Biography

I’m a PhD student in physics at Université de Montréal, co-supervised by Michel Côté and Alex Hernandez Garcia. My interests have wandered from theoretical to computational physics and, more recently, to AI—especially generative models and graph neural networks—which I see as new and exciting tools in my physicist’s toolbox. I use them to explore topics from Raman spectra to battery materials and critical phenomena. Outside of science, I’m passionate about social justice, art, and learning new things.

Since joining Mila, I fell for its vibrant, welcoming community. I got involved in many (mostly unofficial) ways—the talent show, speed science competitions, the mending workshop, and student–administration discussions—until it felt natural to make things official and propose my candidacy as a LabRep. I’m grateful to the students who said yes. As a LabRep, I hope to be able to give back by amplifying student voices and supporting social events that bring people together.

I’m often told I’m a good listener—feel free to reach out if you need an ear or have ideas for us LabReps!

A Comparative Study of Molecular Dynamics Approaches for Simulating Ionic Conductivity in Solid Lithium Electrolytes
Accurate prediction of ionic conductivity is critical for the design of highperformance solid-state electrolytes in next-generation batterie… (see more)s. We benchmark molecular dynamics (MD) approaches for computing ionic conductivity in 21 lithium solid electrolytes for which experimental ionic conductivity has been previously reported in the literature. Specifically, we compare simulations driven by density functional theory (DFT) and by universal machine-learning interatomic potentials (uMLIPs), namely a MACE foundation model. Our results suggest comparable performance between DFT and MACE, with MACE requiring only a fraction of the computational cost. The framework developed here is designed to enable systematic comparisons with additional uMLIPs and fine-tuned models in future work.
Irresponsible AI: big tech's influence on AI research and associated impacts
The accelerated development, deployment and adoption of artificial intelligence systems has been fuelled by the increasing presence of big t… (see more)ech in the AI field. This trend has been accompanied by growing ethical concerns and intensified societal and environmental impacts. This position paper argues that irresponsible AI development is strongly driven by big tech's influence and involvement in the field. First, we examine the growing and disproportionate influence of big tech in AI research and argue that its drive for scaling and general-purpose systems is fundamentally at odds with the responsible, ethical, and sustainable development of AI. Second, we review key current environmental and societal negative impacts of AI and trace their connections to big tech's influence. Third, we discuss the underlying economic forces driving big tech's actions. Finally, as a call to action, we invite AI researchers to counter big tech's influence in irresponsible AI development through strategies that build on the responsibility of implicated actors and collective action.
Large scale Raman spectrum calculations in defective 2D materials using deep learning
We introduce a machine learning prediction workflow to study the impact of defects on the Raman response of 2D materials. By combining the u… (see more)se of machine-learned interatomic potentials, the Raman-active Γ-weighted density of states method and splitting configurations in independant patches, we are able to reach simulation sizes in the tens of thousands of atoms, with diagonalization now being the main bottleneck of the simulation. We apply the method to two systems, isotopic graphene and defective hexagonal boron nitride, and compare our predicted Raman response to experimental results, with good agreement. Our method opens up many possibilities for future studies of Raman response in solid-state physics.
