I am an Assistant Professor at Dipartimento Elettronica, Informazione e Bioingegneria of Politecnico di Milano (Italy) and visiting scholar at the University of Edinburgh.

My research interests fall in the broad spectrum of the computer system architecture field. Major topics are: (co-) design of computer architectures (including compiler, ISA, microarchitecture), computer systems, reconfigurable architectures such as FPGAs, heterogeneous systems, and design automation.

My research investigates how domain knowledge can be systematically embedded into computing systems, such as biomedical systems, aerospace systems, and quantum systems.

Other explorations: neuromorphic systems, whiskey aging (WHISKEY-AI workshop).

An experiment to better visualize my research can be found here (WIP).

If you are a motivated student, and curious or already share some of my research interests, feel free to reach out.
