Professor Berger has been a Visiting Scientist at Microsoft Research and at the Universitat Politècnica de Catalunya (UPC) / Barcelona Supercomputing Center (BSC). Professor Berger’s research spans programming languages, runtime systems, and operating systems, with a particular focus on systems that transparently improve reliability, security, and performance.

He and his group are the creators of a number of influential software systems including Hoard (http://www.hoard.org), a fast and scalable memory manager that accelerates multithreaded applications (used by companies including British Telecom, Cisco, Crédit Suisse, Reuters, Royal Bank of Canada, SAP, and Tata, and on which the Mac OS X memory manager is based); DieHard, an error-avoiding memory manager that directly influenced the design of the Windows 7 Fault-Tolerant Heap; and DieHarder, a secure memory manager that was an inspiration for hardening changes made to the Windows 8 heap.

He served two terms on the SIGPLAN Executive Committee, a decade as an Associate Editor for TOPLAS, and was the program chair of PLDI 2016 and co-program chair for ASPLOS 2021. He received the SIGPLAN Distinguished Service Award in 2024.

His honors include a Microsoft Research Fellowship, an NSF CAREER Award, a Lilly Teaching Fellowship, the Distinguished Artifact Award for PLDI 2014, the Most Influential Paper Award at OOPSLA 2012, PLDI 2016, and ASPLOS 2019; best paper awards at FAST, OOPSLA, SOSP, and OSDI; five papers selected as CACM Research Highlights, a Google Research Award, and a Microsoft SEIF Award; he was named an ACM Fellow in 2019.
