Yixuan He (何奕萱)

I am an Assistant Professor at Arizona State University. My research interests focus on, but not limited to graph neural networks, machine learning and mathematical modelling. In 2024, I completed my PhD (DPhil) degree in the Department of Statistics at University of Oxford.

It is my pleasure to be supervised by Prof. Gesine Reinert and Prof. Mihai Cucuringu during my doctoral studies.
In my free time, I enjoy table tennis (2022-2024 squad member and 2023-2024 President of Oxford University Table Tennis Club (OUTTC), winning Oxford Blues Award in the 2023/24 academic year), badminton (2022-2024 squad member of Oxford University Badminton Club (OUBaC)), piano, photography, and travelling.

I am recruiting PhD students (Statistics, Data Science, Analytics and Engineering, Applied Mathematics, Mathematics, etc.) and postdocs. Please contact me via email (please attach your CV, transcripts, and mention your research experience & research plan) if you are interested! Please note that I am not able to respond to every single inquiry, as I alreay have hundreds of inquiries in my mailbox. You can send me a reminder if you do think I should respond, but please do this sparingly. Thank you!
