Hi! I am Zhanwen Chen (he/him/his), a Ph.D. student the at the Responsible AI in Varying Environments (RAVE) Lab at The University of Virginia.

My CV is here (updated February 14, 2024)

Research Interest

I am fascinated by one research question: can computers reason about visual and textual scenes like humans? In other words, how to extract, understand, memorize, and reason with semantic knowledge from both vision and text? I ground this long-term goal to the following research problems:

• How to understand the relationships among objects in scenes (WACV 2023).
• How to answer questions with social/emotional reasoning (ICDL 2020).
• How to enable vision-and-text reasoning in robots.

Fun things

I'm a classically trained pianist and a singer (baritone). My favorite composers are J.S. Bach, Sergei Rachmaninoff, and Francis Poulenc. Fun fact: at one point in life I almost became a professional pianist but I decided against the conservatory life. Here's me in concert (I come in at 1:07):

I love hiking and kayaking. I went on my first kayaking trip in Summer 2020 and since then the Vanderbilt ML armada has been terrorizing the rivers of Tennessee. I also enjoy traveling (pre- and hopefully post-COVID) and cooking various cuisines.
