She studied Applied Computer Science in the Natural Sciences, and developed a typechecker for a compiler of a language for optimization problems. In her PhD project she developed metrics to compare forest data structures, with an application in molecular structure comparison. Working as a postdoc in cancer research on molecular structure prediction, she found her way to Brooklyn and Berlin.
