PhD Students
I am particularly interested in students who have solid analytical foundation and are willing to use applied mathematics/AI techniques to tackle real-world problems. Drop me an email to request for more details. English requirement for PhD students (with or without a master degree): at least IELTS 6.5 or TOEFL 80. Consider applying via the Hong Kong PhD Fellowship Scheme -
Research Assistants/Associates/Fellows/Postdoctoral Fellows
multiple positions are available; working on various projects concerning convex and non-convex optimization, AI and machine learning, metaverse, variational convexity/analysis and mixed integer programming. Priority will be given to those who are interested in learning and understanding AI technologies.
