To Prospective Students and Postdocs

  • Yes-Lab, led by Prof. Yanfang (Fanny) Ye at the University of Notre Dame, is a team consisting of faculty, postdocs and students with research focusing on AI/ML, data mining, cybersecurity, and public health. We very much enjoy developing novel yet elegant techniques to solve real-world problems that generate broader impacts. By harnessing large-scale, multi-source, multi-modality data, we discover new research problems, propose novel machine learning models, and develop advanced AI techniques for real-world driven applications in cybersecurity and public health. More specifically, we strive to (1) advance knowledge and science in graph learning, trustworthy LLMs, and multimodal learning, (2) bridge AI/ML and cybersecurity concentrating on AI security and safety, large-scale malware detection, and the study of the evolving underground ecosystem, and (3) develop AI and data-driven techniques to combat the opioid crisis and infectious disease outbreaks. Integrating humanity and technology, our long-term goal of research is to advance capabilities and trustworthiness of AI to provide state-of-the-art innovations i) to secure cyberspace for its users, and ii) to improve health and well-being of people around the world. Please refer to our research webpage for details of our works.

  • I am currently looking for multiple Ph.D. students and Postdocs doing supervised research or independent study with me in the CSE department at the University of Notre Dame. If you are a well motivated and dedicated student pursuing a Ph.D. degree or postdoc related to the areas of AI/ML, Data Mining, Cybersecurity, and Public Health, please send me an email with your CV. I aim to recruit 1 postdoc and 4 Ph.D. students for Fall 2025 (until filled).

    The postdocs will be provided with competitive packages and the Ph.D. students will be provided with multi-year research assistantships which cover the full cost of tuition and offer the full year (12 month/year) stipend and benefits. I will work with each postdoc or student to identify the most suitable topic based on his/her academic interests and background. I will also help each postdoc or student to build his/her strong capability and publication record as well as the career development with a good timing. I very much enjoy working with each member in my group and take each postdoc or student as a friend and a collaborator. Doing research is to build an enjoyable career and have fun.

    My expectations on perspective Ph.D. students are: (1) self-motivated, honest, diligent, intelligent, and easy-going personality; (2) strong research potential, programming capability, mathematical background; and (3) dedicated to research and willing to publish in prestigious forums. The minimum requirements for Ph.D. students are: B.S. in Computer Science (applicants with a master degree will be preferred), or related fields, and other general admission requirements.
