Danja Vasiliev is a Critical Engineer born in Saint-Petersburg, currently living and working between Berlin and New York.

Vasiliev studies Systems and Networks through anti-disciplinary experimentation with hardware, firmware and software. Using computational platforms Danja engages in examination and exploitation of System and Network paradigms in both the physical and digital realms.

Based on these findings, Vasiliev creates and exhibits works of Critical Engineering.

Since 1999 Danja Vasiliev has been involved in computer-technology events, media-art exhibitions and seminars around the world. He has received a number of awards and mentions at Ars Electronica, Japan Media Art Festival, and Transmediale, among others.

In October 2011, together with his colleagues Julian Oliver and Gordan Savičić, Danja Vasiliev coauthored The Critical Engineering Manifesto.

Danja Vasiliev gives public workshops and talks, as well as regularly teaching courses on topics of network insecurity, software/OS modification, hardware re-engineering, digital forensics and other technology related subjects.
