since August 2022, I am a visitor of Prof. Haohan Wang's group at University of Illinois Urbana-Champaign (UIUC), working on trustworthy machine learning systems.

From July 2023 to December 2023, I worked as a research intern at Beijing Academy of Artificial Intelligence (BAAI), supervised by Zheng Liu and focusing on large language models (LLM) & retrieval-oriented pre-training algorithms & end-to-end optimized information retrieval systems.

Currently, I am involved in pioneering efforts on Guard AI, an Automated AI Vulnerability and Defense Platform that secures AI systems for businesses. We specialize in monitoring, analyzing, and protecting LLMs without accessing internal data.

Research Interest

My research focuses on the development of trustworthy machine learning methods for e-commerce and financial applications, including time-series analysis, data mining, semi-/un-supervised learning, large language models and related applications such as recommender systems and financial quantitative trading. In my work, I use statistical analysis and deep learning methods, with an emphasis on data analysis using methods least influenced by spurious signals.

My research experience has equipped me with an in-depth understanding of how artificial intelligence can be used to solve complex, data-centric problems. The idea of applying these methodologies to the financial field and contributing to quantitative area is profoundly motivating.

Please feel free to drop me an email if you have a job position or other collaboration opportunity.
