Axel's first paper, Code Transformation Rule Synthesis using LLMs: Potential and Limits, was accepted to ASE'26! (details here)
I joined the University of Rennes in 2023 as a tenured lecturer (maître de conférences) in the ISTIC faculty. I am also a member of the IRISA research centre within the joint Inria/IRISA DiverSE team.
My research in the DiverSE team focuses on the automated optimisation and evolution of software systems, with the aim of improving their functional and non-functional properties. To that end, I investigate techniques from genetic improvement, algorithm configuration, machine learning, and artificial intelligence, drawing particularly on evolutionary computation. This work builds on a previous postdoc at University College London on software specialisation and my PhD at the University of Lille on automated algorithm design for multi-objective combinatorial optimisation. As part of this research, I develop and maintain Magpie, a metaheuristic-based framework for automated software improvement.
At ISTIC, I teach master's-level courses in Software Engineering and Operational Research.
My name is typically pronounced [ɛm.(ə.)ʁik] [blo] in French. For English speakers, "Aymeric" sounds like the beginning of "emerald" followed by the name "Rick," whilst "Blot" rhymes with "go," with a silent "t." 日本語では「エムリック・ブロ」と発音されます。
Generative AI is an incredible technology that has been found genuinely useful in many applications.
But it is not magical; whilst it may appear fluent and convincing, at its core lie statistical patterns, not knowledge or causal understanding

Overall, although generative AI has clear merits, the current push towards its unbridled and accelerated integration into every aspect of work, education, and society is unsustainable and profoundly harmful to humanity, and its impact on nature is indisputable and unforgivable.
