Welcome to our new team member: Małgorzata Sulkowska.

Małgorzata Sulkowska got her M.Sc. in Computer Science in 2007 from Wrocław University of Science and Technology (Poland). The thesis, written jointly with Michał Przykucki, won second award in the Polish Mathematical Society contest for the best M.Sc. thesis in probability theory and applied mathematics. Małgorzata got her Ph.D. in Mathematics in 2013 from Wrocław University of Science and Technology under the supervision of prof. Michał Morayne. She got the assistant position at the same university already in 2012 and since 2014 she is an assistant professor in the Department of Fundamentals of Computer Science. In years 2015-2016 she spent 5-months as a postdoc at Federal University of Ceara (Fortaleza, Brazil) under the supervision of prof. Fabricio Siqueira Benevides. In years 2016-2020 she conducted a series of shorter research visits, among others, at University of London (Great Britain), Vienna University of Technology (Austria), University of Louisville (USA) and Inria Sophia-Antipolis (France). Since 2018 she has been a mentor of the Student Research Group Solvro at Wrocław University of Science and Technology. In 2019 Małgorzata was awarded a Miniatura3 grant from Polish National Science Center for research on stopping algorithms for graphs. In September 2020 she started a one-year postdoc position at Universite Cote d’Azur as a member of COATI team at INRIA Sophia-Antipolis. Her main research interests are optimal stopping problems, lying on the crossroads of graph theory, combinatorics and probability theory.

Welcome to our new team member: Ramon Aparicio-Pardo.

Ramon Aparicio-Pardo received a MEng in Telecom. and a Ph.D. from Universidad Politécnica de Cartagena (UPCT), Spain, in 2006 and 2011, respectively. His Ph.D. thesis, titled ‘Optimization and Planning of WDM Transparent Optical Networks,’ was distinguished with TELEFÓNICA Award for Best Thesis in Networking.
After two postdocs, at Orange Labs on optical switching networks (2012-2013) and at IRISA, in former IMT-Telecom Bretagne, on adaptive streaming (2013-2015), he joined Université Côte d’Azur (UCA) as an associate professor (“maître de conférences”) in Sept. 2015 and became a member of the SigNet group of the I3S laboratory. His main research interest is the optimal design and management of communication networks.

In September 2020, he joined obtained a “délégation Inria” to work with COATI on the design of AI-based methods for network optimization.

Emilio Cruciani recipient of a 2019 Testing and Verification research award

Emilio Cruciani and his co-authors (Breno Alexandro Ferreira de Miranda, Antonia Bertolino, and Roberto Verdecchia) won a 2019 Testing and Verification research award for their work on Static prediction of test flakiness.

Emilio Cruciani

Software companies invest a large amount of time in testing software. One of the problems they face during this process is that of “test flakiness”: some of the tests, instead of failing because of the presence of a bug in the software, have a nondeterministic behavior and could fail for external reasons (e.g., randomness in the software, concurrency, network latency, etc). When they are run multiple times on the same version of the software they could pass or fail and developer cannot rely on their outcome for the identification of bugs: When developers are asked to fix a potential bug found by a flaky test they could just lose their time since the bug is not there. The current approach to detect such flaky tests (and then treat them differently) is to rerun them: if they lead to different outcomes in different runs they are declared flaky. Of course this strategy is costly for large industries (e.g., Google runs millions of tests every day, out of which up to 16% are flaky).

Cruciani et al. proposed a fast, static approach to detect flaky tests based on machine learning techniques that proved to have high precision in our preliminary experimental results.
