Research Interests

I am interested in research about wireless communications and machine learning.

Specifically, my research interests include:

The theory and development of wireless communications
Privacy-preserving deep learning
Wireless networking with deep neural networks.

I believe advancements in these areas can liberate humanity from labor and bridge information inequalities.

I am in graduate school with a dream to conduct research that contributes to a better world :)
