Intro

Welcome!

Hello, world!

My name is Feng Zhu. I like math, science, programming, chess, music, photography, and soccer.

I graduated from UW-Madison with an MS in Atmospheric and Oceanic Sciences in Spring 2016. Now I am a Ph.D. student in Earth Sciences at USC, doing research on paleoclimatology.

Research Interests

So many interesting topics.

Atmospheric Modeling

When I was in China, I developed a simplified 2-D Cloud Resolving Model from scratch. Modeling atmospheric dynamics is much fun!

Numerical Methods

The development of cutting-edge numerical methods makes it possible to address analytically unresolvable problems.

Dynamical Systems

"Can a butterfly in Brazil really cause a tornado in Texas?"

Wavelet & Spectral Analysis

Investigating data in the frequency domain gives lots of insights that cannot be seen in the time domain.

Data Assimilation

Making sense of data.

Machine Learning

Given that I like math and Chess, machine learning and AI stuff are automatically interesting to me.

Education

Lazy isn't in my vocabulary.
