Julian Nagele

Since spring 2024 I'm a compiler engineer at Apple. Before that I was a quantitative finance analyst at Bank of America. Earlier I was a postdoctoral research assistant in the Theory Group of the School of Electronic Engineering and Computer Science at Queen Mary University of London. Before that I was a research and teaching assistant and PhD student advised by Aart Middeldorp in the Computational Logic Group of the Department of Computer Science of the University of Innsbruck.

Projects

At Queen Mary I was a member of the project Logical Approach to Code Generation and Optimization, working on a novel compiler optimization approach based on constraint solving.

During an internship at Microsoft Research in spring 2017, I worked on Alive, a tool that can prove correctness of peephole optimizations.

At the University of Innsbruck I was a member of the following projects, devising tools for automatic and certified analysis of rewrite systems:

Teaching Activities

QMUL

In spring 2019 I delivered the module on Compilers at Queen Mary University of London.

ISR 2017

At the advanced track of the 9th International School on Rewriting, Vincent van Oostrom and I gave a course on commutation. You can find our material here.

UIBK

At the University of Innsbruck I was a teaching assistant for the following courses:

Supervised Bachelor Theses

I have (co-)supervised the following bachelor theses at UIBK:

Miscellaneous

I share many things with my partner Maria A Schett. For things we want to share in the future, and if you want to join in, download our list of ideas (password is the name of our hoover robot).

I'm a regular social badminton player and recreational runner. I ran in and would recommend the following races: Rock 'n' Roll Half Marathon Dublin 2019, EDP Lisbon Half Marathon 2017, Midnight Sun Run, Iceland 2014, BIG 25 Berlin 2013, Semi Marathon de Paris 2012.

My Erdös number is 5 (Nagele -> Middeldorp -> Avenhaus -> Plaisted -> Zaks -> Erdös).
