I am a postdoctoral fellow in mathematics at Tsinghua University, Beijing. Previously, I received my PhD in pure maths at Harvard University. My undergraduate education comprised a BA in pure maths (the mathematical tripos) and an MMath degree (Part III) from Trinity College, Cambridge. My permanent email address is max.menzies at alumni.harvard.edu; my WeChat ID is max-menzies. My Chinese name is 孟思哲。 I'm currently in Sydney, still working on maths and Chinese.

Research

I am interested in both pure and applied mathematics. In pure maths, I spent my undergraduate and graduate years studying algebraic number theory and arithmetic geometry, particularly p-curvature. In applied maths, my primary collaborator (and best friend of 25 years) is Nick James. We try to work on various topical problems and develop new mathematical techniques to tackle them, with many experiments.

Papers

Apart from climate change, nothing is more important than accessibility of research, education, and information. I encourage all academics to submit their work to an open access repository such as arXiv. All my papers can be found on my personal arXiv page (see links below).

• Trends in COVID-19 prevalence and mortality: a year in review, with Nick James, 2021, submitted.

• COVID-19 second wave mortality in Europe and the United States, with Nick James and Peter Radchenko, 2020, to appear in Chaos: An Interdisciplinary Journal of Nonlinear Science.

• Association between COVID-19 cases and international equity indices, Physica D: Nonlinear Phenomena, 417 (2021) 132809.

• Changes to the extreme and erratic behaviour of cryptocurrencies during COVID-19, with Nick James and Jennifer Chan, Physica A: Statistical Mechanics and its Applications, 565 (2021) 125581.

Useful links

There's a nice function on arXiv to create a personal author page, where all your papers are lined up together. It's more reliable than searching by an author's name in the search bar. My my personal arXiv page is here.

I like the Mathematics Genealogy Project. Here is my personal page.

Finally, I'm a big fan of open source end-to-end encrypted applications. Signal is an alternative to WhatsApp that is actually encrypted rather than likely not, and its call quality is much better. Jitsi is an alternative to Zoom that is superior in every way. It is completely free, open source, encrypted, easier to use, and requires no sign-up to create a meeting.
