About Me

I am a Postdoctoral Researcher at FernUniversität Hagen (Germany), since 2021. Previously, I have worked as a Postdoctoral Research at University Koblenz-Landau (Germany). From 2016 to 2020 I was a PhD student at both Macquarie University (Sydney, Australia) and University of São Paulo (São Paulo, Brazil) under a cotutelle agreement. During my PhD, I have been addressing the problem of Belief Change in non-classical logics. This includes a number of logics such as temporal logics which are very important to both Artificial Intelligence (AI) and Formal Methods. My main motivation in extending Belief Change to non-compact logics is to allow the construction of enhanced and more realistic intelligent system in both AI and Formal Methods. My research revolves around Knowledge Representation, Logics, Non-Monotonic Reasoning and Formal Methods.
