Cesar Cornejo's work addresses socio-political issues with particular focus in his native Peru and the way it translates into international contexts, through the use of multidisciplinary approaches that he has incorporated from his architectural background and his experience living and working in Japan, London, New York and Peru. 

His work includes architectural installations, conceptual projects that explore new models of relations between the individual and the built environment, sculptures that function as abstract representations of conceptual models, interactive installations that explore the nature of space and culture, installations that are spatially express the grief in society, performances that explore the boundaries of public art, photography turned into sculptures, paintings that explore relation with architectural space and drawings that blend bidimensional and three dimensional expressions while addressing his views on society and the environment.
