Bertrand Russell once said, “Mathematics, rightly viewed, processes not only truth, but supreme beauty.” This is also how I feel about mathematics: romantic, beautiful and extremely useful in explaining, modeling and improving our world.
My love for mathematics started with my love for artistic expressions. Since my sophomore year, I have been creating 3D printing designs and I found my inspirations from mathematics. My first 3D printing project was the Surprise Box. I used Mathematica to model a heart shape using the cartesian expression of cardioid and added some flowers by modifying Mathematica code published by János Karsai, an applied mathematician at the University of Szeged. I was stunned by the fact that we can use mathematics and computation to model real life objects so beautifully, with perfect symmetries and precisely defined shapes. I also started wondering: What else can I do with mathematics? Can I try to understand the world in a mathematical way? Can I make contributions to our society using mathematics?
Since then, my appreciation for mathematics has been growing exponentially, and it prompted me to pursue graduate study in the interdisciplinary field of applied mathematics.
I am currently completing my Ph.D. in Applied Mathematics at Harvard SEAS, under the guidance of Prof. Chris Rycroft, and expect to graduate in December, 2023.
In my graduate research, I use computational and mathematical tools to solve challenging problems and make tangible impacts in different scientific domains, including computational geometry, solid mechanics, and quantitative biology. You can read more about my work in the Research projects section.
In my free time, I like to explore expressive ways to combine my areas of interests together, for example, to use 3D printing/laser cutting to create mathematical art. In my graduate study, I have also co-designed and co-instructed a course on Generative Art and Scientific Visualization. In this way, I hope to share the fun and beauty of mathematical art with others.
