Dr. Oliver Bračevac

I am currently part of the Scala team at EPFL, LAMP working on the Scala 3 language and compiler, particularly capture checking and effect systems.

My general interests are programming languages, compilers, and formal verification. More details are available in my (somewhat outdated) research statement:

[Research Statement]    [Teaching Statement]

Previously, I was research engineer at Galois, Inc. contributing to DARPA projects on user-friendly verification tools for C and memory-safe imperative functional programming languages.

Before that, I was a postdoctoral researcher at Purdue, PurPL collaborating with Tiark Rompf on Scala LMS, high-performance symbolic execution, and Rust-style ownership type systems for Scala-like languages.

I earned my PhD from TU Darmstadt under the guidance of Mira Mezini, researching effect handlers for reactive and stream-based systems.

Earlier in my career, I worked as a systems and software engineer in the IT/telco industry.
