Vojin believes that programs can be described in an abstract way and at the same time executed as quickly as their manually optimized counterparts. To this end, he is working Oracle Labs to improve dynamic compilation in multilingual environments. Before joining Oracle, Vojin received his Ph.D. in the Scala laboratory at the Swiss Federal Institute of Technology in Lausanne (EPFL), where he developed a platform for simply adding domain-specific optimizations to existing Scala libraries.
