Research Focus

When testing software, we assume that a test passes if the code under test is free from failures for the input defined in the test and assume that the test fails if not. In other words, we expect a test to be deterministic, which doesn't always hold true. This kind of tests, that fail intermittently without changes to the code under test or the test itself are called flaky tests. My current research focuses on flaky tests in the context of continuous integration (CI).


Since November 2021, I am working as a doctoral research assistant at the Chair of Software and Systems Engineering (Prof. Pretschner). Prior to joining the Chair of Software and Systems Engineering, I've been working as a Data Scientist for Artificial Intelligence in the automotive industry. I hold a Master's degree in Robotics, Cognition, Intelligence from the Technical University of Munich.
