Kevin Hyekang Joo

About Me | I am a Research Associate in the Robotics Institute at Carnegie Mellon University. Previously, I obtained an M.S. in Computer Science from the University of Maryland, College Park, advised by Prof. David W. Jacobs. My primary research interest is in Human Communicative Behavior & Affect Analysis using multimodal as well as spatiotemporal data.

Activities | Outside of research, I like to explore new food, engage in volunteer services, and listen to music. In addition, as a supporter of diversity, equity, and inclusion, I like to learn about the needs of those with disabilities and explore the potential solutions I can offer with my skills.

*I am currently looking for a Ph.D. position starting in Fall 2024!*

Why so enthusiastic about being a Teacher TA?

Knowledge is meant to be shared! I enjoy interacting with people and sharing my knowledge with others! Oftentimes, I serve as a guest speaker, too, at academic clubs, dicussing my research, industry, and academic backgrounds with fellow students! :)

Here are seven other reasons I strongly prefer to be a Teaching TA for CMSC131:

1. Greatly improves my skills for oral presentation
2. Forms social connections with newcomers
3. Excellent memory refresher of Java
4. Enables self-evaluation of my communication skill
5. Student-evaluation of my skills at the end of sem
6. Builds up confidence as a speaker
7. Solid setting for practicing my leadership,
     organization, and on-the-fly Q&A skills
