 My current research project -- and the main topic of my PhD thesis -- is about developing a *semantic model* of the [Rust programming language](https://www.rust-lang.org/) and, most importantly, its type system.
 Rust is an attempt of Mozilla to find a sweet spot in the design space of programming languages: A language that provides low-level resource management (making it a systems language), is convenient for programmers and guards against memory errors and thread unsafety.
-Other have [said](https://www.youtube.com/watch?v=O5vzLKg7y-k) and [written](http://www.oreilly.com/programming/free/files/why-rust.pdf) a lot on why we need such a language, so I won't lose any more words on this.

 Let me just use this opportunity for a shameless plug: If you are curious and want to learn Rust, check out [Rust-101](https://www.ralfj.de/projects/rust-101/main.html), a hands-on Rust tutorial I wrote.
 I am going to assume some basic familiarity with Rust in the following.

 But there are other reasons: It shouldn't be a surprise that [bugs](https://github.com/rust-lang/rust/issues/24292) have [been](https://github.com/rust-lang/rust/issues/25860) [found](https://github.com/rust-lang/rust/issues/24880) in Rust.
 There are lots of things that can be done about such bugs -- my take on this is that we should try to *prove*, in a mathematical rigorous way, that no such bugs exist in Rust.
 This goes hand-in-hand with other approaches like testing, fuzzing and [static analysis](https://homes.cs.washington.edu/~emina/pubs/crust.ase15.pdf).

 It doesn't matter *how* the function performs these operations.
 This is in contrast to the *syntactic* notion of well-typedness of a function, which involves looking at the *code* of the function and checking it against a bunch of rules.
 Only recently, research has been able to scale up such semantic methods to languages that combine state (i.e., mutable variables, a heap) with higher-order functions -- languages like Rust, where I can take a closure (a `Fn{,Mut,Once}`) and store it in memory, for later use.
-Lucky enough, my advisor [Derek Dreyer](http://www.mpi-sws.org/~dreyer/) is one of the world experts in this field, which permits me to intensively study Rust (which I would have done anyways) and call it research!
