I am a researcher and teacher at KTH Royal Institute of Technology in the Theoretical Computer Science division and the STEP research group. I do research primarily on topics related to program verification and proof engineering.
I am interested in development of techniques and tools based on proof assistants for construction of functionally correct and secure software systems; see my research publications on DBLP and Google Scholar. I use Coq for both proving and programming and am a member of the Coq Team, where I help maintain the Coq opam archive, the Coq Platform, and Coq-community. I also use HOL4 and usually program in languages in the ML family such as OCaml, Standard ML, and CakeML.
