Ph.D. Student · University of Padova · davide.buffelli [at] unipd.it

I'm a third year Ph.D. student in Information Engineering at the University of Padova, supervised by Professor Fabio Vandin. I have a broad interest in Deep Learning, with a current focus on techniques for structured data (geometric Deep Learning), and in particular Graph Neural Networks and Graph Representation Learning.

I hold a Bachelor's degree in Information Engineering and a Master's degree in Computer Engineering, both from the University of Padova. You check out my CV here.

I am currently a Research Scientist Intern at Meta AI in London. During my PhD I have been a visiting student in Professor Pietro Liò's group at the University of Cambridge, a visiting research in Dr. Bastian Rieck's group at Helmholtz Munich, and I've been an intern at Samsung AI Research (Cambridge).
