Welcome! This is Yuying’s homepage. (It’s still in construction … but it is serviceable now!)

I will regularly post some fun aspects about my incredibly exciting PhD journey in the form of blogs & photos, as well as share interesting scientific ideas that could possibly change the world.

This is my system

  • Research | Create | Travel
  • Be Energetic, Be Smart and Be Humble.
  • Think Big, Do Small, Dive Deep.
  • Insist on the Highest Standard.
  • Take Ownership.


Yuying wants to be an Applied (Engineering) Scientist, meaning, a person who appreciate the glory of Physics and Mathematics while also be able to Engineer the ideas to make them measurable.

Extract Info from Human Walking Data with Dynamic Mode Decomposition

This is my first post, I’ll do something very simple: ADVERTISE the methodology that our applied mathematicians use in data analysis. Unlike statisticians or computer scientists, we usually start from ‘dynamical system’ point of view. To give you a taste of what I mean, a method called dynamic mode decomposition (DMD) will be offered as …


Let’s get in touch! (Welcome bribes in the form of hotpot.)
