PhD in Computer Science. MSCA Postdoctoral Fellow at TU Wien. Making the Computing Continuum more performant and sustainable every day.

'Senza amore la verità non si vede'.
One of my first works was to estimate the remaining lifetime of network links at layer 3. This estimator was integrated in a monitoring system to re-route traffic ahead of time, avoiding failures before they happen. Interested? Read the work at doi.org/10.1016/j.co... #Research 🧪

Heuristics come with a risk: what if we cannot find a solution?
We proposed a solution to this problem, Multi-Layered Continuous Reasoning (MLCR).
MLCR uses multiple solvers to find a fast and efficient solution. Read the work at #Research #Continuum 🧪
