Research topic: Quantum machine learning for reactivity

Project description: The generation of novel chemical matter with activity on relevant targets is the core business of the pharmaceutical industry. The ability to estimate the reactivity of such compounds would be valuable both for the initial chemical synthesis of these compounds and for assessing their stability under a variety of conditions. Quantum mechanical (QM) models enable simulations on reactivity and stability of these compounds through simulation of the bond-breaking and bond-forming events. However, these simulations come at a monumental computational expense. In recent years, quantum mechanical machine learning models have been developed which can provide accuracy comparable to quantum mechanical methods at a negligible computational cost. We will design and validate a neural network trained on reference QM data, which can then be used to predict reaction barriers and transition state conformations. This information can then be leveraged to inform chemistry decision-making.

Personal introduction: Early-stage researcher of the Advanced machine learning for Innovative Drug Discovery (AIDD) consortium, focussing on the development of quantum-informed machine learning applications for the prediction of reaction barriers and transition states structures.

My background is in theoretical physics, in particular I got my BSc from University of Florence and my MSc from University of Milan with a curriculum focused on quantum information, many-body theory and statistical mechanics. The master thesis project was done in collaboration with University of Turku (Finland), where I spend 4 months working on reinforcement learning applications to optimal control theory of quantum optical systems. This project ended with a publication on PRX Quantum which you can find here.

My current research is focused on developing machine learning applications that leverage quantum mechanical reference data in order to predict both reaction barriers and transition states geometries and features. My work goes in the direction of obtaining useful tools for chemistry decision-making, allowing for fast comprehension of the reaction paths of compounds.
