Alex Huang

Hello there! My name is Alex, and I currently work as a Machine Learning Engineer at Fetch Rewards . My research interests focus on applied deep learning, particularly in affective computing.

I earned my Bachelor’s degree in Computer Science from UW–Madison, where I had the privilege of working with Prof. Yin Li and Prof. Tim Rogers. Starting Fall 2026, I’ll be joining the University of Michigan to work with Prof. Emily Mower Provost.

Other Projects

Below are some of the non-research projects I’ve worked on. Feel free to take a look!

	3D Facial Feature Extraction repo Extract 3D Facial Features from videos and images using SOTA 3D face reconstruction model - EMOCA .
	Video Feature Extraction repo This directory contains the code to extract features from video datasets using mainstream vision models such as Slowfast, i3d, c3d, CLIP, etc.
