My research ambition is to create techniques and tools that ease the use of interactive theorem provers for verifying code from various domains by focusing on one domain at a time. In particular, I am interested in developing domain-specific languages with sophisticated type-systems and with verified or certifying compilers to reduce the effort required for formally verifying code that fall in the respective domains. So far, most of my work focused on using interactive theorem proving to establish new results or to formalize and verify existing results from the following research areas: algorithms, programming languages, security, systems, logic, and social choice theory.

My current work focuses on using programming language and verified compilation techniques to reduce the effort required for producing efficient secure verified systems.
