Hi! I am a postdoctoral researcher in Human-Computer Interaction (HCI) at the SENS and SELMET research units at INRAE and CIRAD in Montpellier (France) since September 2022.
My current research is on the engineering of graphical user interfaces and visualizations for socio-ecological contexts, and on doing research in interaction with various communities of practice. Its main outcomes have been:
My background is in software engineering, with long-time involvement in HCI and Competitive Programming (CP):
- Double engineering degree in Computer Science, HCI and CP, from Centrale Marseille and KTH in Sweden (Sept. 2008 – Oct. 2012).
- R&D engineer in Paris on developping the software for a digital TV recorder (Dec. 2012 – June 2014).
- Internship on gestural command interfaces supervised by Wendy Mackay in the ex)situ team at Inria Saclay (Mar. 2015 – Aug. 2015).
- PhD on the programming tools to design interfaces supervised by Stéphane Huot in the Loki team at Inria Lille (Nov. 2015 – Dec. 2019).
- Research assistant in Algorithmics, Software Engineering and Web Development at Centrale Lyon (Sep. 2019 – Aug. 2022).
Being very concerned about ecology, I have been a willing member of the Sustainable Development and Societal Responsibility local committee at Centrale Lyon, and am now co-chairing the French working group on HCI and ecology. I work hard to explore unconventional paths, most of my spare time going into compulsively crafting code then sharing it with engineering and academic groups.
For the most part my research has focused on reducing complexity when programming interactive systems. In the case of graphical interfaces, this complexity is due to the large number of objects and behaviors to manage, and I have proposed models [EICS'19, EICS'17] and principles [EICS'22] to give more concise mental representations. In the case of data structures, this complexity is due to the abstraction effort required to navigate between visual representation and code, and I have initiated a tool allowing to work directly on visual graphs [EIAH'21]. Finally, in the case of compilers, the complexity is due to the numerous transformations that lead from the source code to the executable file, and I explored the idea of a human-compiler communication to improve its understanding [PPIG'12].

(doctoral consortium) DOI PDF slides poster This section contains stuff that doesn't fit anywhere else. I believe technical mastery is essential to tackle impossible societal challenges, so I dedicate a good amount of time to organizing local training sessions for contests and challenges. These events are a lot of fun and a good way to test the skills of prospective students. My main platform for contests training is Kattis, where I hold the 2nd place in France.
