Research

As part of the collaboration between SSW and Oracle Labs I am working on the GraalVM project. My work focuses mostly on the LLVM IR interpreter Sulong and its interaction with other GraalVM-based language runtimes. For my PhD I am working on supporting dynamic taint analysis on GraalVM. The concept of dynamic taint analysis is to track the propagation of specific data while a program executes. My research addresses limitations of current implementations of this, such as language support and performance, by exploiting the capabilities of a managed runtime, more precisely of GraalVM.
