Hey, you have landed on the personal website of Michael Lingzhi Li, a PhD student at the MIT Operations Research Center.
To know about me, find the Who am I page. If you like what you see (I hope :D), follow me on the Social Media & Others tab.
To read my (scarcely updated) blog, check out the Recent Blogs on the right.
If you are really interested, you can go through the Research & Projects page - this includes some major projects that I have done in my life.
For notes concerning Cambridge undergraduate mathematics, access it through the Notes tab.
For MIT Notes, please login using Touchstone. Otherwise, it is hidden from your sight. :)
