Geonwo Yoon


I received my B.S. in Computer Science from Pusan National University and am currently pursuing my M.S. at S3Lab under the supervision of Prof. Yoon-Ho Choi. My research interests include event collection and security in distributed networked systems and cloud-native environments, with a focus on eBPF-based runtime monitoring and ML-based anomaly detection.

Homepage Template

Feel free to use this website as a template! It is fully responsive and very easy to use and maintain as it uses a python script that crawls your bib files to automatically add the papers and talks. If you find it helpful, please add a link to my website - I will also add a link to yours (if you want). Checkout the github repository for instructions on how to use it.
