3rd year PhD student @ NU
Ciao! My name is Federico Sossai and I don’t snack during talks :)
Among other things, I’m a third-year PhD student at Northwestern University and part of the ARCANA Lab led by Simone Campanoni.
At the moment I’m working on parallelizing compilers.
In my vision, a powerful langugage allows users to express high-level properties of their algorithms, while a powerful compiler should exploit them and minimize the performance cost of the abstractions that permit such expressiveness.
Nobody focusing on an algorithm enojys being distracted by a code that quickly gets unreadable and inflexible because of tedious implementation details.
When single-core performance is not enough, the problem is exacerbated by manual parallelelization techniques that, for example, require data structures to be reshaped or even worse, redesigned.
This is why I’m investigating the following questions:
Parallelism in scientific codes has been studied for decades with remarkable results. However, when programs are not dominated by well-structured array computation we are in dim candlelight. I believe that in the advent of an even more heterogeneous future, the importance of a compiler that understands and manipulates parallelism will be hard to overstate.

I’ve always had a strong passion for programming, since middle school. I’m fascinated by how much structure can emerge when enough thought is put into passing ideas through the sieve of algorithmic precision, and how these structures come back again and again. At the University of Padova, I realized how the love for learning did not only belong to computer science but extended to all the disciplines ruled by the rigor of math. For better or worse, calculus, electromagnetism, probability theory, and NP-completeness forever changed how I look at the world, and there’s no way back.
