I am an incoming postdoctoral researcher at the CISPA Helmholtz Center for Information Security in the group of Prof. Dr. Andreas Zeller. I completed my PhD studies in 2025 at HKUST, where I conduct research under the supervision of Prof. Shing-Chi Cheung within the CASTLE research group. Prior to that, I obtained my Bachelor's degree at SUSTech in 2020. My research work tackles the challenges in automating and enhancing software testing. I combine empirical studies of real-world testing practices with novel techniques for testing and debugging. My current projects span automated test generation, mocking, IoT testing, and metamorphic testing. I am interested in developing techniques that can automatically learn, infer, and validate software behaviors, which enable developers creating robust software systems.

As a technology enthusiast, I actively contribute to open-source projects. You can find more about my development work on my GitHub profile. Outside of technical pursuits, I enjoy hiking on Hong Kong's trails and photographing the scenic landscapes I encounter (Instagram). I also like making meals, especially Cantonese cuisine, and I often experiment with new recipes and traditional dishes. Sharing meals with friends and family is one of my favorite ways to relax and connect with others.
