Hello, this is JJ @KNU


Hello, I am Jeongju Sohn :)

I am an assistant professor in School of Computer Science and Engineering at Kyungpook National University. Prior to KNU, I got my Ph.D. in School of Computing at KAIST and worked as a Postdoc in the Interdisciplinary Centre for Security, Reliability and Trust (SnT), University of Luxembourg. My research interests lie mainly in software engineering, specifically in software evolution, testing, and debugging. I am especially interested in leveraging complementary relationships between different activities in software maintenance throughout software evolution

On-going Projects

Fault Localization to Defect Prediction and vice-versa

Latent Mutants and Latent faults

For more publications and past projects, please check my Google scholar and CV

In addition to those introduced here, I am currently working on explainable debugging, flaky web testing and robust locator generation for web testing (joined work with SnT, Universtiy of Luxembourg)
