Openings: I’m currently assembling an AI team at Havi Lab dedicated to developing a generative AI-based system for recruitment. If you are interested in the research and development of large language models, recommendation systems, and AI systems, please feel free to contact us. We will offer a competitive salary. See job_description for details.

I am expected to graduate in December 2024.

I am Zhilin Wang, currently in my final year as a Ph.D. candidate in the Department of Computer Science at Purdue University, Indiana, USA. I’m also affiliated with CERIAS at Purdue. I obtained my bachelor’s degree at Nanchang University in June 2020 and commenced my doctoral journey at Purdue in January 2021. My Ph.D. advisor is Prof. Qin Hu. I’ve actively contributed as a reviewer for prestigious academic journals and conferences such as IEEE TPDS, IEEE IoTJ, Elsevier JNCA, IEEE TCCN, and IEEE ICC. Additionally, I was a member of the Technical Program Committee (TPC) for the IEEE ICC’22 Workshop. My research interests are briefly described below:

• Decentralized Machine Learning. Implementing blockchain to achieve decentralized federated learning focuses on addressing the challenges of resource allocation on local and edge devices and straggler mitigation in a hierarchical system.
• Robust Machine Learning. Revealing the vulnerabilities of existing security mechanisms in federated learning and proposing lightweight and general schemes to protect industrial federated learning systems.
• Efficient Mobile Edge Computing. Designing efficient resource-sharing schemes to facilitate computational resource allocation on mobile edge servers.
• Large-scale Distributed Optimization. Designing efficient and robust distributed algorithms to solve large-scale optimization problems.
• Security & Privacy in Large Language Models. Toward improving the security and privacy protection of large language models during training and application.

In general, my research focuses on the system design, network optimization, and security protection of AI systems. If you are interested in my research, please directly email me.
