Previous Experience

Mikolas Janota graduated from Charles University in Prague, and got his doctoral degree from the University College Dublin. He held post doc positions at INESC-ID Portugal, and Cambridge, UK. 

Throughout his academic career he has been interested in the practical applications of logic and automated reasoning, especially in the context of software development and verification. He has actively worked on the development of the verification tool ESC/Java and the application of satisfiability (SAT) solvers for product configuration (logic-based recommendation system). Also, he has focused on algorithms for Boolean logic, e.g. maximum satisfiability, minimum unsatisfiability, or quantified Boolean formula (QBF). His QBF solvers were the winner for several tracks of the recent QBF competitions. At Microsoft Research, Cambridge, UK he has actively participated on the development of the Microsoft SMT solver Z3. 

Current Focus

He has been working on the development of Formal Methods and Automated Reasoning during his whole academic career spanning now over 16 years, which includes SW verification, SAT, MaxSAT, or SMT solvers. He is also contributing to the development of the SMT cvc5, and more recently, has been applying machine learning to improve SAT based solvers, mainly SMT (satisfiability modulo theories).

He is the head of the Formal Methods Research Group at the Czech Institute of of Informatics, Robotics and Cybernetics (CIIRC).
