Luca Miglior
PhD Student in Computer Science
University of Pisa
Hi, I’m Luca (Figure 1), a PhD student in Computer Science at the University of Pisa, working with Prof. Davide Bacciu. I spend my time somewhere between deep generative models and graph machine learning.
Research
Lately I’ve been interested in how you can compose and steer generative models without retraining them. In CompFlow [MGB26a] (CompLearn @ ICML 2026) we show that simply adding up conditional velocity fields at inference time turns out to be a tempered Product-of-Experts, which takes classifier-free guidance from one condition to as many as you like, for free. It even works zero-shot on top of large text-to-image models. Before that, I used energy-based models on molecular graphs [MSPB25] to optimise chemical properties implicitly, with no explicit optimisation loop.
On the graph side, I’m curious about where message passing breaks down. In Can You Hear Me Now? [MTGB26] (ICLR 2026) we built a benchmark that measures how far information actually travels in a graph neural network, instead of guessing it from downstream accuracy. More recently, I’ve looked at Graph Transformer denoisers as dynamical systems [MGB26b]: standard self-attention gets more dissipative with depth and collapses node representations, while a non-dissipative, orthogonal variant keeps getting better as you add layers.
Background
Before the PhD I did my Master’s here in Pisa (110/110 cum laude), and worked as a research fellow on AI for healthcare. That meant a lot of smartphone accelerometers: measuring respiratory kinematics [VGM+24] and spotting cardiorespiratory conditions [SMG+25] with deep learning, published in Electronics and Computers in Biology and Medicine and funded by Regione Toscana. More in the CV.
Outside Research
I’m a licensed ham radio operator, callsign IU5WDZ, and radio is where my love for electronics meets the real world: there is something special about a circuit you built yourself making it onto the air. I especially enjoy QRP operation, making contacts on just a few watts (cool thing, cool vibe-coded thing here), and building my own DIY radios. When I’m not soldering, there’s usually something on the 3D printer, like the case of the ESP32-C3 in Figure 2, the little board this website runs on. Away from the desk and the bench, you’ll most likely find me on my road bike. More generally, I’m a technology enthusiast, happy to open up anything with a circuit board inside to see how it works.
