Zichao (Jack) Wang

PhD Student at Rice University

Summary

I'm currently a 2nd year PhD student in Electrical Engineering at Rice University, working with Prof. Richard Baraniuk. My research lies at the intersection of machine learning and personalized education, where I develop novel machine learning algorithms automate certain tasks in large scale personalized education scenarios. My recent focus has been educational text analysis, such as question generation and free response grading. I am also interested in theoretical understanding of RNNs on natural language tasks.

During my undergraduate days, I specialized in signal processing, where I worked on a variety of real world signal processing problems involving audio and images, with mentorship of Prof. Gary Woods and Prof. Richard Baraniuk.

In summer 2015, I visited the Signal Processing Group at University of Oldenburg in Germany, working with Ante Jukic and Simon Doclo on speech dereverberation problem.

More About Me

I come from Wuhan (武汉), China, a city with almost the same weather and latitude as that of Houston (we've got real winter in Wuhan, though!).

I can speak English, Chinese and a bit German. I was in Germany for two out of my only three summers when I was undergrad, primarily because of my interest in the language and research program. Of course, I made well use of my time in Europe to explore many cities and countries.

I enjoy playing the violin and basketball (go Rockets!) In my spare time.
