I am a faculty at CISPA Helmholtz Center for Information Security, leading the Application Security (AppSec) research group.

These are currently our areas of interest:

Broad web security area (e.g., web vulnerability detection, analysis, measurements, etc.)
Program analysis (e.g., web application scanners, static program analysis, client and server-side code analysis, etc.)
Machine learning and artificial intelligence for program analysis
Security of immersive web applications (e.g., metaverse security and privacy, WebXR, etc.)
